I'm using an API which is checking values with php preg_match method. I can only use original value (I can't prepare it) and regex expression. Value is a multiple line string like
12 value;
13 value;
14 value;
Now I need to check if every line matches my regex expression which is for single line would be like '/^\d+\s\w+\;$/'.
So the correct regex would return true (1) for the previous value and false (0) for the value below:
12 value;
13 ;
14 value;
Is that possible?
Include dotall modifier and then repeat the (current pattern + newline char at the start) zero or more times.
'/^\d+\h\w+;(?:\n\d+\h\w+;)*$/s'
In DOTALL mode, ^ matches the start of very first line. And $ matches the end of very last line. And also I replaced \s with \h because \s will match all the spaces and also the line breaks. Though \h will also match single space and a tab , for an exact thing, include space only instead of \h
/s modifier has no effect on your regex, since it contains no ..m modifier.
