A php function to remove duplicates from a two-dimensional array

//Function 1, two-dimensional array to remove duplicate values ​​
function array_unique_fb($array2D){
 foreach ($array2D as $v){
 $v = join( ",",$v); //For dimensionality reduction, you can also use implode to convert a one-dimensional array into a string connected with commas
 $temp[] = $v;
 }
 $temp = array_unique($temp) ; //Remove repeated strings, that is, repeated one-dimensional arrays
 foreach ($temp as $k => $v){
 $temp[$k] = explode(",",$v); / /Reassemble the disassembled array
 }
 return $temp;
}
//Function 2, two-dimensional array removes duplicate values ​​and retains key values
function array_unique_fb($array2D) {
 foreach ($array2D as $k=>$v){
 $v = join(",",$v); //For dimensionality reduction, you can also use implode to convert one-dimensional arrays into comma-connected ones String
 $temp[$k] = $v;
 }
 $temp = array_unique($temp); //Remove repeated strings, that is, repeated one-dimensional arrays
 foreach ($temp as $k => ; $v){
 $array=explode(",",$v); //Reassemble the disassembled array
 $temp2[$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;
}
?>

Call example:

$arr = array("a"=>array("a"=>"welcome","b"=>"to","c"=> "bbs.it-home.org"),
 "b"=>array("a"=>"Programmer's Home","b"=>"jbxue.com","c"=> ;"beijing")
 );
$arr2 = array_unique_fb($arr)
?>
