rtrim() issue

[glenelkins]

Hi

 

lets say i have 2 vars like this:

 

$var1 = 'kernel.class.php';

$var2 = 'database.class.php';

 

I want to rempove the .class.php so:

 

$var1 = rtrim ( $var1, '.class.php' );

$var2 = rtrim ( $var2, '.class.php' );

 

Works fine! but when trimming the $var1  it comes back as 'kerne' not 'kernel'  but the $var2 is fine as 'database'  why is it removing the 'l' from $var1 ??

Because any character you put in the string as the second parameter will be trimmed.

 

'.class.php' means to trim any ".", "c", "l", "a", "s", "p", or "h".

Try this,

<?php
$var = "file.class.php";
$var = explode('.', $var);
$file = $var[0];
print $file;
?>

ah right i thought rtrim just removed characters in the order i type them as a matched string. perhaps i should just use preg_match or somethign!
