Quick Reference
The PHP Exception() constructor is used to create an Exception object and set some of its properties.
<?php
function divide($dividend, $divisor) {
if($divisor == 0) {
throw new Exception('Division by zero', 1);
}
return $dividend / $divisor;
}
try {
echo divide(9, 0);
}
catch(Exception $exeption) {
$code = $exeption->getCode();
$message = $exeption->getMessage();
$file = $exeption->getFile();
$line = $exeption->getLine();
echo "Exception thrown in $file on line $line: [Code $code]
$message";
}
?>
Output
Exception thrown in /home/test.php on line 8: [Code 1] Division by zero

PHP NOTES:
- When using PHP, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
