in response to joshua dot patterson a+ plexus dot com above this, instead of using:
//////////////////////////////
$tCount = count($array);
for ($i=0;$i<$tCount;$i++)
{
Some Code
if ($someVar==4)
{
array_splice($array,$i,1);
$tCount--;
}
}
/////////////////////////////////
try using foreach as follows:
foreach($Array)
//this steps through each value that an array has in it.
{
Some Code
}
or even:
foreach($Array as $Key => $Value)
//$Key is equal to the array key number and $Value is
//equal to the value at $Key.
{
Some Code
}
im unsure of how it works with multi dimensional arrays or if it is faster but i would think it is.
