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;
}
