Get interpreted size from ini shorthand syntax

Description

int ini_parse_quantity(string $shorthand)

Returns the interpreted size in bytes on success from an ini shorthand.

Parameters

shorthand: Ini shorthand to parse, must be a number followed by an optional multiplier. The following multipliers are supported: k/K (1024), m/M (1048576), g/G (1073741824). The number can be a decimal, hex (prefixed with 0x or 0X), octal (prefixed with 0o, 0O or 0) or binary (prefixed with 0b or 0B)

Return Values

Returns the interpreted size in bytes as an int.

Errors/Exceptions

If the value cannot be parsed, or an invalid multiplier is used, an E_WARNING is raised.

Examples

Example #1 A few ini_parse_quantity examples

<?php

var_dump(ini_parse_quantity('1024'));
var_dump(ini_parse_quantity('1024M'));
var_dump(ini_parse_quantity('512K'));
var_dump(ini_parse_quantity('0xFFk'));
var_dump(ini_parse_quantity('0b1010k'));
var_dump(ini_parse_quantity('0o1024'));
var_dump(ini_parse_quantity('01024'));
var_dump(ini_parse_quantity('Foobar'));
var_dump(ini_parse_quantity('10F'));

?>

The above example will output something similar to:


int(1024)
int(1073741824)
int(524288)
int(261120)
int(10240)
int(532)
int(532)

Warning: Invalid quantity "Foobar": no valid leading digits, interpreting as "0" for backwards compatibility
int(0)

Warning: Invalid quantity "10F": unknown multiplier "F", interpreting as "10" for backwards compatibility
int(10)
