PHP: The Right Way is an easy-to-read, quick reference for PHP popular coding standards, links to authoritative tutorials around the Web and what the contributors consider to be best practices at the present time. There is no canonical way to use PHP. This website aims to introduce new PHP developers to some topics which they may not discover until it is too late, and aims to give seasoned pros some fresh ideas on those topics they’ve been doing for years without ever reconsidering. This website will also not tell you which tools to use, but instead offer suggestions for multiple options, when possible explaining the differences in approach and use-case. This is a living document and will continue to be updated with more helpful information and examples as they become available. Translations PHP: The Right Way is translated into many different languages: English Bulgarian Chinese (Simplified) Chinese (Traditional) French German Indonesian Italian Japanese Korean Persian Polish Portuguese (Brazil) Romanian Russian Serbian Slovenian Spanish Thai Turkish Ukrainian العربية How to Contribute Help make this website the best resource for new PHP programmers!

worse than crap, it's craptastic. The core has almost no support at all for handling errors. Sure, PHP has a robust error reporting and logging system, but it has no real way of handling those errors. If you want to write robust code, you need to be able to actually handle errors. So how can we handle errors in PHP? What is an Error If we believe Merriam-Webster, the definition of an error is "an act that through ignorance, deficiency, or accident departs from or fails to achieve what should be done". So basically, it's when something (a piece of code) didn't do what it said it was going to do (for whatever reason). So for purposes of this post, I'm going to assert that there are 3 fundamental types of errors: Incidental Errors, Exceptional Errors and Application Errors. Incidental Errors These are errors in code that don't prevent the application from continuing on the current task. What I mean by that is that an incidental error is an error that should be noted, but doesn't really need to be handled since the task was still able to complete. Let's look at an example. if (strpos(‘foo', ‘bar', 5) !== false) { That code will throw a warning: Offset not contained in string. But the fact that the warning was thrown is irrelevant to the result of the function. Even though the offset isn't contained in the string, we know that the string ‘bar' is not in the string ‘foo' after the 5th position. So even though we got an error, we still get the correct result from the operation. Most notices are also incidental errors. It's important to note that incidental errors are not to be ignored. They do provide valuable debugging information and can provide clues to issues with application structure and code prior to discovering bugs. Therefore it's common that incidental errors are logged to a file (or displayed t
