**array_slice() Vs array_splice()**  

What arrayslice() function do: As name suggest this function just return part/slice of array which we pass to arrayslice() function as parameter 1 depending upon the parameter 2 and parameter 3.

For e.g : we have any array: $testarray=array("a","b","c","d","e","f","g","h"); $output=arrayslice($testarray,2,3); Parameter 1: Simply the array parameter 2: Index from where slicing of the $testarray array will start. Parameter3: Length Upto which we have to slice the $testarray array . The output of the above e.g will be:

For e.g arrayslice($testarray,3,2) As parameter 2 is +ve so we will start counting from left of $testarray upto 3rd index.As in $testarray at 3rd index value is 'd' .We will start counting from 'd' upto length = 2 (parameter 3) .So the output will be:

array{ [0]=>f [1]=>g }

arraysplice(): This function simply removes the part from the array which will be passed as parameter1 depending upon parameter2 and parameter3.

For e.g: $testarray=array("a","b","c","d","e","f","g","h");

arraysplice($testarray,2,5);

echo "

";


printr($testarray);


Output: array{
                  [0]=>a
                  [1]=>b
                  [2]=>h
                     }


Description:as parameter 2 is +ve so start counting from left end of array starting with 0 ,so at index 2 value is 'c' and as length is 5 so we will remove following elements:c,d,e,f,g so except this value remaining will be left in the $testarray array array
.
This function will directly make changes in $testarray .
If parameter 2 is +ve or _ve : This will work same as  arrayslice() explained above.
