convertToBytes

convertToBytes

Converts a human-readable file size string (such as 2MB, 1.5 GB, or 512 KB) into its raw integer equivalent in bytes. This is particularly useful for parsing php.ini configuration values like memory_limit or upload_max_filesize.

Usage

convertToBytes(string $size): integer

Parameters

size (string) : The file size string to convert (e.g., 128M, 5GB, 2 KB).

Return Value

(integer) : Returns the converted size in bytes as an integer. : Returns -1 if the input string is exactly -1 (representing an unlimited configuration in PHP).

Conversion

The method dynamically parses the string using a regular expression defined by self::FILESIZEUNITS. It safely handles optional spaces between the number and the unit, and matches units case-insensitively.

Unit	Prefix/Matches (Case-Insensitive)	Mathematical Multiplier
Kilobyte	K, KB	Value x 1024
Megabyte	M, MB	Value x 1024^2^
Gigabyte	G, GB	Value x 1024^3^
Terabyte	T, TB	Value x 1024^4^
Petabyte	P, PB	Value x 1024^5^

Examples

$file->convertToBytes('2G') = 2147483648 
$file->convertToBytes('512 KB') = 524288
