1Try catch comes under exception handeling concept where using this we control the runtime error and modify the message as we want.
2
3// function created with exception throw
4function checkdata($number){
5 if($number > 10){
6 throw new Exception("Number is greater than 10");
7 }
8 return true;
9}
10
11// try block starts
12try{
13 checkdata(15);
14 echo "The number is below 10";
15}
16// catch block
17catch(Exception $e){
18 echo "Message :".$e->getMessage();
19}

21In above code if condition is not satisfied then it will throw exception and which gets caught by catch block and show the error message.
