Let's say you have
<?php
$v=array("blue","blue","blue","blue");
if($v[0]==$v[1] && $v[1]==$v[2] && $v[2]==$v[3])
echo "Y"; else echo "N";//Y
?>
It works but the if-statement gets a bit messy if the number of array elements gets massive.
I find it is easier to use array_unique like so:
<?php
$v=array("blue","blue","blue","blue");
echo sizeof(array_unique($v))==1?"Y":"N";//Y
?>
