An important note concerning assert in PHP earlier than 7. Unlike other languages with an assert construct, PHP doesn't throw assert statements out entirely - it treats it as a function (do a debug_backtrace() in a function called by an assertion). Turning asserts off seems to just hotwire the function into doing nothing in the engine. Posted on January 18, 2018by dams. PHP assertions and their usage. PHP has a clever native debugging tool : the PHP assertions. In a nutshell, assertions are a functioncall to assert(), that triggers an error when a condition is not satisfied.

ASSERT_QUIET_EVAL only works if assert() is called on a string; cf. . It seems to me that the documentation has to be improved, and also that ASSERT_QUIET_EVAL (and maybe other assert_options) should have been deprecated in PHP 7.2 (where calling assert() with a string argument) has been deprecated).

This assertion will return true in the case if the array contains the provided value else return false and in case of true the asserted test case got passed else test case got failed. This library contains efficient assertions to test the input and output of your methods. With these assertions, you can greatly reduce the amount of coding needed to write a safe implementation. All assertions in the Assert class throw an Webmozart\Assert\InvalidArgumentException if they fail. Join Stack Overflow to learn, share knowledge, and build your career.

If the assertion is given as a string it will be evaluated as PHP code by assert() .

In PHP 7.0, the assert statement received some enhancements. Notably, it added the ability to throw exceptions on failures (but off by ini default) and the code to assert could now be directly given to assert, instead of only through a string argument. phpunit documentation: Assert an Object is an Instance of a Class.
