One should know error handling in programs to become an effective PHP developer. PHP training can give the learner the best knowledge of error handling through practical learning methods conducted in PHP classes under the guidance of experts.
PHP or Hypertext Preprocessor is a popular server-side scripting technology used for building dynamic websites. Just as the programs developed in any other programming language, bugs or errors may arise in PHP programs too and to handle them one should have good knowledge of how these errors arise and what are the effective ways to handle them. In order to be a successful PHP developer, one should have good command over errors and error handling. Hence, joining PHP training course at a good PHP coaching institute would be a better way to get knowledge of the programming language. One can learn error handling in programs in a much effective way through practical learning conducted in PHP classes under the guidance of experts.
The first requirement of a developer to debug the programs is to understand the cause of the errors. The better is the understanding of the error cause, the lesser would be the time required to fix the errors by the developer. The errors in PHP are usually of three types – syntactical, logical; and run time errors.

Apart from these there are a few other errors that are usually seen arising out of PHP programs like
Error Handling in PHP
Errors can be handled easily in PHP with the help of following techniques.
For example:
<?php
@include (‘script_name.php’); //in case you do not want to see the “division by zero” error
$num = @ ($x/$y);
?>
For Example:
<?php
if (isset($_POST[‘var_name’])){
$var_name1 = $_POST[‘var_name’];
}
else{
echo “Did not get the data for var_name”;
}
?>
In the above program the condition if() will be executed if the POST method receives appropriate value and if it does not receive the value then the statement in else will be displayed making the user clearly understand about the error.
For Example:
<?php
if (isset($_POST[‘Name’])) {
trigger_error(‘You must add a number not the name’);
}
?>
This way one can clearly understand the where the errors are arising in the program and hence, can easily handle the errors in shorter time duration. To get this understanding of programming in a better way, one should join PHP training classes in order to get hands-on programming experience under the guidance of experts who can guide the learners about errors and ways to solve them.
