preg_match help

[jake2891]

Hi guys,

 

Can anyone see why my preg_match equation is not matching? basically trying to work out how equations work in regular expressions

 

<?php

if(preg_match('/1\+2=3/',3))

{

  $this->test = "your paramater matches.";

  echo $test;

}

?>

if(preg_match('/(.+?)3(.+?)/','1+2=3'))
{
   $this->test = "your paramater matches.";
   echo $test;
}

thanks for your reply. Although im passing the value 3 via the url. So would there be another way of doing it mathematically besides the following way below?

 

eg '/1\+2=3/' instead of '/3/'

 

if(preg_match('/3/',$this->getRequest()->getParameter('test'))) // test holds the value 3

{

  $this->test = "your paramater matches.";

  echo $test;

}
