README.md

Fast assert is a php extension that provides a nice way of making Assertions in php. It provides facilities for making various assertions using clean function-chaining syntax without having to pay any performance costs. For comparison, a functionally-equivalent version of Assert implemented in PHP is 150 times slower.

Examples

To assert that a value $a is an integer that is greater than 0:

Assert::argument()->is_integer($a)->is_true($a > 0);

If either assertion fails, this will throw an InvalidArgumentException.

To assert that an object is of a particular type:

Assert::received_value()->is_instance_of($obj, "MyDesiredClass");

If this assertion fails, this will throw an UnexpectedValueException.

See the documentation at docs/stubs/Assert.php for a full listing of Assert's methods.

Installation

First, you must build the extension with the following commands:

  • phpize
  • ./configure --enable-fast_assert
  • make
  • make test

Then, you can install it with:

  • sudo make install
  • Add the line extension=fast_assert.so to your php configuration file of choice. Your php.ini file should work, or you can try something like echo "extension=fast_assert.so" > /etc/php.d/fast_assert.ini
