PHP - Preg_match_all Array And Foreach [warning: Noob Question]

I have noticed that if I run the preg_match_all function and use PREG_OFFSET_CAPTURE option to start capture somwhere in the middle of the string the second half of the string will be searched first returning the matching sections along with positions, then it goes up to the top half and returns matches from there too.
Is there way to parse only between start point and end of string?

I am running to an issue that I have never delt with before and am not sure if there is even a possible solution:

I have two files:

fileA  and fileB


fileA contains a loop that loops 30 times each time its called. in the loop there is a 2second delay


$i = 1; 
do { 
   $i++; sleep(2);
   if(!isset($_SESSION['user'])
  {
        break;
   }
} while($i < 31);



if fileB i have a simple destroy session

$_SESSION = array();
session_destroy();


I call both files via ajax, and that is where i run into my problem.

if I call fileA first, then call fileB through ajax, the code in FileB does not execute until fileA has run its course.

Is it possible to get around this?

Like set the priority of one over the other?

I keep getting the following error.

Hi , can somebody help me with this warning? Warning: Invalid argument supplied for foreach() in /home/wwwdesig/public_html/mailer.php on line 12 It´s just a simple php mailer Here is the php code:       <?php if(isset($_POST['submit'])) {

I am a total newbie at PHP and I have a wordpress plugin that works well but sometimes does not return any results to the query which I believe is causing this error:

Warning: Invalid argument supplied for foreach() social-media-integrated-related-content-smirc/lib/smirclib.php on line 182

From what I am reading on other forums the problem is possibly that the foreach loop is empty since the array must have elements. The solution being  to add a check above the foreach loop, to count the number of elements in the array, and if it is zero, skip the foreach loop. Is this correct? Here is the code....can someone please edit it so I can see an example of how it should be done? Again total PHP newbie so please be clear if possible. Thanks so much!!!

I'm not sure if the title explains it very well, but here is an image of it. I am trying to figure out how to access the option selected (equal, not equal, etc.), along with its input box, for each column (the checkboxes on the right) selected. The purpose of this is to allow a non-programming administrator user to create a custom query to access information. I can find out which checkboxes are selected no problem, but finding the accompanying drop-down option and input box is difficult for me. How do I do this?

If you have a suggestion on how to change it, I'm very open. Thank you in advance!

I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription.

I am trying to pull the shortdescription from the listings table with the query

$shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' ")));

The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories


Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462

The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them.

Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data?

Hi all i have a silly noob question....

When i directly query my database with the following i get the exact result i want.......

Code: [Select]
SELECT * FROM posts WHERE postTopic=3 AND postSubject=business;


However when i try this using the following PHP.......


$sql = "SELECT * FROM posts WHERE postTopic =" . mysql_real_escape_string($_GET['id']) . "AND postSubject='" . $_SESSION[forum] . "'";   


I get no result

I also get the correct results from


$sql = "SELECT * FROM posts WHERE postTopic =" . mysql_real_escape_string($_GET['id']) . ";   


and


$sql = "SELECT * FROM posts WHERE postSubject='" . $_SESSION[forum] . "'";   


mysql_real_escape_string($_GET['id']) is an integer and $_SESSION[forum] is a string.
 
I know this has something to do with the manner in which the query is passed with the AND and the string but i can't for the life of my work out where i am going wrong.

Thanks for any help.

OK so sorry if my understandings a bit off, but if a I want to introduce a class into my doc is the best way to fo this with the include() function?

I hope no one rolls their eyes at me, lol, but I literally, just made my first PHP script, but I ran into a snag.   Okay so the code I did was   <!DOCTYPE html>
<html>
<body>

<?php

echo <h1>"my First PHP script"</h1>;

?>

</body>
</html>   but in firefox the outcome is always "my first PHP script?> I had added the h1 tags because it wouldn't print at all before I did. I'm trying to figure out what I did wrong.

OK, so I have a question about databases and how they sort things being loaded into them. I have a database that I have images uploaded to (some people dont like to do it this way but this is what is going to work for my project).  I have it set up with an id column that auto-increments.  When I upload the files for some reason it is putting the highest id number first and the second one is the lowest then it goes in order from there.  Why would this be happening and how do I correct it?

I'm really sorry if this has been answered (I assume it has) I'm unfamiliar with search terms of what I am trying to do.

I have this web page

Code: [Select]
<html>
<body>


<?php
$con = mysql_connect("localhost","user","pass");
if (!$con)
  {
  echo "Fail";
  die('Could not connect: ' . mysql_error());
  }

echo "Triumph";
?>


</body>
</html>
Which I got from a snippet. I load the webpage expecting to see fail or triumph, but I see nothing.

My question is how to run the php script so I see something on the page (hopefully triumph.

I apoligise for my noobness, I'm a PHP know nothing at the moment.

Long story short i'm paginating database results. So pages = results / res-per-page-limit

but 28 / 10 will be 2.8 should i use round() or ceil()?
