is_array ,echo(" ");

<?php

$useconfig=array('a'=>'1111','b'=>'2222','c'=>'3333','d'=>array('d1'=>'444','d2'=>'5555'));

foreach ($useconfig as $key => $val)

{

if (is_array($useconfig[$key]))

{ echo $key.'是数组:';

echo "<br />";

$useconfig2=$val;

foreach($useconfig2 as $key=>$val)

{

echo(" "); echo(" ");

echo $key.'=>'. $val;

echo "<br />";

}

}

else

{

echo $key.'=>'. $val;

echo "<br />";}

}

?>

结果:

a=>1111

b=>2222

c=>3333

d是数组:

d1=>444

d2=>5555
