I am trying to output the page title dynamically. I am using induces and this script is withing the header.php the goal is to output the header dynamically using a case/switch statement. here is my code:

<?php  $title ;
    switch($_SERVER['PHP_SELF'])  {
        case '/index.php': 
            $title = 'Home'; 
            break;
        case '/about.php': 
            $title = 'About'; 
            break;
        case '/services.php': 
            $title = 'Services'; 
            break;
        case '/portfolio.php': 
            $title = 'Portfolio'; 
            break;
        case '/staff.php': 
            $title = 'Staff'; 
            break;
        case '/contact.php': 
            $title = 'Contact us'; 
            break;
} ?>  <title><?php echo $title ?></title>

I am getting a error telling me my variable $title is not defined?

What i am doing wrong?

Solution 1:[1]

Try to define $title before switch:

$title = "";

Solution 2:[2]

in $_SERVER global array, $_SERVER[PHP_SELF] contains full path of file like

/project_name/index.php or /project_name/about.php or /project_name/services.php

Here project_name is name of your project.

replace 

 case '/index.php'
 case '/about.php'
 case '/services.php'
 ....

to 

 case '/project_name/index.php'
 case '/project_name/about.php'
 case '/project_name/services.php'
 .....

& also initialize $title in start of php file.

 <?php $title = ""; 

 switch ($_SERVER['PHP_SELF']) {
   case '/project_name/index.php':
     $title = 'Home'; 
     break;
  case '/project_name/about.php':
     $title = 'About';
     break;
  case '/project_name/services.php':
     $title = 'Services';
     break;
  case '/project_name/portfolio.php':
    $title = 'Portfolio';
    break;
 case '/project_name/staff.php':
    $title = 'Staff';
    break;
 case '/project_name/contact.php':
    $title = 'Contact us';
    break; 
 }
?>

for testing purposes

print_r($_SERVER);

and check for $_SERVER(PHP_SELF) value.

The code looks basically fine though you are missing a "default" block to catch anything that is not caught by any of the "case" statements.

Solution 4:[4]

though a beginner in php, i sorted this out on my own, and it is very simple and logical, consider title as string and it is initially empty one write on top $title = ""; when including header in home page just after inclusion write the value of title(reassigning value of variable)
