ini_parse_quantity — Get interpreted size from ini shorthand syntax
$shorthand): intReturns the interpreted size in bytes on success from an ini shorthand.
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)
Returns the interpreted size in bytes as an int.
If the value cannot be parsed, or an invalid multiplier is used, an E_WARNING is raised.
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'));
?>以上示例的输出类似于：
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)
