?>

that easy, great thanks

is there easier way to do this, what troubles me if I make folders like this new1/new2/ if new1 dont exists i get error, I can branch only one folder not folder in folder in folder

<?php
$var1="sites";
$var2="files";
$var3="data";
$var4="test";

$v1=$var1;
$v2=$var1."/".$var2;
$v3=$var1."/".$var2."/".$var3;
$v4=$var1."/".$var2."/".$var3."/".$var4;

if (file_exists($v4)) { echo "Exists!";
}
elseif (file_exists($v3)) {
mkdir($v4, 0755);
}
elseif (file_exists($v2)) { 
mkdir($v3, 0755);
mkdir($v4, 0755);
}
elseif (file_exists($v1)) {
mkdir($v2, 0755);
mkdir($v3, 0755);
mkdir($v4, 0755);
}
else { 
mkdir($v1, 0755);
mkdir($v2, 0755);
mkdir($v3, 0755);
mkdir($v4, 0755);
}
?>

PHP:

 

Leaving off the if exists test...

<?php
$directory=array('sites','files','data','test');
$v='';
foreach($directory as $var)
{
  $v.=$var;
  mkdir($v,0755);
}
?>

Great! I was looking today at foreach but I didn't understud what exactly would be $var so I gave up
This is exactly what I was looking for, I can change arrays to make new1/new2/new3/new4 with / or make new folder branch without /
Thanks

<?php
$directory=array('sites','/files','/data','/test');
$v='';
foreach($directory as $var)
{
$v.=$var;
if (file_exists($v)) {}
else 
 {
 mkdir($v,0755);
 }
}
?>
