[PHP] Help with str_replace()




Hi guys,

Can someone tell me why I am getting no output from the following file ...

Explanation:
I send a number (via procmail) to this script. This script in turn takes the
number ... opens up a file ... search for the previous number ... replace the
previous number with the new number ... and then writes it to the file ...

#!/usr/bin/php
<?php
while ( false !== ( $input = fgets ( STDIN ) ) )
	{
		$old_number = "/((NUMBER_ID=)([0-9]{1,6}))/" ;

		$new_number = "NUMBER_ID=".$input ;
						
		$number_file = "NumberRotation.conf" ;
						
		$file_contents = file_get_contents ( $number_file, FILE_USE_INCLUDE_PATH ) ;
		$file_contents = str_replace ( $old_number, $new_number, $file_contents ) ;
						
		file_put_contents ( $number_file, $file_contents ) ;
	}
?>

Thank You
Danny
