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. <?php
function inverse($x) {
if (!$x) {
throw new Exception('Division durch Null.');
}
return 1/$x;
}
try {
echo inverse(5) . "\n";
echo inverse(0) . "\n";
} catch (Exception $e) {
echo 'Exception abgefangen: ', $e->getMessage(), "\n";
}
// Ausführung fortsetzen
echo "Hallo Welt\n";
?>
try
{
// Some code...
}
catch(AError | BError $e)
{
// Handle exceptions
}
catch(Exception $e)
{
// Handle the general case
}<?php
function test() {
try {
throw new Exception('foo');
} catch (Exception $e) {
return 'catch';
} finally {
return 'finally';
}
}
echo test();
?>
