function return_bytes($val) { $val = trim($val); $last = strtolower($val{strlen($val)-1}); switch($last) { // The 'G' modifier is available since PHP 5.1.0 case 'g': $val *= 1024; case 'm': $val *= 1024; case 'k': $val *= 1024; }
When querying boolean values:
A boolean ini value of off will be returned as an
empty string or "0" while a boolean ini value of on will
be returned as "1".
When querying memory size values:
Many ini memory size values, such as
upload_max_filesize, are
stored in the php.ini file in shorthand notation.
ini_get() will return the exact string stored in the
php.ini file and NOT its integer
equivalent. Attempting normal arithmetic functions on these values
will not have otherwise expected results. The example below shows one
way to convert shorthand notation into bytes, much like how the PHP
source does it.
