function to check a multidimensional array if a given array is in the "haystack".
<?
$Example_Needle['Art'] = 'Verb';
$Example_Needle['Verbform']['Finitiv'] = 1;
$Example_Haystack[5] = 2;
$Example_Haystack[7] = 'nein';
$Example_Haystack['ID'] = 1;
$Example_Haystack['Art'] = 'Verb';
$Example_Haystack['Verbform']['Finitiv'] = 1;
$Example_Haystack['Zeitform']['Präsens'] = 'ja';
function is_in_array($Needle, $Haystack){
reset($Needle);
while(list($Key, $Value) = each($Needle)){
if(!array_key_exists($Key, $Haystack)){
return false;
}
if(!is_array($Value)){
if(in_array($Value, $Haystack)){
$Return = true;
}else{
return false;
}
}else{
if(is_in_array($Value, $Haystack[$Key])){
$Return = true;
}else{
return false;
}
}
}
return $Return;
}
if(is_in_array($Example_Needle, $Example_Haystack)){
echo 'yes';
}else{
echo 'no';
}
?>
This will emit "yes". The given needle must be an array. A string as the needle is not
supported in this function.
