BinaryPush( <binary-array>, <byte> )
Contents |
Description
Add a byte to the end of a binary variable.
Parameters
binary-array
The binary variable to use.
byte
The byte to add to the end of the binary data.
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, it is best to avoid using this too often.
Example
$binary = Pack("A*", "One"); BinaryPush($binary, Asc(" ")); BinaryPush($binary, Asc("T")); BinaryPush($binary, Asc("w")); BinaryPush($binary, Asc("o")); println( "'" . Unpack("A*", $binary, 3) . "'" ); // Prints: One Two
