PHP two-dimensional array deduplication Function

PHP array RemovalRepeated itemsThere is a built-in FunctionArray_unique(), But the array_unique function of PHP is only applicable to one-dimensional arrays and does not apply to multi-dimensional arrays. The following providesTwo-dimensional arrayArray_unique Function

 // Remove duplicate values from two-dimensional arrays 
 Function Array_unique_fb (  $ Array2d  )  { 
 Foreach   (  $ Array2d   As   $ V  )  { 
 $ V   =   Join  (  ","  ,  $ V  )  ;    // Dimensionality reduction. You can also use implode to convert a one-dimensional array to a string connected with commas (,). 
 $ Temp  [  ]   =   $ V  ; 
} 
 $ Temp   =   Array_unique  (  $ Temp  )  ;      // Remove the duplicate string, that is, the duplicate one-dimensional array. 
 Foreach   (  $ Temp   As   $ K   =>     $ V )  { 
 $ Temp  [  $ K  ]   =   Explode  (  ","  ,  $ V  )  ;     // Re-assemble the split Array 
 } 
 Return  $ Temp  ; 
 }


// Remove duplicate values from the two-dimensional array and retain the key value
Function array_unique_fb ($ array2d ){
Foreach ($ array2d as $ k => $ v ){

$ Temp [$ K] = $ V;
}
$ Temp = array_unique ($ temp); // remove the duplicate string, that is, the duplicate one-dimensional array.
Foreach ($ temp as $ k => $ v ){
$ Array = explode (",", $ V); // re-assemble the split Array
$ Temp2 [$ K] ["ID"] = $ array [0];
