I have the following string:
window['test'] = false;
window['options'] = true;
window['data'] = { "id" : 2345, "stuff": [{"id":704,"name":"test"};`
How would I go about extracting the JSON data in window['data']? The example data I provided is just a small sample of what really exists. There could be more data before and/or after window['data'].
I've tried this but had no luck:
preg_match( '#window["test"] = (.*?);\s*$#m', $html, $matches );
分享 There are several issues that I can see.
Your string uses single quotes: window['test'] not window["test"], which you have in your regular expression. This means you should use double quotes to enclose your regular expression (or escape the quotes).
Your regular expression has unescaped brackets, which is used to create a character class. You should use \[ instead of just [.
You say you are looking for data but your regular expression looks for test.
You have a $ at the end of the regular expression, which means you won't match if there is nothing other than whitespace after the bit you matched.
Also your data seems incomplete, there are some missing brackets at the end, but I think that is just a copy-paste error.
So I would try:
php > preg_match("#window\['data'\]\s*=\s*(.*?);#", $html, $matches);
php > print_r($matches);
Array
(
[0] => window['data'] = {"id":2345,"stuff":[{"id":704,"name":"test"};
[1] => {"id":2345,"stuff":[{"id":704,"name":"test"}
)
Of course then you must use json_decode() to convert the JSON string ($matches[1]) into an object or associative array that you can use.
