Php Extension: adding element to array property

Hi, I'm trying to write a php extension. I've created a class that contains a property which is an array. The class has one method to add elements to this property: Eg. $pt = new PhpTemplate();

    $pt->assign('name', 'Franky');

The above example must add a 'name' element to the tpl_vars property of the class PhpTemplate. When I debug the application in PHP I see that the element is added, but that no value is set. I use the following C++ code for the assign function: PHP_FUNCTION(phptemplate_assign) { if (ZEND_NUM_ARGS() != 2) {

    WRONG_PARAM_COUNT;

} char *str; int len; zval *var; if ( zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "sz/", &str, &len, &var) == FAILURE) {

    php_error(E_ERROR, "Invalid arguments for assign");
    RETURN_FALSE;

} zval **vars; if( zend_hash_find(HASH_OF(this_ptr),

                     "tpl_vars", 9, (void **)&vars) == SUCCESS)

{

    convert_to_array(*vars);
    add_assoc_zval(*vars, (char *) str, var);
    RETURN_TRUE;

} else {

    php_error(E_ERROR, "Invalid phpTemplate object");
    RETURN_FALSE;

} } Does anybody know what I'm doing wrong? Franky. -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/
