BinaryPop( <binary-array> )
Contents |
Description
Delete the last byte from a binary variable.
Parameters
binary-array
The binary variable to use.
Return Value
Success: Returns 1.
Failure: Returns 0.
Remarks
Binary data is not really meant to be resized like crazy so if you have a LOT of data its best to avoid using this too often.
Example
$binary = Pack("z0", "1234"); println( "'" . Unpack("z0", $binary) . "'" ); // Prints: 1234 BinaryPop($binary); println( "'" . Unpack("z0", $binary) . "'" ); // Prints: 123
