PHP - 带双引号字符串的正则表达式

Question

I'm trying to use regular expressions to extract a certain value from a string:

"exec_hash": "/TPPE2ChB+5HuSHs84FBgx5/EgWi0OlaEXoXq4pq3Aukhc1Ypf0mZfKCJ10w=", "events_collector": "thiiM0ahsieSiech1phithe6chahngoo8sah6aid "

The data I want is the hash between the quotation marks. The problem is that there are multiple quotes within the string and preg_match_all function isn't returning the correct data. I've been playing around with regex for a while but can't figure it out. Ultimately, I'd like that data to be returned into a value. Ex: $string1 = '/TPPE2ChB+5HuSHs84FBgx5/EgWi0OlaEXoXq4pq3Aukhc1Ypf0mZfKCJ10w=';

Correction: I'm using curl to grab the page content. The data isn't stored in a variable.

$matches = array(); $thing = preg_match_all('/hash": "(.*?)", "events/',$page,$matches); print_r($matches);

It spits out a long array of much more than just the hash

Answer 1

Can you use substr?

haven't tested this, but in theory...

$pos_of_comma = strpos($str, ",");
if($pos_of_comma !== false) {
    $execHash = substr($str, 14, $pos_of_comma - 14);
}
