復(fù)制代碼 代碼如下:

//二維數(shù)組去掉重復(fù)值
function array_unique_fb($array2D)
{
foreach ($array2D as $v)
{
$v = join(",",$v); //降維,也可以用implode,將一維數(shù)組轉(zhuǎn)換為用逗號連接的字符串
$temp[] = $v;
}
$temp = array_unique($temp); //去掉重復(fù)的字符串,也就是重復(fù)的一維數(shù)組
foreach ($temp as $k => $v)
{
$temp[$k] = explode(",",$v); //再將拆開的數(shù)組重新組裝
}
return $temp;
}

復(fù)制代碼 代碼如下:

//二維數(shù)組去掉重復(fù)值 并保留鍵值
function array_unique_fb($array2D)
{
foreach ($array2D as $k=>$v)
{
$v = join(",",$v); //降維,也可以用implode,將一維數(shù)組轉(zhuǎn)換為用逗號連接的字符串
$temp[$k] = $v;
}
$temp = array_unique($temp); //去掉重復(fù)的字符串,也就是重復(fù)的一維數(shù)組
foreach ($temp as $k => $v)
{
$array=explode(",",$v); //再將拆開的數(shù)組重新組裝
$temp2[$k]["id"] =$array[0];
$temp2[$k]["litpic"] =$array[1];
$temp2[$k]["title"] =$array[2];
$temp2[$k]["address"] =$array[3];
$temp2[$k]["starttime"] =$array[4];
$temp2[$k]["endtime"] =$array[5];
$temp2[$k]["classid"] =$array[6];
$temp2[$k]["ename"] =$array[7];
}
return $temp2;
