PHP preg_match直到双线中断

Question

I have this data in a mysql field:

First text text text text
 text text text text
 text text text text text text
 text text text text text text

Second text text text text
 text text text text
 text text text text text text
 text text text text text text

I'm trying to preg match from the first word until the double line break. I've tried:

preg_match('/First(.*)

/', $mysqlrow, $m);

This returns no rows. I've also tried the m and s modifiers, which don't return the proper string. I've also tried which doesn't return anything.

How do you do this

Answer 1

You need the s modifier and you also need to change your wildcard quantifier to be non-greedy:

preg_match('/First(.*?)

/s', $mysqlrow, $m);

The s option will cause the . wildcard to match and the non-greedy will cause the * wildcard to not eat up all the it runs across before matching .

You can also optionally match the just in case you have that in your database:

preg_match('/First(.*?)?
?
/s', $mysqlrow, $m);
