Convert a flat array to a delimited string [duplicate]

There is a simple function called implode.

$string = implode(';', $array);

You should use the implode function.

For example, implode(' ',$tags); will place a space between each item in the array.

If any one do not want to use implode so you can also use following function:

function my_implode($separator,$array){
   $temp = '';


   foreach($array as $key=>$item){
       $temp .=  $item; 
       if($key != sizeof($array)-1){
            $temp .= $separator  ; 
       }
   }//end of the foreach loop

   return $temp;
}//end of the function

$array = array("One", "Two", "Three","Four");


$str = my_implode('-',$array);
echo $str;

There is also an function join which is an alias of implode.

Using implode

$array_items = ['one','two','three','four']; 
$string_from_array = implode(',', $array_items);

echo $string_from_array;
//output: one,two,three,four

Using join (alias of implode)

$array_items = ['one','two','three','four']; 
$string_from_array = join(',', $array_items);

echo $string_from_array;
//output: one,two,three,four
