Quick preg_replace question

[smith.james0]

Why doesn't this work?

 

$answer = "car bus train rabbit computer";

 

$search = array('rabbit', 'computer');

 

$answer2 =  preg_replace($search,"<font color=\"red\">$term</font>",$answer);

 

preg_replace is not case sensitve. rabbit or computer doesn't change colour?

 

Many thanks James

first, replace only works with single text, not with an array.

secondly, i dont believe the output will be wat you expected.

third, look up on strpos... O, i forgot how you spell it...

have you actually read the manual on preg_replace. here is a link: http://au2.php.net/preg_replace

preg_replace works with arrays.

 

$string = 'The quick brown fox jumped over the lazy dog.';

$patterns[0] = '/quick/';

$patterns[1] = '/brown/';

$patterns[2] = '/fox/';

$replacements[2] = 'bear';

$replacements[1] = 'black';

$replacements[0] = 'slow';

echo preg_replace($patterns, $replacements, $string);

 

 

I was adapting this.

Your terms in the arrays are not regular expressions and you don't reference the matches like that...
[code[
$answer = "car bus train rabbit computer";

$search = array('/(rabbit)/', '/(computer)/');

$answer2 =  preg_replace($search,'<font color="red">$1<font>',$answer);
?>

try yours like this then:

 

$answer = "car bus train rabbit computer";

$search = array("/rabbit/", "/computer/");

$answer2 =  preg_replace($search,"replacement in here",$answer);
