Help With an Error

[xdentan]

Hi, can you help me rewrite this to not give a warning

Code:

<?php
$variable = "test";
if (preg_match("/" + $variable + "/", "testing")) {
   echo "A match was found.";
} else {
   echo "A match was not found.";
}
?> 

Result:
Warning: Delimiter must not be alphanumeric or backslash in /var/www/html/test.php on line 3
A match was not found.

As far as I can see that should work: you're using a forward slash as your delimiter, and that is neither alphanumeric nor a backslash.

But if what you've shown is what you're doing, why not just use [man]strpos[/man]? It would be a lot faster.

what are the + signs for?

to me it looks like your trying to concatenate the string, javascript style.

in php you use . to concatenate

<?php
$variable = "test";
if (preg_match("/" . $variable . "/", "testing")) {
   echo "A match was found.";
} else {
   echo "A match was not found.";
}


// or just

$variable = "test";
if (preg_match("/$variable/", "testing")) {
   echo "A match was found.";
} else {
   echo "A match was not found.";
}
?>
