Question

I have a big string with html:

$html = '...hello{"text":"52"},{"text":" watching"}world...';

I want to search in $html with:

{"text":"*"},{"text":" watching"}

So I can get the number (where the asterisk is)? In my example, it is 52 , but it can be any number.

I should end up with $number equal 52 . Is regex the appropriate route?

Answer 1

You can try (?<=\{"text":")(\d+)(?="\},\{"text":" watching"\})

With:

• (?<=\{"text":") : the positive lookbehind you're looking for (belongs to {"text":" )
• (\d+) : the digits you need (belongs to * )
• (?="\},\{"text":" watching"\}) : the positive lookahead you're looking for (belongs to "},{"text":" watching"} )
