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}
20
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.
