These errors can be prevented to a very large degree by careful programming. External Errors: These are errors related to the interactions with the world outside your code (e.g., failing to opening a file or database, the network connection dropping, being unable to load a certain PHP module, etc.). These errors will always occur, but their impact can be mitigated. The better you prepare your code for these external errors, by assuming as little as possible when your code is executing, the less these errors will negatively affect your program.Ways to Deal with PHP ErrorsOnce errors occur and we detect them, there are four fundamental ways to deal with them: Display the Error: This allows the error to be shown to the developer and/or user when the program is being

If you would handle errors properly then it may lead to many unforeseen consequences. Its very simple in PHP to handle an errors. Using die() function While writing your PHP program you should check all possible error condition before going ahead and take appropriate action when required. Try following example without having /tmp/test.xt file and with this file. This way you can write an efficient code. Using above technique you can stop your program whenever it errors out and display more meaningful and user friendly message. Defining Custom Error Handling Function You can write your own function to handling any error. PHP provides you a framework to define error handling function. This function must be able to handle a minimum of two parameters (error level and error message) but can accept up to five parameters (optionally: file, line-number
