找不到课程？

Question

我正在使用MCrypt.php

的index.php

include("MCrypt.php");

$crypter = new MCrypt();

MCrypt.php存在于同一目录中。

当我运行index.php时，我得到了

  

致命错误：未找到“MCrypt”类   第5行/home/username/project/index.php

更新：我尝试过只包含MCrypt.php但得到了同样的错误。我尝试重命名为.class.php并得到了同样的错误。

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

如果文件名为MCrypt.class.php，则包含而不是MCrypt.php，文件为MCrypt.php。

Answer 2

你的php文件必须以php开始标记开头。在课前，第一行必须是<?php

像这样：

<?php
    class MCrypt {
        ...
