preg_match help needed.

bliss · 03-20-2007, 09:43 AM

PHP Code:

      $match_expression = '<br><span class\=a>(.*)\/<\/span><\/font>';

    preg_match($match_expression,$total,$matches); 

    return strip_tags($matches[1]);

Quote:

Warning: preg_match() [function.preg-match]: Unknown modifier '<' in /home/website/public_html/directory/myscript.php on line 21

Is giving me an error. Why? I did not think you had to escape < and > operators.

Try this:

PHP Code:

  $match_expression = '/<br><span class\=a>(.*)/<\/span><\/font>/'; 

    preg_match($match_expression,$total,$matches);  

    return strip_tags($matches[1]);

Remember that you have to escape the characters ^.[$()|*+?{\ (if you want to 'match' the character and not use their function) with a backslash everytime

.

Dismounted: No, what was I missing was not one of those. It was the escape on the / and the /i at the very end, but yes that is always great to know.
