Newbie problems with zend API?

Question

PHP

When working with zval in the function, there is no way to find the string index in the input array using the zend_hash_find function. Brief listing:

PHP_FUNCTION(test){
    HashTable *array1;
    zval **value1;
    char *key1 = "one";
    if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "H", &array1) == FAILURE) {
       RETURN_NULL();
    }
    if(zend_hash_find(array1, key1, strlen(key1), (void **)&value1) == FAILURE) {
       RETURN_BOOL(0);
    }
    RETURN_BOOL(1); 
 }

The function always returns false, even when the input array has the string key "one".
Thanks in advance for any insight

Answer 1

Missed an error. instead of strlen(key1), you need strlen(key1) +1. Otherwise, the end-of-line character '\0' is ignored

Answer 2

Try to localize the problem by selecting other functions with different parameters, try with PHP too

Answer 3

The code is working, apparently in the function, in user space, incorrect data is being transferred
<?php
$arr = array('one' => 10, abc => 30, 'two' => 40 );
var_dump(test($arr)); // bool(true)
?>
