php Method for merging the same elements in an array

This article illustrates how php combines the same elements in an array. Share it for your reference. The details are as follows:

We have introduced N methods about deleting repeated arrays. Today's example is a little different, that is, deleting the same elements in the array, leaving only one same element. The specific example code is as follows:

<?php

//  Delete the same elements in the array, leaving only the 1 Same element 

function formatArray($array)

{

sort($array);

$tem = "";

$temarray = array();

$j = 0;

for($i=0;$i<count($array);$i++)

{

if($array[$i]!=$tem)

{

$temarray[$j] = $array[$i];

$j++;

}

$tem = $array[$i];

}

return $temarray;

}

// Test   Call function 

$array = array('aa','bb','aa',3,4,5,5,5,5,'bc');

$arr = formatArray($array);

print_r($arr);

?>

I hope this article is helpful to everyone's php programming.
