Adding New Values To An Array That Already Contains Values..
is it possible to append new values to an array that already has values in it??

say, i have my existing array;

existing array;
$array = array([66314] => 66314 , [66315] => 66315) ;

then , when i check my checkbox on my next page, the ids should be appended to the $array:

array that needs to be added to the $array;

$array = array([66316] => 66316,[66317] => 66317,[66318] => 66318);

how should it be done??

$lang="english";
$nomusic="true";

Which is faster for the server to process:

HTML inside echo tags or outside of PHP altogether?

Echo To Php
I know it may seem odd, but is it possible to echo to php? I mean
neasting php within php?

example

<?php
$array_levels="[1][2][3]";
$my_array<?php echo $array_levels; ?>="hello world"
?>

It may seem stupid but would be powerful, wouldn't it?
How can I accomplish what I just did differently?

Echo Or Not To Echo?
I have a couple pages that have tables, whats best use echo to produce the
full table with the variables or is it best to just make the table in plain

Example, I have tables like this:

PHP In Echo
Is it possible to put PHP in an echo? If so, how would I?

Echo
I am either too tire to think or not seeing it. I have a echo statement as follows:

echo "Flight request date: " . "$date = $flight['Dept Date']"; does not display as suppose to. I am missing something?

PHP In Echo

Echo Within Echo
Essentially, I want to incorporate some captcha code that I have working elsewhere in a simple form element into some more complex php code.

Basically, I currently have:

content .='blah blah';
content .='blah blah';

echo $content
However, my captcha code is as follows:

<img src='captcha.php?f=<?php echo $f;?>'>
$f is declared earlier with the relevant randomisation code.

However, if i combine the above into:

content .='blah blah';
content .='blah blah';
content .='<img src='captcha.php?f=<?php echo $f;?>'>';

echo $content
The captcha image displays but it is always the same image - it does not randomise.

Echo...

Echo Before Value?
I was wondering if there's anyone to do the echo before saying what the echo of the value is.

<?php echo $header; ?>
<?php $header= "test"; ?>

Displays nothing, while doing that backward of course does since it reads the page top to bottom.

I'm splitting the pages into header and footer and want to header (title of the current page) to be like this so i can just start my pages off saying what the page is with the header= "blah blah blah"

Echo A URL
i want to run and if statement and if something is true then redirect the user to another page.

How Is Echo Implemented In Php
When used with the command line interface, echo writes to the stdout,
whereas in a Web environment, it writes to the response stream. How is
it implemented inside PHP?

Does it write to a stream?

Target For Echo
is that possible to assign a target for echo? I have this when i submit a form. PHP Code:

Varchar Col, Cannot Echo It All
I am in debug mode. And echo values passed from a query to another page
For example: $sub_cate_title= mysql_result($result,$i,"sub_cate_title");
The value is made out of two words like aaa (there is a space between) and bbb
Instead of echoing aaa bbb I only get the first part aaa. However the data is fully entered in the DB.

Echo Problems
i am just modding a scipt and i cant seem to get a function to work. PHP Code:

No Echo After Include?
<?php
echo "bbb";
include("common/funcs.php");
echo "a";
?>

When accessing the above test code from a browser it prings 'bbba.'
When accessing the page from a MFC app, it just prints 'bbb.'
Everying print or echo statement after the include gets ignored. Why
would this be?

Echo Vs Print
What's the difference between Echo and Print?

Why Won't Variable Echo?
Just moved web hosts and noticed that this:

<?php echo "$f"; ?>

used to work when there was an ?f= in the URL like so:
http://www.mydomain.com/index.html?f=yes

Now it doesn't at the new host.

I want to echo out "yes" in the HTML.

Echo And Print()
I'm wondering about the differences (if any) between echo and print(). The PHP Manual tells me that echo is a language construct and not a function so therefore it doesn't need parenthesis to encapsulate it's arguement(s), however I often use print() without parenthesis as well.

Does anyone know of any significant differences between these two functions/constructs and the ideal application for both? Up until now I have always used print().

Maths In Echo?
echo "<a href="content.php?categ=$categ&lower=[j]*5">$id[j]</a>";

The echo above is in a while loop, what is the best way of getting the lower variable in the link to be equal to 5 times the value of j (the number that increments by 1 each time the while loop runs through). Obviously [j]*5 will not work, so just wondering what will?

Print Vs. Echo
How echo command is differne from print command in PHP?

Echo Statements
I'm trying to change the user password - how? First, the user enters his old password, enter the new password twice. If the old password does'nt match with that of in the table, displays an error message.If the new password entered twice is not the same, also displays an error message.

If the old password matches with that of in the table and the new password entered twice is same, then the password is updated.MY CODE ALSO WORKS ABSOLUTELY FINE!!!! But, I've problems in displaying these error messages - Like,

1.If the old password does'nt match with that of in the table,and the newpassword which is entered twice is same, it has to display an error message "Old password is wrong"
2.If the entered old password matches with that of in the table, and the new password which is entered twice does'nt matches, then it has to display an error message "New password does'nt match"

3.If everything goes well, it has to display "Password updated successfully" PHP Code:

Echo Vs. Print
I'm new to PHP and am curios if there is any functional difference between a "print" and an "echo".

Add Href= Tag To Echo
Is it possible to add a "href=" tag to an echo line.

Something like this:
echo "<b>$name</b>,<br>Sorry there's a problem sending your message. Please
try <a href="/mail.html">again</a>";

Echo VARIABLES
I have a mysql query that grabs data from the table ... the data is
"variable names" something like $home $about $contact

I need the loop to echo those variables as PHP Code, so that they are
replaced with the variable value and not the variable name.

any quick function for that?

Echo A String That Contain <? And <?php
How can I echo a string that contain <? and <?php?

For example,

$str="test <? and <?php echo";
echo $str;

What I get is: test instead of: test <? and <?php echo

Echo Vs Print
In case anyone was wondering I decided to test which was quicker using 2 different size strings, one a small 25 character the other a big > 400 character for echo and print. Here were my results:

small results
echo = 1.49350118637
print = 1.50529193878

big results
echo = 32.9350512028
print = 31.7385149002

As you can tell there is really not much of a difference between the two. With 50,000 lines printed for each there is not much a difference. A hundredth of a second for the small string and 1.2 seconds for 50,000 lines for the big string.

Just kind of an FYI for everyone, it does not really matter which you use, either is very efficient for the amount that most people print =)

Echo Ping
What I am trying to do is setup a small ping. I was wondering if anyone knew how to setup a ping to ping a website/ip and echo it out to display on a webpage.

Echo In A Color
I cant figure out how to echo in a color. Here is my code:

echo "<font color='#ff1200'>State / Territory Field Missing<br></font>";
the error that i receive is:

Parse error: parse error, unexpected T_IF in /home/galaxyto/public_html/phpharvest.php
I remove the font tag and the script works fine.

Color Echo?
I just started learning PHP and I am trying to read form data and then display it using echo. Here is what I am using echo $row["title"];

Basically i want to limit the ammount of data echoed. So say someone types a 1500 word description about themself, i want to just echo 250 characters of that. is there a way to do this?

PHP To Echo Results
This may seem very complicated, but I have a list of members from student council. Each has a record of attendance in their own column. (Each row is a different meeting). How can I query the database with php to count how many e's u's and p's there is in a column? How can I do a simple loop to do this and repeat it over many times?

e stands for excused
u stands for unexcused
p ............. present

Escaping Echo '';
Is there away to do the following which has errors:

<input name="email" type="text" value="'.$email2.'" size="30" /> '. if (empty($email)) { '*' } .'
rather than having to break out of the echo through out my table like so:

echo '<input name="email" type="text" value="'.$email.'" size="30" />'; if (empty($_POST['email2'])) { echo '*'; }

Echo File MD5
Any idea why this:

echo "MD5: " . md5_file($_FILES["file"]["file"]);

Php Echo Td Width
I am unable to make a tds width any larger using either print of echo in the following code

Using A Function Within A Echo
I'm having a little trouble getting a function to work properly within a echo. It seems to me that this problem is something really simple, but I just can't quite put my finger on it .

The function does execute within the echo, but its being displayed in the wrong order. I dont know whether it is a CSS problem, HTML problem or a PHP problem, or all of the above. Code:

Echo HTML
How do I use echo to print out HTML. I want to be able to use it an a conitional statement and just regular. For example

if (mysql_affected_rows() == 1) { //( HOW DO I ECHO HTML HERE))?

Echo Images
Here is the code line within php tags:

This line works if I echo words
echo "<a href=payment.php>Click here to purchase a membership.[/url]";

But echo image doesnt work
echo "a href=payment.php><img src="images_files/button_upgrade.gif">[/url]";

I get a Parse error: syntax error, unexpected T_STRING, expecting on the page because the script cannot echo the image. I dont know how to write the code correctly so that image would show up that people can click on.
