Watermark Border
My site takes in a photo and currently adds a watermark to the bottom right as shown by the code at the bottom of this message. Instead i would like to take in an image like this: and turn it into a pic like this how could this be done? i guess the logical way to do it would be to create another image +40px on both height and width and then apply the original image to the centre of the new image. I would then need to get the border going around the outside in some sort of fasion. Code:

Two Equal Strings?
I was just checking php.net but couldn't find a function that will compare to strings. Did I just overlook it? or do I have to write a function to compare the two stirngs in php? If there is a function, which one is it? If there isn't a function, could you give me an idea of the coding that would compare two strings?
When To Use 2 Equal Signs And When To Use 3
When I had these two lines in my code: if ($executed == "The command didn't exist") { $this->core->error("In CommandRenderAllActionsInAnArray we sought the command '$commandName' but ExteriorCommands could not find it. It returned the value: '$executed'.", "CommandRenderAllActionsInAnArray"); I was getting this on screen: # CommandRenderAllActionsInAnArray threw this error: In CommandRenderAllActionsInAnArray we sought the command 'checkToSeeIfThisIsTheFirstLogin' but ExteriorCommands could not find it. It returned the value: Ƈ'. But if I change the first line to this: if ($executed === "The command didn't exist") { then it works correctly. Why does this need 3 equal signs? Why doesn't 2 suffice? I've done string comparisons before and I've never had to use 3 equal signs before.
Strcmp Vs Equal
I noticed in some examples to the encrypt functions of the PHP manual a syntax was used for password checks such as if (strcmp($userpassword, md5($_POST['password'])) == 0) { // do login } What is the advantage of this compared to if ($userpassword == md5($_POST['password'])) { // do login } ?
Making Fields Equal
I have two tables in a database and I have an html form. The tables both include a field called id# and that's how I have linked the tables in my SQL statement. I would like to set up my form so that when someone enters an id# it will write the value to the id field in both tables. Does anyone have any idea how I'd go about doing this?
How Can One Variable Equal 2 Things?
I'm having a problem that is baffling me... say I set a session variable as so: $_SESSION['temp'] = "default"; Now if I test the following two conditionals: if($_SESSION['temp'] == "default") and if($_SESSION['temp'] == 0) they both return TRUE. I don't understand why this is... if anything, I would have thought testing if it == 1 would be a boolean true since the variable exists and is not NULL, but testing if == 1 returns FALSE.
Two Variables, Equal Values - ?
After seeing a script programmed by a user in the beta-test section, I copied its premise - a man vs. dragon battle, with random damage being done. It just takes random numbers each time the page loads for damage values. That's all it does. However, whenever I play it, the end HP for both man and dragon are exactly the same. I need 2 things done, or at least to know how to do them - 1) I need to know how to fix the equal-HP problem 2) I would like it if someone could tell me how to achieve the effect of a <br>...tag within a PHP script. Here's the script! Code:
Equal Ratio Image With Netpbm
I'm trying to modify a script I am running for a gallery application. The script creates thumbnails properly, but only changes it based on width, which is a variable supplied in a sql table. I'm trying to modify the script so that it so that the width "and height" are no greater than that variable. Here is what I have so far: Code: <?php function RatioResizeImg($src_file, $dest_file, $gid) { list($dbconn) = pnDBGetConn(); $pntable = pnDBGetTables(); $column = &$pntable['meg_categories_column']; $query = "SELECT $column[thumbwidth] from $pntable[meg_categories] WHERE gallid=$gid"; $result = $dbconn->Execute($query); list($newWidth) = $result->fields; list($newHeight) = $result->fields; switch(megConfigGetVar('imageSoftware')) { case 'GD': return RatioResizeImgGD($src_file, $dest_file, $newWidth); break; case 'ImageMagick': return RatioResizeImgImageMagick($src_file, $dest_file, $newWidth); break; case 'none': return $src_file; break; case 'browser': return 'browser' break; case 'NetPBM': return RatioResizeImgNetPBM($src_file, $dest_file, $newWidth, $newHeight); break; default: return $src_file; break; } } function RatioResizeImgNetPBM($src_file, $dest_file, $newWidth, $newHeight) { /* Define where to find the various external binaries we need */ $netpbm = megConfigGetVar('netpbmPath'); /* default: home/www/pcmodeler/netpbm */ $djpeg =$netpbm."/djpeg"; /* decompresses a jpeg to ppm */ $cjpeg =$netpbm."/cjpeg"; /* compreses a ppm to jpeg format */ $pnmscale = $netpbm."/pnmscale"; /* scales a ppm image */ $pnmscale = $netpbm."/pnmscale"; /* scales a ppm image */ $jpgtopnm = $netpbm."/jpegtopnm"; /* convert a jpg to ppm */ $giftopnm = $netpbm."/giftopnm"; /* convert a gif to ppm */ $pngtopnm = $netpbm."/pngtopnm"; /* convert a png to ppm */ $ppmtojpg = $netpbm."/ppmtojpeg"; /* convert a ppm to jpg */ $ppmtogif = $netpbm."/ppmtogif"; /* convert a ppm to gif */ $ppmquant = $netpbm."/ppmquant"; /* colour quantize a ppm */ /* $imginfo = @getimagesize($src_file); if ($galleryvar['imageSoftwarePath'] == '') $cmd = $galleryvar['imageSoftwarePath']."/"; else $cmd = ""; */ if(!file_exists($dest_file)) { if(ereg(".gif$",$src_file)) { /* Look for .gif extension */ exec("$giftopnm $src_file | $pnmscale -width $newWidth ". "| $ppmquant 256 | $ppmtogif -interlace > "$dest_file""); } elseif(ereg(".jpe?g",$src_file)) { /* Look for .jpg or .jpeg */ exec("$jpgtopnm $src_file | $pnmscale -xysize $newWidth $newHeight".

"| $ppmquant 256 | $pngtopnm > "$dest_file""); } else { /* not a GIF, PNG or JPG file */ return(""); } } return $dest_file; } ?> So far, I can't get it to modify the width, so that portrait images are no larger than the variable. What am I missing?
Make Function Equal To String In Conditional
I can usually figure something out, but I CANNOT figure this one out: This is a classified word ad script to count the words in a text area ($wrdad) and multiply it by the rate for how many times the ad will run in the newspaper. I know my code is messy and ameture, don't be too critical, but it works - everythign except one part. We have a 15 word minimum. I have this area commented out as //Problem Area/// in the code below. In a nutshell, I want function wordcount($wordad) to be equal to 15 if there are fewer than 15 words in the $wordad textarea. It just seems to ignore the wordcount($wordad) == 15; in my conditional. Code:

Php Get Image Height Without The Use Of Input Box?
I'm looking around and it looks like there is lots of good info on pulling a var from php and using it in javascript, but no the other way around. All the info I can find says to just use hidden input boxes to hold the data, then post them with a submit button. But I have like 40 images, and I want to store their 'left' 'top' width' height'. Thats a lot of hidden input boxes to write (160+). It would be nice not to have those html'd into my script. Is there anyway to get the image height and set it as php data without a input box? Example: NOT THIS -----> <form method="post"> <input style="display:none" name="some image height"> <input submit> </form> document.getElementById("some image").height = $post_imageheight[]; I'm not sure if I explained this clearly enough. Let me know if you need more detail.

How To Choose The Correct Height/width For Images
I have users that submit images to my website. By default I choose to make the width bigger than the height because usually pictures are taken horizontally... But in some cases people take pictures vertically so what I'm getting at is... can I know whether an image was taken horizontally or vertically so I can make the proper width/ height lengths so that it looks nice and not kinda weird... because if you make the width bigger than the height of an image that is supposed to have a bigger height than width, it looks kinda ugly.. And also is there a way to know when I've enlarged the image too much? because if an image submitted was small and I make it bigger, then it also becomes kind of ugly to look at because I guess there aren't enough pixels...
GetImageSize() Vs. MySQL Query For Image Height/width
Does anyone know how efficient the GetImageSize function is? We're building a MySQL database with about 20,000 images and serving it with PHP. We're expecting 3000-4000 visits (not hits) per day and there will be about 5-10 images per page view. We want to keep load time to a minimum. Would we be better off including width and height info in the database for each image (and retreive with an SQL query) rather than using GetImageSize?
PHP Notice Fixes Table-layout: Fixwed; Height: 40px;
Just would be interested, if someone has seen the same behaviour: I have a page with a table, all formatted by CSS where table.classname{ table-layout: fixed; } and td.classname{ height: 40px; } This does for some reason not work,ie. it the td gets resized, when there is too much text in it. Funnily, when I put PHP code in the page, that throws a notice, it works.

Making Gmdate Output Equal Date Output
gmdate('F j, Y, g:i a',0) returns January 1, 1970, 12:00 am. How do I add to the second parameter of the date function to make it always return that same date, regardless of the time zone? Intuitively, it seems like date('F j, Y, g:i a',0 - date('Z')) should do it, but on my system, that's an hour off. Here's some sample code: <? echo gmdate('F j, Y, g:i a',0).'<br />' echo date('F j, Y, g:i a',0 - date('Z')).'<br />' echo date('F j, Y, g:i a',0 - date('Z') + 60*60); ?> And here's the output on my system: January 1, 1970, 12:00 am December 31, 1969, 11:00 pm January 1, 1970, 12:00 am Will the last echo always return the same thing as the first echo, regardless of the time zone? If so, why? It seems that the second one is the one that should do it - not the first one.
Sortable Columns
Hi there, I am new to this Forums...I am currently learning PHP and I was wondering if any of you guys knows how to make columsn in a table sortable. What would I have to change in the code? Thanks!
UPDATE Columns With PHP
So you know I'm going through Kevins book. I'm updating data in a test table. I'm adding names to each joke, say I have 7 jokes and 3 of them go to the same person. I can update each one seperately but I can't find a way of bulk updating. In this case it's not a problem. I've looked though Kevins book and a couple of others but can't find anything. Tried several sites to but I may just be searching wrong. I can do this: mysql> UPDATE Jokes SET AID="1" WHERE ID=2; but I'd like to update WHERE ID equals 2,3,4,5 all at once.

Sortable Columns
Does anybody know here how to make columns in a table sortable? I know that with a sql query I can accomplish that. PHP Code:
Grouping The Columns
Let's say I have a very simple Table: +---------------------+ | id | name | level | +---------------------+ | 1 | Adam | 1 | | 2 | Jack | 7 | | 3 | Bill | 1 | | 4 | Pete | 3 | | 5 | Ross | 7 | +---------------------+ but I want the PHP to output their id's and names, but group their Levels together like so: Level 1: Adam (id: 1) Bill (id: 3) Level 3: Pete (id: 4) Level 7: Jack (id: 2) Ross (id: 5) And then afterwards, If I create someone with a new level, PHP will automatically create a new heading (e.g. Level 10) and put the corresponding names under it. How should I approach this? Should my PHP contain two "while"s? Or do I use the SQL <group by> function?
Displaying Columns With A Value
what is the most efficient way to display column names from a database that only have the value '1' in its fields?? I cant seem to work it out, could someone give me a code example??
Creating Columns
I've been using this code to split records from a db into columns when it displays the data. Items are shown with 3 on a row and then a new row starts. It works really well but if ever there is only one item on a row it causes me a problem in this instance. I have far left and far right columns which display a background image, which is a border. The problem is this only works if there are three columns visible in a row. Is it possible to manipulate the following code so that there are always three columns present, they're just empty if there's no more records to fill them? Code:
In Email Form How Do We Say "must Be Equal To X"?

Count The Number Of Columns
I was wondering if there is a way to calculate the total of columns in a table? (something like $totalRows= mysql_num_rows($Recordset1); , but than for columns)
Best Practices For Sortable Columns
I have several forms that display information from the database after users log in. I would like the column titles to be sortable so that when the user clicks on a column heading, the data re-displays in sorted order of that column. Next time they click on it, it toggles the order from ascending to descending, and then back to ascending again. Since I have many forms and each form has different columns, I was wondering if there was a method that would be better than a brute force approach. What are the best practices for this functionality?
Query Results In 2 Columns?
I'm struggling to figure out how to do this properly. I have done a mySQL query to extract a list of names, and done a mysql_num_rows to determine how many results I've gotten. I want to split the list in to two columns. I've created $percol = $mysql_num_rows/2 but I'm not quite sure how to "loop" through the first half of the list, echo </td><td> and then list the balance. Can anyone give me some guidance on how best to structure this?
