PHP: make the cookies work globally on all subdomains

2 January 2013, in

To make cookies work globally on subdomains of a domain:

setcookie('CookieName', 'Value', time() + 3600, '/', '.mydomain.com');

Note: 
remember to use the dot (.) in '.mydomain.com' not 'mydomain.com'

CakePHP and MySQL tinyint datatype

21 September 2012, in

I observed that CakePHP treats tinyint fields as boolean (true/false) , but after investigation found that:

if you set the data type for a field to tinyint with length of 1, then CakePHP will treat it as boolean.

So I changed it to tinyint(2),

That's weird about CakePHP

How to delete entire directory which is not empty in PHP

8 May 2012, in

In PHP to delete a file we use unlink() function,

and to delete a directory we use rmdir() function but the directory has to be empty first

Here is how to delete the entire directory whether it has files or not

function delete_directory($path){

$d = dir($path);

while($entry = $d->read()) {

if ($entry!= "." && $entry!= "..") {

if(is_dir($path.'/'.$entry)){

delete_directory($path.'/'.$entry);

}

else{

unlink($path.'/'.$entry);

}

}

}

rmdir($path);

}
