PHP扩展开发：如何测试和调试自定义函数？

Docker
Vagrant
Xdebug

<?php
use PHPUnit\Framework\TestCase;

class MyExtensionTest extends TestCase
{
    public function testMyFunction()
    {
        $result = my_function('input');
        $this->assertEquals('expected output', $result);
    }
}

zend_extension=xdebug.so
xdebug.remote_enable=1
xdebug.remote_host=localhost
xdebug.remote_port=9000

ZEND_FUNCTION(my_function)
{
    char *input;
    int input_len;

    ZEND_PARSE_PARAMETERS_START(1, 1)
        Z_PARAM_STRING(input, input_len)
    ZEND_PARSE_PARAMETERS_END();

    // 处理输入并生成输出

    RETURN_STRING(processed_output);
}

<?php
use PHPUnit\Framework\TestCase;

class MyExtensionTest extends TestCase
{
    public function testMyFunction()
    {
        $input = 'some input string';
        $expected = 'processed output';

        $result = my_function($input);

        $this->assertEquals($expected, $result);
    }
}

phpunit MyExtensionTest

php -dxdebug.remote_enable=1 -dxdebug.remote_host=localhost -dxdebug.remote_port=9000 index.php
