array_splice dynamically updates the total number of entries into the array. So for instance I had a case where I needed to insert a value into every 4th entry of the array from the back. The problem was when it added the first, because the total number was dynamically updated, it would only add after the 3rd then the 2nd and so one. The solution I found is to track the number of inserts which were done and account for them dynamically.
Code:
<?php
$modarray = array_reverse($mili);
$trig=1;
foreach($modarray as $rubber => $glue) {
if($rubber!="<BR>") {
$i++;
$b++;
if ($i==4) {
$trig++;
if($trig<=2) {
array_splice($modarray,$b,0,"<BR>");
}elseif($trig>=3){
array_splice($modarray,$b+($trig-2),0,"<BR>");
}
$i=0;
};
};
};
$fixarray = array_reverse($modarray);
?>
