How to format number string in php like this-CodePudding

I want to customize my $number variable so that it will return like this 00:00:00

I want to insert ":" after every 2 numbers

Example:

$num = 120834;

So i want the output like this : 12:08:34

If you have always 8 digits, try this:

$num = '120466';
$new = substr($num, 0, 2) .':'. substr($num, 2, 2).':'. substr($num, 4, 2);

Or use implode();

$new = implode(":", str_split(strval($num), 2));

I think this is the most readable way:

You can use str_split() to separate it in an array based on the number of digits you want, 2 in this case.

$num = 120834;
$numParts = str_split($num, 2);

// then you can simply add it to a string
echo "$numParts[0]:$numParts[1]:$numParts[2]"; //12:08:34

Heres a function to do it easily for you:

//Then you can simply pass in the number you want to convert
function numberToTime($num)
{

    $numParts = str_split($num, 2);

    return "$numParts[0]:$numParts[1]:$numParts[2]";
}

You can also use chunk_split for this:

substr(chunk_split("120834", 2, ":"), 0, -1)
