php jsonp单引号转义_PHP

jsonp php

php中jsonp输出时一般用下面的格式:

代码如下:


callbackname('json string');

如果中间的json string中含有单引号,这个输出就是有问题的,调用方一般是无法处理的,所以我们要对单引号进行转义。

如果是用json_encode方式生成可以用下面的方式转义:

代码如下:


$ret = json_encode($result, JSON_HEX_APOS);
header('Content-Type: text/javascript; charset=utf-8');
echo $callback . '(\'' . $ret . '\');';

这里 JSON_HEX_APOS 是php是提供的把单引号换为 \u0027 了。

如果是字符串拼接的,可以用下面的方式:

代码如下:


$jsonData = preg_replace('/\'/', '\u0027', $jsonData);

然后再输出。
