dest: Path of the resulting file.

返回值

成功时返回 TRUE，或者在失败时返回 FALSE。

范例

Example #1 xdiff_file_bpatch() example

The following code applies binary diff to a file.

 <?php
$old_version = 'archive-1.0.tgz';
$patch = 'archive.bpatch';

$result = xdiff_file_bpatch($old_version, $patch, 'archive-1.1.tgz');
if ($result) {
   echo "File patched";
} else {
   echo "File couldn't be patched";
}

?>

注释

Note:

Both files (file and patch) will be loaded into memory so ensure that your memory_limit is set high enough.
