PHP: Remove third item in 4 items comma list "1,2,3,4"

Question

How can I delete the 3 in "1,2,3,4"?

Dirty hack: Slice the sliced arrays and join them again.

$s = "1,2,3,4";

$array = explode(',', $s);
$a = array_splice($array, 0, -2);
$b = array_splice($array, 1, 1);
$s = implode(',', $a).','.implode($b);

echo $s; // 1,2,4

OK. How about using strpos and instr? Find the second comma and the third one.

Sorry, no. I dunno the values. People use dummy strings ;) – Martin Jan 03 '14 at 22:06

$s = "1,2,3,4";
$array = explode(',', $s); 
unset($array[2]);
$Arr = array_values($array); 
print_r($Arr);

How about this, by this you do not depend on the position of the string rather can wipe out by value.

$s = "1,2,3,4";
$array = explode(",",$s);
$val = 3 ;
$key = array_search($val,$array);
if($key!==false){
    unset($array[$key]);
}

echo implode(",",$array); // 1,2,4
