possible error in the script?

I tried to run script and got:

A non well formed numeric value encountered

Line

realpath_cache_tuner/realpath_cache_tuner.php

Line 12 in 86b60d3

$last = strtolower($value[strlen($value) - 1]);

gets last symbol and transforms it to lowercase, but whole string in such case is not transformed and contain that symbol!

And next lines:

realpath_cache_tuner/realpath_cache_tuner.php

Lines 13 to 20 in 86b60d3

    
           switch($last) { 
        
               case 'g': 
        
                   $value *= 1024; 
        
               case 'm': 
        
                   $value *= 1024; 
        
               case 'k': 
        
                   $value *= 1024; 
        
           }

what is the difference? any case inside switch do exactly same task.

UPD oops, I missed there are no break statement. ok, anyway $value is still seems incorrect for calculations.

UPD2 I think next code after line #12 may fix that issue:

if ($last) $value = substr($value, 0, strlen($value) - 1);

What do you have in $value when it errors?

4096K

-- string returned by ini_get('realpath_cache_size')

Fixed with 1d84ab8. Thanks for reporting!

	switch($last) {
	case 'g':
	$value *= 1024;
	case 'm':
	$value *= 1024;
	case 'k':
	$value *= 1024;
	}
