Array inserting

[rhyspaterson]

Hey guys,

 

Looking for a push in the right direction here. If i have an array like such:

 

$array[0] = olddata
$array[1] = olddata
$array[2] = olddata
$array[3] = olddata
$array[4] = olddata
$array[5] = olddata
$array[6] = olddata

 

and want to insert data in between on lines 1,2,3,4,5 <b>without</b> overwriting the data so my array looks like such:

 

$array[0] = olddata
$array[1] = newdata
$array[2] = newdata
$array[3] = newdata
$array[4] = newdata
$array[5] = newdata
$array[6] = olddata(used to be $array[1])
$array[6] = olddata(used to be $array[2])
$array[6] = olddata(used to be $array[3])
$array[6] = olddata(used to be $array[4])
$array[6] = olddata(used to be $array[5])

 

How would i go about it..? I'm basically pushing the other data down. The amount i will want to insert will be different every time and the lines i will want to insert the data into will be different every time. However on the upside the new data will always be straight after each other (ie insert new data on lines 2,3,4,5 and push old data down to 6,7,8,9 <b>not</b> insert on lines 2,4,9,6 ect..) So obviously i need some loopishly.. but just not sure where to start.. any suggestions..?

 

Thanks lads. You guys are saviors.

<?php
function insertArray($array, $addDataArr, $pos) {
    $newKey = -1;
    foreach ($array as $key => $val) {
          if ($key == $pos) { 
                foreach ($addDataArr as $val) {
                      $newArray[$key++] = $val;
                }
                $newKey = $key;     
          }else {
              if (isset($newKey) && $newKey != -1) {
                    $newArray[$newKey++] = $val;
              }else {
                    $newArray[$key] = $val;
              }
          }
    }
}
?>

 

Probably not the best way but I think it works, I also think there is something like www.php.net/array_merge

 

But yea, I think the above will work, untested.
