php扩展开发之数组初始化及赋值

扩展中的C语言代码

PHP_FUNCTION(hello_array){
        char *mystr;
        zval *mysubarray;
        array_init(return_value); //初始化一个新数组
        add_index_long(return_value, 42, 123);//向数字索引的数组增加指定类型的值
        add_next_index_string(return_value, "I should now be found at index 43");
        add_next_index_stringl(return_value, "I'm at 44!", 10);
        mystr = estrdup("Forty Five");
        add_next_index_string(return_value, mystr);
        add_assoc_double(return_value, "pi", 3.1415926535);
}

php测试代码:

<?php
var_dump(hello_array());

输出结果:

[root@localhost hello]# php /root/php/hello.php
array(5) {
  [42]=>
  int(123)
  [43]=>
  string(33) "I should now be found at index 43"
  [44]=>
  string(10) "I'm at 44!"
  [45]=>
  string(10) "Forty Five"
  ["pi"]=>
  float(3.1415926535)
}
