示例

add_next_index_**
$arr[] = NULL;  add_next_index_null(arr);  
$arr[] = 42;    add_next_index_long(arr, 42);  
$arr[] = true;  add_next_index_bool(arr, 1);  
$arr[] = 3.14;  add_next_index_double(arr, 3.14);  
$arr[] = 'foo'; add_next_index_string(arr, "foo");  
$arr[] = $var;  add_next_index_zval(arr, zval);  

add_index_**
$arr[0] = NULL; add_index_null(arr, 0);  
$arr[1] = 42;       add_index_long(arr, 1, 42);  
$arr[2] = true;     add_index_bool(arr, 2, 1);  
$arr[3] = 3.14;     add_index_double(arr, 3, 3.14);  
$arr[4] = 'foo';        add_index_string(arr, 4, "foo", 1);  
$arr[5] = $var;     add_index_zval(arr, 5, zval);  

add_assoc_**
$arr["abc"] = NULL; add_assoc_null(arr, "abc");  
$arr["def"] = 42;   add_assoc_long(arr, "def", 42);  
$arr["ghi"] = true; add_assoc_bool(arr, "ghi", 1);  
$arr["jkl"]  = 3.14 add_assoc_double(arr, "jkl", 3.14);  
$arr["mno"]="foo"   add_assoc_string(arr, "mno", "foo", 1");  
$arr["pqr"] = $var; add_assoc_zval(arr, "pqr", zval);  

php代码

<?php
function array_test(){  
    $mystr = "Forty Five";  
    $return_value = array();  
    $return_value[42] = 123;  
    $return_value[] = "test";  
      
    $return_value[] = $mystr;  
    $return_value["double"] = 3.14;  
      
    $mysubarray;  
    $mysubarray = array();  
    $mysubarray[] = "hello";  
      
    $return_value["subarray"] = $mysubarray;  
  
    return $return_value;  
}  

扩展代码

PHP_FUNCTION(array_test){  
    char* mystr;  
    zval* mysubarray;  
  
    array_init(return_value);  
  
    add_index_long(return_value, 42, 123);  
  
    add_next_index_string(return_value, "test", 1);  
  
    add_next_index_stringl(return_value, "test_stringl", 10, 1);  
  
    mystr = estrdup("Forty Five");  
  
    add_next_index_string(return_value, mystr, 0);  
  
    add_assoc_double(return_value, "double", 3.14);  
  
    ALLOC_INIT_ZVAL(mysubarray);  
    array_init(mysubarray);  
    add_next_index_string(mysubarray, "hello", 1);  
    add_assoc_zval(return_value, "subarray", mysubarray);  
}
