Is there a php function similar to in_array that can detect if a "partial
value" is in an array value or not:

e.g.

$var1 = " big horse";    $var2 = " small yellow";    $var3 = " red hydrant";

$theArray = array(big blue horse, small yellow bird, giant red hydrant);

Is there a way to find out if $var1 in $theArray or $var2 etc.?

There's not a built in function, but it's not hard to write one:

function partial_in_array($needle, $haystack) {
 if (!is_array($needle)) { $needle = array($needle); }

 $needle = array_map('preg_quote', $needle);

 foreach ($needle as $pattern) {
   if (count(preg_grep("/$pattern/", $haystack)) > 0) return true;
 }

 return false;
}
