数组的数据类型是上面这样的，我想根据type的值筛选出数据，比如type=4,那么久只要所有type=4的数据，请问用PHP怎么写？
$a = array(
'BL001'=>array('A14257','B17548'),
'CDF002'=>array('A14257','C48751'),
'FGE453'=>array('DF5533','GR6445','GH5544'),
'GEN001'=>array('NT7532','DE9342','C48751'),
);
$b = array('A14257','E453T4','Y64344','FG4809','C48751','H4443R');
foreach($a as $k=>$v){
$t = array_intersect ($v, $b);
if($t){
$c[$k] = $t;
}
}
print_r($c);
?>
$res=array (
0 => array('id' =>'76',
'title' =>'gf',
'type' =>'4' ,
'update_time' =>'1433814812',
'status' =>'1' ,
'view' =>'0',
'category_id' =>'2' ,
'model_id' =>'2',
'pid' =>'0'),
1 => array('id' =>'75',
'title' =>'骑士妙招破死局' ,
'type' =>'1',
'update_time' =>'1433758503',
'status' =>'1' ,
'view' =>'0' ,
'category_id' =>'2',
'model_id' =>'2',
'pid' =>'0'),
2 =>array('id' =>'74',
'title' =>'职场新人要学会的4件事',
'type' =>'5',
'update_time' =>'1433757936',
'status' =>'1',
'view' =>'0',
'category_id' =>'2',
'model_id' =>'2',
'pid' =>'0'),
3 =>array('id' =>'73',
'title' =>'职场新人该如何看待繁琐的工作',
'type' =>'5',
'update_time' =>'1433757902',
'status' =>'0',
'view' =>'0',
'category_id' =>'2',
'model_id' =>'2',
'pid' =>'0'));
$tot=count($res);
for($i=0;$i<$tot;$i++)
{
if($res[$i]['type']=='5')
{
foreach($res[$i] as $a)
{
echo("<div>".$a."</div>");
}
}
}
?>追问
数据格式还是要和原来的一样
你的没有
php本来就是一个数据类型转换功能很强的语言，它有很强的类型隐式转换的功能
