so i just want to keep 'pppa','yyyyk','zzjjj' for the second_array,could anyone tell me how do that, please, thanks


$first_Array=('a','k','b','c','m','d','e','f','g')

$second_Array=('ahhh','kggg','bhjj','ctert','msd','dgx','efd','fffd','gdf','pppa','yyyyk','zzjjj')

Hi

$first=array('a','k','b','c','m','d','e','f','g');
$second=array('ahhh','kggg','bhjj','ctert','msd','dgx','efd','fffd','gdf','pppa'
,'yyyyk','zzjjj');
$third=array_filter($second,'hmm');

function hmm($one)
{
  global $first;
  return ! in_array(substr($one,0,1),$first);
}

thnaks, but it does not work for non english letter
like the following;
$first=array('?','?','?','?','?');
$second=array('?','?','?','?','?','??','??','??','??','??');

but you didn't ask that. it's unreasonable to expect someone to help you when you have not given them the full facts.

php5 unicode support is not great. but i suspect this variation on Feherke's script should work

mb_internal_encoding("UTF-8");
$first=array('?','?','?','?','?');
$second=array('?','?','?','?','?','??','??','??','??','??'); 
$third=array_filter($second,'hmm');

function hmm($one) {
  global $first;
  return ! in_array(mb_substr($one,0,1),$first);
}
