POPHP Zend Engine Extension static method call
text
Body
copied!<p>I am writing a PHP extension. From the C code I try to invoke a static method in PHP code. </p> <p>The PHP-method looks like this:</p> <pre><code><?php class Model { static method GetModelById($id) { ... } } ?> </code></pre> <p>The call in C looks like this:</p> <pre><code>if( call_user_function_ex( &((*ce)->function_table), NULL, &fname, &retval_ptr, 1, func_params, 0, NULL TSRMLS_CC ) == SUCCESS ){ // do some stuff here ... } </code></pre> <p>... where all passed parameters should contain proper values. The strange thing here is: if I compile my extension against php 5.2 the code works fine, if I compile this against php 5.3, the method call fails with no error message.</p> <p>I also tried <code>zend_call_method</code> with no success in either version.</p> <p>Can anyone give a tip for me? How would you call a static method from C?</p> <p>Thanks in advance!</p> <p><strong>Edit</strong></p> <p>Sorry guys, I got it working via <code>zend_call_method</code> like so:</p> <pre><code>if( zend_call_method( NULL, *ce, NULL, "getmodelbyid", strlen("getmodelbyid"), &retval_ptr, 1, p1, NULL TSRMLS_CC ) == FAILURE) { php_printf("gosh!"); } else { php_printf("yep!"); } </code></pre> <p>... so I learned:</p> <ol> <li>Function names must always be in lowercase</li> <li>You better have a look at PHP's source code when it comes to string lengths (<code>zend_call_method</code> adds +1 internally).</li> </ol> <p>Although I am new to C, I think the PHP code base is over-compilcated in many ways!</p> <p>Hope this helps someone else!</p>
