        (
            [tags] => ,可乐鸡,
            [cate_id] => 3
        )
 
    [1] => Array
        (
            [tags] => ,红烧鱼,
            [cate_id] => 3
        )
 
    [2] => Array
        (
            [tags] => ,棒棒鸡,
            [cate_id] => 3
        )
 
    [3] => Array
        (

$arr = 第一个数组
foreach($arr as $tmp)
{
$tmp[0]=str_replace(",","",$tmp[0]);
}

楼上，还没明白的我意思

[zhang6464]

没测，应该是这个

$res=array();
foreach($arr as $v)
{
$str=substr($v[tags],1,-1);
if(strpos($str,',')){
$str=split(',',$);
foreach($str as $val)
$res[]=array('tags'=>$val,'cate_id'=>$v['cate_id']);
}
else
$res[]=array('tags'=>$v['tags'],'cate_id'=>$v['cate_id']);
}

抱歉，变量错了

$res=array();
foreach($arr as $v)
{
$str=substr($v[tags],1,-1);
if(strpos($str,',')){
$str=split(',',$str);
foreach($str as $val)
$res[]=array('tags'=>$val,'cate_id'=>$v['cate_id']);
}
else
$res[]=array('tags'=>$str,'cate_id'=>$v['cate_id']);
}

foreach($ar as $v) {
$t = split(',', trim($v['tags'], ','));
foreach($t as $v['tags']) {
$out[] = $v;
}
}
print_r($out);
