PHP - Add X Every Nth Of $needle?

Hello,

I need to find the target html address within some raw html. I know it lies between Needle 1 and Needle 2 below.

Needle 1:
</span></a>&nbsp;&nbsp; <a href="

Needle 2:
" rel="nofollow"><span class=pn><span class=np>Next&nbsp;&raquo;</span></span></a></div>

Nornally I would just use the explode() function but my headache is that there are many instances of Needle 1 in the raw html code and I want my output array always have the same number of elements. However I do know that my target html address is directly after the last instance of Needle 1.

How should I go about splitting the html code into an array that always has 3 elements? I'd like the first element to include code up to and including the last instance of Needle 2, the 2nd element to have the target html address, and the 3rd element to have Needle 2 and any following code.

Thanks for any pointers (my main struggle is identifying the last instance of needle 1),

Thanks,

Stu

Hi all.

I've got this bit of code:

   $needles=array(`.`,`..`,`css`,`php`,`input_forms`);

   $t1=scandir($_SERVER['DOCUMENT_ROOT']);
   foreach($t1 as $t1_value){
      if(!is_dir($t1_value)){
         unset($t1[array_search($t1_value,$t1)]);
      }else{
         unset($t1[array_search($needles,$t1)]);
      }
   }


As you can see, I'm trying (in the else statement) to array search $t1 for everything in $needles, then unset the matches from $t1.  But its not working and I'm not sure why.  I also tried...

unset($t1[array_search(in_array($needles,$t1),$t1)]);


But that doesn't work either.  It only removes the "." directory from the array.  Any ideas on what's going wrong?

Hello all,

I'm trying to change the end of a javascript call based on the end of the url string. The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible!

at the moment i've got

Code: [Select]
<?php

       $url = $_SERVER['REQUEST_URI'];

     $tag = strstr ($url, 'sobi2Id=');

       echo $tag; 
?>
but this returns an unexpected T_STRING, expecting ',' or ';'

Can anyone debug this? I may well be being really silly!
