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)

返回值

示例

示例 #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'));

?>

以上示例会输出：

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)
