php jsonp single quote escape, jsonp quote escape

The following format is generally used when jsonp output in php:

callbackname('json string');

If the middle json string contains single quotes, there is a problem with this output, and the caller generally cannot handle it, so we need to escape the single quotes.

If it is generated using json_encode, it can be escaped in the following way:

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

Here JSON_HEX_APOS is provided by php and replace the single quotes with u0027.

If it is string concatenation, you can use the following method:

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

Then output.
