Answer 1

array_insert($array,$pos,$val);
function array_insert($array,$pos,$val)
{
$array2 = array_splice($array,$pos);
$array[] = $val;
$array = array_merge($array,$array2);
return $array;
}

Answer 2

Try this:
$x = array(1,2,3,4,5);
$x = array_merge(array_slice($x, 0, 3), array(6), array_slice($x, 3));
print_r($x);
Output;
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 6
[4] => 4
[5] => 5
)

Answer 3

Use array_splice($array, $pos, 0, array($val)).

Answer 4

It can by done like this:
function array_insert_value(array $array = array(), $value = null, $position = null)
{
if(empty($position))
return array_merge($array, array($value));
else
return array_merge(
array_slice($array, 0, $position),
array($value),
array_slice($array, $position)
);
}

I cam up with this function. I have also included the code I used for testing I hope this helps.
function chngNdx($array,$ndex,$val){
$aCount = count($array);
for($x=($aCount)-1;$x>=$ndex;$x--){
$array[($x+1)] = $array[$x];
}
$array[$ndex] = $val;
return $array;
}
$aArray = array();
$aArray[0] = 1;
$aArray[1] = 2;
$aArray[2] = 3;
$aArray[3] = 4;
$aArray[4] = 5;
$ndex = 3; // # on the index to change 0-#
$val = 6;
print("before: ".print_r($aArray)."<br />");
$aArray = chngNdx($aArray,$ndex,$val);
print("after: ".print_r($aArray)."<br />");
