说明

参数

old_file: Path to the first file. This file acts as "old" file.
new_file: Path to the second file. This file acts as "new" file.
dest: Path of the resulting patch file. Resulting file contains differences between "old" and "new" files. It is in binary format and is human-unreadable.

范例

Example #1 xdiff_file_bdiff() example

 <?php
$old_version = 'my_script_1.0.tgz';
$new_version = 'my_script_1.1.tgz';

?>

注释

Note:

Both files will be loaded into memory so ensure that your memory_limit is set high enough.
