PHP_FUNCTION(print_array)
{
zval *z_array; //外部传入的数组
int count, i;
zval **z_item;
if (FAILURE == zend_parse_parameters(argc TSRMLS_CC, “a”, &z_array)) {

}
//获取数组大小
count = zend_hash_num_elements(Z_ARRVAL_P(z_array));
//将数组的内部指针指向第一个单元
zend_hash_internal_pointer_reset(Z_ARRVAL_P(z_array));
for (i = 0; i < count; i ++) {
char* key;
int idx;
//获取当前数据
zend_hash_get_current_data(Z_ARRVAL_P(z_array), (void**) &z_item);
convert_to_string_ex(z_item);
if (zend_hash_get_current_key(Z_ARRVAL_P(z_array), &key, &idx, 0) == HASH_KEY_IS_STRING) {
// KEY为字符串
php_printf(”array[%s] = %s”, key, Z_STRVAL_PP(z_item));
} else {
// KEY为数字
php_printf(”array[%d] = %s”, idx, Z_STRVAL_PP(z_item));
}
//将数组中的内部指针向前移动一位
zend_hash_move_forward(Z_ARRVAL_P(z_array));
}
}
在PHP调用如下：
$arr = array(
‘id’ => ‘ezdevelop’,
1 => “test number”,
2 => “test number 2″,
‘name’ => ‘Wenlong Wu’
);
print_array($arr);
?>
