Insert an array to a specified location in named array - php

Question

In the array below, how can I push the new array into the $options array at the specified location?
$options = array (
array( "name" => "My Options",
"type" => "title"),
array( "type" => "open"),
array("name" => "Test",
"desc" => "Test",
"id" => $shortname."_theme",
"type" => "selectTemplate",
"options" => $mydir ),
//I want the pushed array inserted here.
array("name" => "Test2",
"desc" => "Test",
"id" => "test2",
"type" => "test",
"options" => $mydir ),
array( "type" => "close")
);
if(someCondition=="met")
{
array_push($options, array( "name" => "test",
"desc" => "description goes here",
"id" => "testMet",
"type" => "checkbox",
"std" => "true"));
}

Answer 1

You can use array_splice. For your example:
if($some_condition == 'met') {
// splice new option into array at position 3
array_splice($options, 3, 0, array($new_option));
}
Note: array_splice expects the last parameter to be an array of new elements, so for your example you need to pass an array containing the new option's array.

Answer 2

Simply
array_splice($options, 3, 0, $newArr);

Answer 3

for insert a new array, not to a spesific location(between $r[4] and $r[5]):
$options[]=array ("key" => "val"); //insert new array
$options[]=$v; //insert new variable
to insert a new array after spesific variable:
function array_push(&$array,$after_element_number,$new_var)
{
array_splice($array, $after_element_number, 0, $new_var);
}
if(someCondition=="met")
{
array_push($options, 2, array( "name" => "test",
"desc" => "description goes here",
"id" => "testMet",
"type" => "checkbox",
"std" => "true"));
}

Answer 4

As connec says, you can use array_splice, but without forgetting to wrap your array in another array, like this:
if ('met' === $some_condition)
{
array_splice($options, 3, 0, array(array(
'name' => 'test',
'desc' => 'description goes here',
'id' => 'testMet',
'type' => 'checkbox',
'std' => 'true'
)));
}
Edit: connec has already specified its response.
