一个是curl的post请求函数,主要用于各平台api开发,进行请求接口的处理函数,如果你有多个平台,互相之间要传递数据,用这个函数绝对好用:

- /**
- * curl访问程序接口
- * @param string
- * @return array
- */
- function getCurlDate($url, $datas, $key) {
- $datas['time'] = $_SERVER['REQUEST_TIME'] + 300;
- $post_data['post'] = urlencode(authcode(serialize($datas), "ENCODE", $key));
- // echo $url;
- $ch = curl_init();
- curl_setopt($ch, CURLOPT_URL, $url);
- curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
- // 我们在POST数据哦!
- curl_setopt($ch, CURLOPT_POST, 1);
- // 把post的变量加上
- curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
- $output = curl_exec($ch);
- // dump(curl_error($ch));
- curl_close($ch);
- return json_decode($output, true);
- }
php获取文件的扩展名:

- * @$pic string 图片路径

- function get_file_ext($pic) {

还有一个是可逆的加密、解密函数(加密相同的字符串都会加密成不同的字符串的,非常好用)
