PHP if statement?

Question

Hi i wonder what i might be doing wrong. I have two conditions that returns true or false.For same reason it doesnt work. I would appreciate if someone point out what i might be doing wrong.

<?php  
  $pagetype = strpos($currentPage, 'retail');
  if(isset($quoterequest) && $pagetype === True && $currentPage !== 'index.php'){
    echo "this is retail" ;
  }elseif(isset($quoterequest) && $pagetype === False && $currentPage !== 'index.php'){
    echo "this is restaurant";
  }                               
?>

EDIT- Sorry i edit it but didnt show up for some reason. Basically script looks into urls for term "retail" if it finds it, it should return "this is retail" if not "this is restaurant"

quoterequest is a just a variable like so

$quoterequest = "washington"

and the currentpage is driven from

<?php $currentPage = basename($_SERVER['SCRIPT_NAME']);

Just to be clear. Url is structure like so

www.example.com/retail-store.php www.example.com/store.php

$pageType is never true. If the string is contained, strpos returns an integer. So test for !== false.

<?php  
    $pagetype = strpos($currentPage, 'retail');
    if (isset($quoterequest) && $currentPage !== 'index.php') {
        if ($pagetype !== false) {
            echo "this is retail";
        }
        else {
            echo "this is restaurant";
        }
    }                     
?>

no sense in duplicating the conditions each time either. The below code should do what you want.. (taking into account the aforementioned strpos comments).

$pagetype = strpos($currentPage, 'retail');
if($currentPage !== 'index.php' && isset($quoterequest)){
   if ($pagetype === false){
     echo "restaurant";
   }else{
     echo "retail"; 
   }
}

PHP has lazy evaluation. If the first term in an if statement evaluates to false, it will stop evaluating the rest of the code. If isset($quoterequest) evaluates to false, nothing else in either of your statements will be examined.

$>
<?php

function untrue() {
        return FALSE;
}

function truth() {
        echo "called " . __FUNCTION__ . "\n!";
        return TRUE;
}

if ( untrue() && truth() ){
        echo "Strict.\n";
} else {
        echo "Lazy!\n";
}

$> php test.php
Lazy!
