===== Syntax =====

<code php>
string md5_file(string $fileName [, bool $rawOutput = false ])
</code>

//(PHP 4, PHP 5)//

^ $fileName | The source file from which to compute an MD5 hash. |
^ $rawOutput | If this is set to true, output the result as raw binary. |
^ RETURNS | A message digest hash for the file referenced by **$fileName** or false if an error occurs (such as file not found). |

===== What it Does =====

Computes a message digest hash (MD5) for the contents of the specified file (**$fileName**).  This
file must exists on the local filesystem (where the script is run) otherwise the method will return
//false//.

===== Example =====

<code php>
// compute an MD5 hash for this script
$md5 = md5_file(__FILE__);
echo 'MD5 hash result: '.$md5;
