put : after so many characters?

[android6011]

I'm just getting back into PHP and i feel stupid for asking, but I have a string that is YYYYddMM as a date, and I want to put a / inbetween the year, day, and month. what is the simplest way to do so?

[rofl90]

<?php

 

echo date("Y/d/m")

 

?>

 

If im wrong just escape the / with a \

im getting date from a file name, not the current date. I broke the date portion into a string so it looks like $date=yyyyddmm

you could use implode()

THANK YOU. that is what i have been trying to remember for like 30 minutes, i kept searching but couldnt find the function name

Before you can implode() you need the different parts separated in an array

 

<?php
$date='yyyyddmm';

$parts = sscanf ($date,'%4s%2s%2s');

echo implode ('/', $parts);
?>

[Psycho]

Or use preg_replace:

 

<?php

$date='yyyymmdd';

echo preg_replace('/(.{4})(.{2})(.{2})/', '$1/$2/$3', $date);

//output: yyyy/mm/dd

?>

 

You can change the order of the parts my modifying the second parameter
