Removing unwanted data between 2 points

I'm trying to remove data would text files on the fly from text files using preg_replace:

The cat that looks like a tiger is possessed.

Code (markup):

and I want to use preg_replace() to make it looke like:

The cat is possessed.

Code (markup):

I would like to use the preg_replace() but other ideas would proably be helpful too.

 

I think preg_replace is OK to use here.
Maybe you can try something like :

<?php
$string = 'The cat that looks like a tiger is possessed.';
$pattern = '/that looks like a tiger /';
$replacement = '';
$new_string = preg_replace($pattern, $replacement, $string);
echo $new_string;
?>

PHP:

or, maybe a str_replace can be useful too...
i.e.

$phrase  = "You should eat fruits, vegetables, and fiber every day.";
$healthy = array("fruits", "vegetables", "fiber");
$yummy   = array("pizza", "beer", "ice cream");

$newphrase = str_replace($healthy, $yummy, $phrase);
// will output : You should eat pizza, beer, and ice cream every day
