reset(explode('_',$filename));
or
substr($filename, 0, strpos($filename, '_'));
سؤال
How can I get the prefix of the current page? i.e. if the current page is called adm_panel.php
, I would just like to extract adm_
. The prefixes for pages vary in length so doing a substr
for the first n
characters wouldn't work.
I can get the page name just fine:
<?php
echo '<p>' . basename($_SERVER['PHP_SELF']) . '</p>';
?>
But am stumped about how to get the prefix. Any ideas? I was thinking maybe regex?
Thanks.

You can use the following regex:
^[^_]+
This will match everything from the start to the first _ (not including the _)
Eg: adm
To get the _ as well, change to regex to:
^[^_]+_
Try this:
$filename = basename($_SERVER['PHP_SELF']);
echo '<p>' . substr($filename, 0, strpos($filename, '_') + 1) . '</p>';
