Question

php preg_replace and regex *.trim the fat*.

Asked by: www_puertoricoautoforo_com

Here's what I'm trying to do..

I'm trying to search sentences with preg_replace for a keyword and then replace the entire sentence with a GOOD or BAD value...

I was thinking of just using preg_replace but it's confusing me.. I'm trying to use a wildcard equivalent here but it's not working.

<?php
$string = 'Blah blah bloog goodinfo blargh blah blah';
$patterns[0] = '.* goodinfo .*';
$patterns[2] = '.* badinfo .*';
$replacements[0] = 'GOOD';
$replacements[1] = 'BAD';
echo preg_replace($patterns, $replacements, $string);
?>

Did you mean to put:

$patterns[1] = '.* badinfo .*';  ?

Regards,
Psyberion.

Sorry also you are missing the expression delimiters, try...

<?php
$string = 'Blah blah bloog goodinfo blargh blah blah';
$patterns[0] = '/.* goodinfo .*/';
$patterns[1] = '/.* badinfo .*/';
$replacements[0] = 'GOOD';
$replacements[1] = 'BAD';
echo preg_replace($patterns, $replacements, $string);
?>

GREAT, also can you please tell me how I can have multiple OR values for my patterns?

<?php
$string = 'These are fenders for your truck';
$patterns[0] = '/.* fenders .*/'||'/.* flares .*/';
$patterns[1] = '/.* hood .*/';
$replacements[0] = 'light weight';
$replacements[1] = 'heavy weight';
echo preg_replace($patterns, $replacements, $string);
?>

You should only have 1 set of / delimiters, so "/<pattern>/". So....

<?php
$string = 'These are fenders for your truck';
$patterns[0] = '/.* (fenders|flares) .*/';
$patterns[1] = '/.* hood .*/';
$replacements[0] = 'light weight';
$replacements[1] = 'heavy weight';
echo preg_replace($patterns, $replacements, $string);
?>
