php mysql try catch code example

Example 1: php try catch

<?php

function test() {
    try {
        throw new Exception('foo');
    } catch (Exception $e) {
        return 'catch';
    } finally {
        return 'finally';
    }
}

echo test();
?>

Example 2: try catch in php

Try catch comes under exception handeling concept where using this we control the runtime error and modify the message as we want.

// function created with exception throw
function checkdata($number){
	if($number > 10){
    	throw new Exception("Number is greater than 10");
    }
    return true;
}

// try block starts
try{
	checkdata(15);
  	echo "The number is below 10";
}
// catch block
catch(Exception $e){
	echo "Message :".$e->getMessage();
}

In above code if condition is not satisfied then it will throw exception and which gets caught by catch block and show the error message.
