废话不多说了，直接给大家贴代码了，具体代码如下所示：

<?php $GLOBALS['count'] = 0; //校验data或者content的json格式是否有错误 function data($value) { if (isset($value['data'])) { $value['data'] = json_decode($value['data'], true); } else if (isset($value['content'])) { $value['content'] = json_decode($value['content'], true); } else { die('必须要有content或者data字段'); } $error = json_last_error(); if (!empty($error)) { echo "<pre>"; print_r($value); echo "</pre>"; } return $value; } //校验静态资源是否存在； function my_filter($value) { $needle = ['.jpg', '.jpeg', '.png', '.avi', '.mp4', '.wav', '.gif', '.mp3']; $root = 'D:/phpStudy/WWW/levelData/'; foreach ($needle as $k => $v) { $aa = strpos($value, $v); if ($aa) { $file = $root . $value; if (!file_exists($file)) { $GLOBALS['count']++; return $value; } } } } //获取多维数组里面某一列的下标，并重新组成一维数组 function searchMultiArray(array $array, $search, $mode = 'key') { $res = array(); foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $key => $value) { if ($search === ${${"mode"}}) { if ($mode == 'key') { $res[] = $value; } else { $res[] = $key; } } } return $res; } function my_filter_answer($value) { $needle = ['，', '、', ' ', '.', ',,', '，，']; foreach ($needle as $k => $v) { $aa = strpos($value, $v); if ($aa) { return 1; } } } //将汉字，特殊字符原样变成json数据 function ch_json_encode($data) { $ret = ch_urlencode($data); $ret = json_encode($ret); return '\'' . addslashes(urldecode($ret)) . '\''; } //汉字，特殊字符变可读懂的字符串主程序 function ch_urlencode($data) { if (is_array($data) || is_object($data)) { foreach ($data as $k => $v) { if (is_scalar($v)) { if (is_array($data)) { $data[$k] = urlencode($v); } else if (is_object($data)) { $data->$k = urlencode($v); } } else if (is_array($data)) { $data[$k] = ch_urlencode($v); // 递归调用该函数 } else if (is_object($data)) { $data->$k = ch_urlencode($v); } } } return $data; }
