echo $a;

In this example variable $a assigned a string . But a php error is semi colon ( ; )  sign is not used after end on the string “This is the string” . When you save this code and run on web browser ,web browser seems blank and nothing will happen .

In this condition error reporting helps to find errors in php code .
