I needed a function to check user input, them feeding numbers to a form,
which represent an order of tasks.
Maybe one exists, I don't know. If it does, I couldn't find it.
Anyways, this is the simple function I came up with. Feed it an array and it will tell you
wether the array's keys follow up on eachother or not.
<?php
// Check if the array's keys follow up on eachother
function seqArray($aInput){
$bBool = true;
ksort($aInput);
for($i=1; $i<=count($aInput); $i++){
if(!isset($aInput[$i])){
$bBool = false;
}
}
return $bBool;
}
?>
