catch in php code example

Example 1: try catch php

function inverso($x) {
    if (!$x) {
        throw new Exception('Zero division.');
    }
    return 1/$x;
}

try {
    echo inverso(5) . "\n";
    echo inverso(0) . "\n";
} catch (Exception $e) {
    echo 'and the error is: ',  $e->getMessage(), "\n";
}

Example 2: try catch php

try {
}
catch(Exception $e) {
}

Example 3: 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.
