PHP的MD5哈希函数返回500内部错误

Question

I am trying to create a md5 hash for a string but the problem is that whenever I use md5 function and run the file, it returns a 500 internal error.

the code i am using is

$php_hash_string = md5("test_hash");

When I comment out the file the error is not produced and the rest of the output is printed out but when i use the md5 function it generates 500 internal server error.

Can anyone please help me solve this problem?

Server info: LAMP on CentOS 5.6

Answer 1

I don't know if you want to use this way, but at least try it.

$md5 = md5("test_hash");
$php_hash_string = $md5;

It's probably just stupid try, but mostly only stupid things make problems.

And put in top of the file this:

error_reporting (E_ALL ^ E_NOTICE);

Answer 2

the code i am using is $php_hash_string = md5("test_hash"); When I comment out the file the error is not produced and the rest of the output is printed

So that's not the code you are using, only a part of it.

The first step is to confirm that it really is the md5() call which is causing the problem. Do you still get problems with a script containing only that one statement?

it returns a 500 internal error.

Have you verified that your installation is correctly configured to report/log PHP errors? And that it is not logging errors when executing the md5 function? And there is nothing related to this logged by the webserver? eg try:

<?php
 for (
?>

(this should produce a fatal parsing error)

确保您执行yum install php-mcrypt，看看是否有区别
