说明

bool xdiff_file_bpatch ( string $file , string $patch , string $dest )

参数

file: The original file.
patch: The binary patch file.
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.
