eval-stdin.php is a PHP script that comes bundled with PHPUnit. Its primary function is to read PHP code from standard input (stdin) and evaluate it. This utility is particularly useful when you need to execute PHP code dynamically during testing.

public function testEvalStdin() $code = 'return strlen("hello");'; $result = evalStdin::evaluate($code); $this->assertEquals(5, $result); eval-stdin
Suppose you want to test a simple PHP function using eval-stdin.php . You can pipe the PHP code into the utility like this:
In this example, the evalStdin.php utility is used to evaluate the PHP code and return the result, which is then asserted in the test. echo "<
Here's an example of using eval-stdin.php within a PHPUnit test:
By leveraging the eval-stdin.php utility, you can enhance your PHPUnit testing experience and write more dynamic, flexible tests. Here's an example of using eval-stdin
