String List To Array
I'm trying to convert a slash-delimited string to an array, but I'm
wary of null elements that I want to eliminate. I'm frustrated with
explode(), array_unique(), and array_pop(), and I'm wondering if
there's a better way. I'm only interested in unique array elements.
Here's what I've got
$a = "10/20/30"
should become an array where
$b[0] = 10, $b[1] = 20, and $b[2] = 30.
Now here's the fun part. Often my arrays will have
$a = "10//"
I'd like that to become $b[0] = 10 and that's all.
So I tried applying array_unique() to explode("/", $a)
but you have to be careful about how many elements
are returned. Then I tried to use array_pop() to drop
the last element if it's empty, but array_pop returns
a scalar string when there's only one element left.
So when you use $b = array_pop($q), sometimes
there is no $b[0].

How Do You Convert A TCL List Into A String That PHP Can Read?
I have a TCL proc that needs to convert what might be a list into a string to read consider this: [set string [PROPER_CASE {hello world}]]; # OUTPUTS Hello World which is fine for PHP [set string [PROPER_CASE {-hello world}]]; # OUTPUT {{-Hello}} World, which PHP will print literally as {{-Hello}} World, instead of -Hello World Is there an easy way for TCL to brute-force a list into a strictly-string-only format to prevent this potentially ugly display from being displayed by PHP/etc.?

Sorting An Array Problem, (array/string Manipulation)
I have a function that I found on google, that goes through a directory and spits out a directory tree in an array, with arrays inside of arrays, and more and more arrays inside of arrays, depending on how many subdirectories are there..... Here is a sample "directory tree" it spits out. My problem is wanting to be able to create a new array containing only the paths to all the subdirectories it finds from this array, so it is with array manipulation... Not all paths are located in the topmost array's values, but some directories are within other subdirectories and so forth.. I'm stumped on how exactly to sort through this array, whether recursively or not to grab all the 'paths' in the array period. Code:

Setting A List Into An Array
I need some help creating a calendar display of sorts. I have a list of days as headings and under each day a list of events. Each event can have multiple bands performing. I have two tables: tbl_events & tbl_bands tbl_events contains the date, and show info and a field called band_ID which is a comma delimited list of each bands unique band_ID from table tbl_bands. Here's my problem. I want to take that list output: tbl_events.band_ID = 1,2,4,5,6 and set it into an array. If I set $band = array($rst["band_ID"]); and echo $band[0]; I get 1,2,3,4,5,6 what i need is: $band[0] = 1 $band[1] = 2 $band[2] = 3, etc....

Array: Re-generate The Key List?
I have a script that read information from a directory (using scandir()), and puts it in an array. Now I want to filter out all files and unvalid directories (ie: '.' and '..'), so that I keep the normal/visible directories. Than I loop through the array with a while(isset($array[$i])). When I use array_filter() to filter out the unwanted files/directories from the array, it will also delete the keys. So the keys arent for instance: 0, 1, 2, 3, 4, 5 but: 2, 3, 5 When I loop through the array it will say: key 0 (in the beginning, when $i = 0) is not set and so it will stop. How can I re-generate the keys so there wont be gaps between the numbers?

Dynamic Drop-down List In Array
Q. How do I create a dynamically-generated drop-down list for use in an array. I'm using PHP with a MySQL database (through phpMyAdmin) My database table is called com_courses, and I want to pull the distinct 'title' fields and have them appear as a drop down menu for the user to select in a form. Here is my array, with (at the moment) manually-entered 'titles' (which I now need to be dynamically generated from my database field: 'com_courses.title' array ( "coursetitle", "Course Title:", $EXTRA_SELECTLIST, array ("Report Writing", "Recruitment & Selection", "Presentation Skills", "Essential Telephone Skills", "Time Managememt", "Customer Care", "Other"), 0 ), I am not an experienced programmer, but can play around with php to customize programs. I've read up on arrays (I bought a "Programming with PHP and MySQL" book, but it just stops short of this problem). I can't figure this one out.

Array List Menu Problems
I am trying to store values from a List Menu into an sql database table as an ARRAY. However, when I select the multiple values from the form, it only stores the selected values as 'Array' in the SQL table. Here is the Select Statement: <select name="NOTES[]" size="9" multiple="multiple" id="NOTES"> <?php do { ?> <option value="<?php echo $row_literarydevices['LDEVICE']?>"<?php if (!(strcmp($row_literarydevices['LDEVICE'], $row_Recordset1['NOTES']))) {echo "selected="selected"";} ?>><?php echo $row_literarydevices['LDEVICE']?></option> <?php } while ($row_literarydevices = mysql_fetch_assoc($literarydevices)); $rows = mysql_num_rows($literarydevices); if($rows > 0) { mysql_data_seek($literarydevices, 0); $row_literarydevices = mysql_fetch_assoc($literarydevices); } ?> </select> Can anyone offer a reason to why the values are not being stored?

Dynamic Drop-down List With Array - Question
Can anyone out there give me a pointer regarding creating a dynamically-generated drop-down list connected to an array? And is that question as clear as chocolate spread? Here's what I've got. I'm using PHP and MySQL database. I'm customizing some calendar software, and I want the user to fill in a form by selecting a title from a drop-down list, generated by my MySQL database. However, the program I'm customizing uses arrays, which is where I'm stumped. What do I need to add to this code to make the array of titles(eg "report writing" etc) come from my database, rather than the manually-entered values that you can see here. The field I want to pull from is called com_courses.title array ( "coursetitle", "Course Title:", $EXTRA_SELECTLIST, array ("Report Writing", "Recruitment & Selection", "Presentation Skills", "Essential Telephone Skills", "Time Managememt", "Customer Care", "Other"), 0 ), I hope it's not cheeky to ask this, BTW I bought a book on Programming with PHP and MySQL, but it doesn't answer this question,

Retrieve Array From FORM List Of Values?
I have created a form where a user selects 2 items from a list of 8 values. That form field is called "choices" and returns a value to the php file as $choices. This form posed no problem when I only allowed a single item to be selected, but the client now needs to have 2 items selected at a time. The problem I'm having is that I don't know how to turn the multiple selections on the form in to an array. I thought the $choices variable would automatically become an array, but Using[color=blue] > for ( $i = 0; $i<2; $i++ ) > echo "$choices[$i] ";[/color] only returns the first two letters of the last selected item value. And [color=blue] > foreach($choices as $articles) > echo $articles. ' ' ;[/color] Returns an invalid argument. While echo $choices returns the second item selected in the list, but not the first. It appears that the variable is replacing the first item selected with the second rather than returning an array.

Create An Array From A List Of IDs Within A Database Table
I need to create an array from a list of IDs within a database table. The table consists of 3 fileds, a unique ID, a user ID and the last is an int value (item number) eg 1 3 7 2 4 5 3 3 2 etc... How would I go about using this query $query1=mysql_query("SELECT itemnumber FROM table WHERE userid = '{$user}'"); Would i be right in thinking I can use: $array = mysql_fetch_array($query1); to store all the item numbers associated with the user specified in the first query?

"Array To String Conversion" Error When Constructing A Multi-dimensional Array
I'm a bit stumped as I am getting a "Notice: Array to String Conversion" error when trying to do something that on the surface should be a very simple task - create an array, and write a set of values to them based on data submitted from POST Fields. Code below: $_SESSION["increment"] = array(); $x = 0 // Counter - This will be incremented $_SESSION["increment"][$x] = array("increment_bond" => $_POST["increment_bond"], "increment_amount" = $_POST["increment_amount"], "increment_comm_date1" = $_POST["increment_comm_date1"], "increment_comm_date2" =$_POST["increment_comm_date2"], "increment_comm_date3" = $_POST["increment_comm_date3"]); It keeps throwing out that error, and does not write any of the POST Values to the array (the POST values are definitely getting sent, so that is not the problem). If I dump out the value of $_SESSION["increment"], I get "1A" ?!? I'm sure that there is a pretty simple mistake lurking somewhere - I just can't seem to figure it out.

Is $Settings['string'] An Example Of An Array?
I'm still pretty new to PHP and I have a question. I know that variables are preceeded by a "$" (dollar sign). Typically, a variable has one value, unless it is an array. Then it is essentially a pointer to numerous values sequential in memory. The code I'm looking at now is using the same variable name, but assigning a different "index" to it, if you will. For example, I see the following: $settings['use_default_images'] $settings['doctype'] $settings['theme_url'] And many more. What is this feature called in PHP? I looked at the reference on php.net and it isn't anywhere to be found under arrays.

Check Array For A String
I am trying to set up a blacklist for a service I'm making. My current objective is to call up a .txt file which contains one domain name per line. I then take the user's input from a HTTP post and check to see if it contains the domain name. Here is my current non working script: //take user's input (example: http://www.somesite.com/files/photo.jpg) $filename = $HTTP_POST_VARS['filename']; //load blacklist in case of abuse $blacklist= file('blacklist.txt'); //check submitted image against blacklisted domains foreach($blacklist as $site){ if (strstr($filename,$site) !== FALSE) { echo "<div><h3>This site is blacklisted</h3></div>"; exit();}} This doesn't seem to work at all. I think it has something to do with the variable types, but I am too unfamiliar with this for Google to be a viable solution.
