On php v 5.3.6 it's correctly works
Example 1 (Error):
PHP_FUNCTION(test_parse_parameters) {
char *p_str1 = NULL;
char *p_str2 = NULL;
int p_long;
int p_str1_len;
int p_str2_len;
if (FAILURE == zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "sls",
&p_str1, &p_str1_len, &p_long, &p_str2, &p_str2_len)) {
return;
}
zend_error(E_WARNING, "First parameter: '%s' and it len: %d", p_str1,
p_str1_len);
zend_error(E_WARNING, "Second parameter: '%d'", p_long);
zend_error(E_WARNING, "Third parameter: '%s' and it len: %d", p_str2,
p_str2_len);
}
Run:
[antonio@antonio]# php -r 'test_parse_parameters("first", 123, "third");'
