I am trying to build a function for easier array manipulation in my project.
I want to do it by passing reference. Hoping to be more productive and resource-saving way.
function add_element ($element=array(),&$data) {
if(!empty($data)) {
$data += $element;
}
return true;
}
// $element can be array('one','two') or array('color'=>'blue','type'=>'card')
I am not experienced with references, thanks for any tip.
I believe that this will have the effect that you're looking for. We are passing in the original array as the reference and it adds whatever data you pass to it to the original array.
function add_element (&$original_array = array(), $data) {
// Cast an array if it isn't already
!is_array($data) ? (array)$data : null;
if(!empty($data)) {
$original_array = $original_array + $data;
}
return true;
}
$names_array = array("first_name" => "bob");
$data_to_add = array("second_name" => "fred");
// Add new variable
add_element($names_array, $data_to_add);
// Show the contents
print_r($names_array);

However, I have just taken what you posted as a starting point there. The above is basically the same as the following, which requires no special function:
$names_array = array("first_name" => "bob");
$data_to_add = array("second_name" => "fred");
// Add new variable
$names_array = $names_array + $data_to_add;
// Show the contents
print_r($names_array);

add_element($create_variable,$elements); it should create it as well :) So here is the line: isset($data) || $data = array();Try
array_push($data, $element);
The array_push function add a new data to the end of the array.
Check the details here: http://php.net/manual/de/function.array-push.php
function add_element($element=array(), &$data) {
if(!empty($element) && !empty($data)) {
$data = array_merge($data, $element);
}
return true;
}
$test = array(0=>'zero');
add_element(array(1=>'one'), $test);
print_r($test);
What about using :
$data[] = $element;
instead of
$data += $element;
(assuming you can't use array_push).
$data[] = $element; and $data[] = array() are not the same thing!add_element($add,$data); and move, I don't want to do $data = add_element($add,$data);. that's why ı want to use reference. @Alexandre N.$arr = array('0'=>'zero','1'=>'one','2'=>'two'); I need to add $element = array('21'=>'twentyone','45'=>'fourthy-five'); When array_push($arr,$element); It creates extra index [3] [3]=>array([21]... I need [2]=>two,[21]=>twentyone...
