Question

我的代码存在此问题，我收到此错误，我不确定它的含义。

Warning: file_get_contents(http://www.minecraft.net/haspaid.jsp?user=xCodr) [function.file-get-contents]: failed to open stream: Permission denied in /home/www/tripex-network.com/core/classes/Validate.php on line 60

任何人都可以向我解释如何解决它。

这是我的代码：

<?php

            $_errors = array(),
            $_db = null;

        if(!empty($host)){
            $this->_db = DB::getInstance();
        }
    }

    public function check($source, $items = array()) {
        foreach($items as $item => $rules) {
            foreach($rules as $rule => $rule_value) {

                $value = trim($source[$item]);
                $item = escape($item);

                if($rule === 'required' && empty($value)) {
                    $this->addError("{$item} is required");
                } else if(!empty($value)) {

你应该对http://www.minecraft.net/haspaid.jsp?user=xCodr的file_get_contents没有问题，因为它没有任何问题地响应 - 您可以在浏览器中尝试它。

因此，似乎您的服务器中存在阻止您的安全策略。也许SELinux？

如果您有SELinux，请尝试以下操作：

setsebool -P httpd_can_network_connect
