Errors in Php (Hindi)

How to Display Error Messages Using PHP | PHP Tutorial | Learn PHP Programming. In this PHP tutorial, you will learn how to show the user an error message using PHP, after they submit a form on your website. This is done by sending data back to the form using PHP validation. We will also cover how to keep the data in the form inputs, if the user is sent back with an error, so they don't need to re-type everything. PHP ERRORS A PHP Error occurs when something is wrong in the PHP code. The error can be as simple as a missing semicolon, or as complex as calling an incorrect variable. To efficiently resolve a PHP issue in a script, you must understand what kind of problem is occurring. The four types of PHP errors are: 1. Warning Error 2. Notice Error 3. Parse Error 4. Fatal Error Warning Error A warning error in PHP does not stop the script from running. It only warns you that there is a problem, one that is likely to cause bigger issues in the future. The most common causes of warning errors are: • 1- Calling on an external file that does not exist in the directory • 2- Wrong parameters in a function Notice Error Notice errors are minor errors. They are similar to warning errors, as they also don’t stop code execution. Often, the system is uncertain whether it’s an actual error or regular code. Notice errors usually occur if the script needs access to an undefined variable. Example: #errorsinphp #noticeerror #warningerror
