Using php regex to get value in javascript file

Question

I have tried the following code:

preg_match_all("/'<span> '+
'(.*?) Reviews/s", $data, $matches);

I am trying to get the number of reviews, here is a sample of the $data:

'<span> '+
'319 Reviews </span> '+
'</div> '+

My script is returning a $matches array empty - any ideas?

You can try this pattern:

/'<span> '\+\s*'\K[0-9]+(?= Reviews)/

\s is a character class for all spaces characters (including newlines)

\K means keep out and remove all on the left from match result

(?=...) is a lookahead that checks what is following without includes it in the match result.

What's about a new line?

@zerkms: the newline is matched with \s* and is optional, since it is not an important element of the javascript syntax here. (it is outside the string)

You could use the below regex which uses Dotall(s) modifier,

/'<span> '\+.\'\K\d+(?= Reviews)/s

OR

you could use a lookbehind with s modifier,

/(?<='<span> '\+.\')\d+(?= Reviews)/s
