Error type in php

There are three main error type in php

  1. Notice Error
  2. Warning Error
  3. Fatal Error
 

Notice Error

It is a simple and non critical error which is occur during script execution. It throw a error message but rest of code execute normally. This error generally occurs when you try to access the undefined variable.

<?php

$var="www.StudyZone4U.com";

echo $var1; // variable "$var1" is not define, so it throw a notice error

?>

Warning Error

It throw a warning error however rest of the script execute successfully. The main reason for warning errors are to include a missing file or using the incorrect number of parameters in a function.

<?php

echo "Warning Error!!";

include ("hello.php"); //if this file is not found then it will throw a warning error

?>

Fatal Error

It terminate the script execution when fatal error occurred. If you are trying to access the undefined functions, then the output is a fatal error.

<?php

function welcome()

{

echo "StudyZone4U.com";

}

hello(); // Function "hello()" is not defined.
         //It generate a fatal error and terminate the script execution.

?>
