Error: An Error is an unexpected program result, which can not be handled by the program itself. That can be solved by using the issue in the code manually. An Error can be an infinite loop that can not be handled by the program itself so you have to manually repair that issue. There is an easy procedure to handle error i.e. using die() function.
Syntax:
die("message")
<?php
// Open file in read mode
$file_var = fopen("myfile.txt", "r");
// Check for file existence
if (!file_exists("myfile.txt")) {
die("Sorry Error!! file does not exists");
}
else {
fopen("myfile.txt", "r");
}
?>
try {
}
catch {
}
<?php
function valid_division($x, $y) {
if($y != 0) {
return true;
}
else {
throw new Exception("Why should not be equal to 0");
}
}
try {
valid_division(2, 0);
// Try block will only run if
// there is no exception
echo "Valid division";
}
catch(Exception $e) {
// Catch block will run if an
// exception occurs
echo "Error\n";
echo $e->getmessage();
}
?>
