$this->email->send() returns nothing

Looking at the email library function send(), I agree it should return only true or false. I wonder if your server or php version is not converting that to numeric 1/0 or text '1'/'0'.

Conditional, check for exact boolean, numeric or text output types

Code:

if( $this->email->send() === null )
{
die('send null');
}
if( $this->email->send() === true )
{
die('send true');
}
if( $this->email->send() === false )
{
die('send false');
}
if( $this->email->send() === 1 )
{
die('send one');
}
if( $this->email->send() === 0 )
{
die('send zero');
}
if( $this->email->send() === '1' )
{
die('send string one');
}
if( $this->email->send() === '0' )
{
die('send string zero');
}
