Hi.
My boolean function returns true, if all values in array are that same type (like this - it's
checking, if all are numeric).
<?php
function isNumArray($array)
{
$r = false;
if (is_array($array))
{
foreach($array as $n=>$v)
{
if (is_array( $array[$n] ))
{
$r = isNumArray( $array[$n] );
if ($r==false) break;
} else
if (!is_numeric($v))
{
$r=false;
break;
} else
$r=true;
}
}
return $r;
}
# example
$arr1 = array('34', 3.14, array('321', 092), '2', 55, -173,
array('1.98', '-044'), '0');
$arr2 = array('3 4', 3.14, array('-321', 56, 0-92), '2', 55, true,
array('zero44'), '0');
echo '1. '.(isNumArray($arr1) ? 'Only numz.' : 'Various
values!')."\r\n".
'2. '.(isNumArray($arr2) ? 'Only numz.' : 'Various values!');
# return
# 1. Only numz.
# 2. Various values!
