Php exception handling
- 0 Comments
In normal desktop applications , we use exception handling everywhere in our
code.
But in server side script such as php, we can limit the usage of Exception handling.
Example for raising an exception in php
<?php
//create function with an exception
function checkValue($number)
{
if($number>4)
throw new
Exception(”Value must be 4 or below“);
return true
}
//trigger exception
checkValue(5);
?>
The above code will give : Fatal error: Uncaught exception ‘Exception’
If we call like this:
<?php
try{
checkValue(5);
}
catch(Exception $e)
{
echo ‘Message: ‘ .$e->getMessage();
}
?>
The code above will get an error like this:
Message: Value must be 4 or below
