For PHP regular expressions, find a regular expression to intercept strings:
For example, if I want to obtain the text in a text segment (without double quotation marks): "As of, this is some text, and this is some text ."
How to write a regular expression? I want to match "as of xxxxxxx ."

Reply to discussion (solution)

What is xxxx and where it matches

Preg_match_all ('~ As (.*?).~ ');, Just find the start and end mark.

What is xxxx and where it matches

Xxxx is omitted
For example, "This is a piece of text,". as of, my site hits reached 1 million. This is a piece of text ..." I want to retrieve "as of, my site hits reached 1 million times ." This section

$ S = 'this is a piece of text, as of, my site hits reached 1 million times. This is a piece of text... 'Preg _ match ('/as of (. + ?). /', $ S, $ m); echo $ m [0];

$ S = 'this is a piece of text, as of, my site hits reached 1 million times. This is a piece of text... 'Preg _ match ('/as of (. + ?). /', $ S, $ m); echo $ m [0];

Thank you very much!
