Answer 1

刚好没事帮你写了这个
<?php
$arr1=array("a","b","c","d");
$arr2=array("2","3","4","5");
$arr3=array("a1","a3","a4","a4");
$count=count($arr1);
for($i=1;$i<=$count;$i++){
$tmp[$i]=array(array_shift($arr1),array_shift($arr2),array_shift($arr3));
}
print_r($tmp);
?>

Answer 2

$a1=array("a","b","c","d");
$a2=array("2","3","4","5");
$a3=array("a1","a3","a4","a4");
$a4=array();
foreach($a1 as $key=>$item){
$a4[$key][]=$item;
$a4[$key][]=$a2[$key];
$a4[$key][]=$a3[$key];
}
print_r($a4);
