ereg to variable

[csousley]

$qid = "901";
$word_map = "901(2), 327(1), 520(8)";

$word_map_word_pulled = ereg($qid."\([0-9]+\)", $word_map);

echo "<b> $word_map_word_pulled </b>";

This code returns a 1 in the echo statement, saying it found 1 match. Sounds good. Is there any way I can set a variable to "901(2)" instead of 1. I want a variable of the actual result found, not how many are found.

Any thoughts? Thanks!

Two things ...

1) You need to escape parenthesis in any regular expression as they are part of the syntax.
2) Use the third optional argument to ereg() to get the match.

Try this to see what I mean ...

$qid = "901"; 
$word_map = "901(2), 327(1), 520(8)"; 

$word_map_word_pulled = ereg($qid."\([0-9]+\)", $word_map, $regs); 

echo "<b>".$regs[1]."</b>";

The call to ereg should be ...

$word_map_word_pulled = ereg($qid."([0-9]+)", $word_map);

For some reason, the escape backslashes got left out on my last post.
