Translate Perl to PHP for me please

I know almost nothing about php, and I can't for the life of me figure out how to translate this correctly. Here's a perl version of what I want to do in php:

$request = "$ENV{'REQUEST_URI'}";

if (($request ne "/")&&($request !~ m/index.php/)) {print $myadsensecode;}

Code (markup):

Here is the PHP code I have now:

<!-- ONLY SHOW THIS TEXT ON SUB PAGES -->
<?php
$AC_Onlyshow = $_SERVER['REQUEST_URI'];

$ADSENSE_CODE = <<<ADSENSECODE
<div style="display:block;float:left;padding:5px;">
<!-- ADSENSE BLOCK -->
</div>
ADSENSECODE;
?>

<!-- END ONLY SHOW THIS TEXT ON SUB PAGES -->

<!-- LATER ON IN THE PAGE -->

<?php if ( $AC_Onlyshow != "/") {
    echo "$ADSENSE_CODE";
}
?>

Code (markup):

It's for a wordpress blog - I want the adsense to show up on individual pages, and that part works: but my problem is when searches are done: it'll show the adsense code for every post which would cause issues with Google . . .

The only thing I need translated is this part:

&&($request !~ m/index.php/)

Any help would be appreciated.

thanks.

 

I've tried bare bones Babelfish translation for
&&($request !~ m/index.php/) and got that:

 && ( strpos($request,'index.php') === false ) 

Code (markup):

Hope that helps.

 

Hi,

I tried the above code. . . and wordpress didn't like it too much.

I think what I'm looking for is something that uses preg_match - but I don't know how to create regular expressions in php - only perl.

Nor do I know how to do the if ((!$something)&&($not eq "$somethingelse")) {&whatever;} - I'm not exactly sure if the && is correct.

Any more ideas on this?

 

I found what I was looking for, and I wanted to post the solution here in case someone else was looking for it to.

Here is the translation of what I was looking for:

<?php if ( $AC_Onlyshow != '/' && (!preg_match("/\/index.php+?/","$AC_Onlyshow")))
{
    echo "$ADSENSE_CODE";
}

?>

Code (markup):

While this does what I was trying to do, namely removing the adsense code from the search page. . . it does nothing for the archives nor the category pages. . . .

I guess maybe I should just look for an already developed plugin, but it was fun to try & pick up some php in the meantime.

Thanks.
