How about insert rather than double? It's more generic
and double is simple if you have insert.
Like this:
<?php
$test = array(1,2,3,5);
array_insert($test, 3, 4);
print_r($test);
?>
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )

I'd like to propose two new array functions. I currently have the following
implementation of del() and double() in PHP, but IMHO it would be better to have these
(or atleast del()) natively in PHP.
When using unset($array[$index]) on array, no re-indexing is performed:
<?php
$test = array(1,2,3,4,5,6);
unset($test[2]);
print_r($test);
?>
Array ( [0] => 1 [1] => 2 [3] => 4 [4] => 5 [5] => 6 )
The del() method in the floowing code re-indexes the array:
<?php
class ftk_array {
var $data;
function ftk_array($data=array()) {
$this->data=$data;
}
function del($pos) {
for($i=$pos+1;$i<count($this->data);$i++) {
$this->data[($i-1)]=$this->data[$i];
}
unset($this->data[count($this->data)-1]);
}
function double($pos) {
for($i=count($this->data);$i>$pos;$i--) {
$this->data[($i)]=$this->data[$i-1];
}
}
}
$test=new ftk_array(array(1,2,3,4,5,6));
$test->del(1);
$test->double(4);
print_r($test->data);
?>
The double() method creates a clone of a given array element, while it maintainsthe
indexes as well.
