Class not found? - php

Question

I am using MCrypt.php
index.php
include("MCrypt.php");
$crypter = new MCrypt();
MCrypt.php exists in same directory.
when I run index.php I get
Fatal error: Class 'MCrypt' not found in
/home/username/project/index.php on line 5
UPDATE: I have tried including just MCrypt.php but got the same error. I tried renaming to .class.php and got the same error.
class MCrypt {
private $iv = 'fedcba9876543210'; #Same as in JAVA
private $key = '0123456789abcdef'; #Same as in JAVA
function __construct() {
}
function encrypt($str) {
$iv = $this->iv;
$td = mcrypt_module_open('rijndael-128', '', 'cbc', $iv);
mcrypt_generic_init($td, $this->key, $iv);
$str = $this->padString($str);
$encrypted = mcrypt_generic($td, $str);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
return base64_encode($encrypted);
}
function decrypt($code) {
$code = base64_decode($code);
$iv = $this->iv;
$td = mcrypt_module_open('rijndael-128', '', 'cbc', $iv);
mcrypt_generic_init($td, $this->key, $iv);
$decrypted = mdecrypt_generic($td, $code);
mcrypt_generic_deinit($td);
mcrypt_module_close($td);
return utf8_encode(trim($decrypted));
}
protected function hex2bin($hexdata) {
$bindata = '';
for ($i = 0; $i < strlen($hexdata); $i += 2) {
$bindata .= chr(hexdec(substr($hexdata, $i, 2)));
}
return $bindata;
}
private function padString($source) {
$paddingChar = ' ';
$size = 16;
$x = strlen($source) % $size;
$padLength = $size - $x;
for ($i = 0; $i < $padLength; $i++) {
$source .= $paddingChar;
}
return $source;
}
}

Answer 1

your php file has to start with the php opening tag. the first line, before the class, has to be <?php
like this:
<?php
class MCrypt {
...

Answer 2

Including instead of MCrypt.class.php, the file is MCrypt.php if the file is called MCrypt.php.
