$cars=array("ford","chevy");
$models=array("ford"=>array("ranger","escape"),"chevy"=>array("malibu"," tahoe"));
//Loop through first level of array, getting car maker
foreach($models as $carmaker=>$models) {
//Loop through car models, paring up with maker
foreach($models as $model) {
echo $carmaker.'-'.$model.'<br />';
}
}
Another option, which isn't as readable, is to use implode instead of the inner loop.
$cars=array("ford","chevy");
$models=array("ford"=>array("ranger","escape"),"chevy"=>array("malibu"," tahoe"));
foreach($models as $car=>$models) {
$pairing = $car.'-'.implode('<br />'.$car.'-',$models).'<br />';
echo $pairing;
}

Hello all,
What is the best way to do this? I have two arrays:
$cars=array("ford","chevy");
$models=array("ford"=>array("ranger","escape"),"chevy"=>array("malibu", "tahoe"));
then I need to traverse both arrays:
foreach ($cars as $car){ //now I need to get into the models array and echo out all of the models that //coincide with the specific car so it should print out ford-ranger //I basically want to do this but can't //how can I get into this second array without looping through the whole thing each time? foreach($cars[$car] as $model){
}
}
Thanks!
