Answer 1

Its a short form of If-else, called ternary operator.
If the condition is true then code after ? mark will be executed, else code after : mark will be executed..

edit: Siavash Kardar Tehran
ex:
$var=(true)? "if true part ":"else part";
echo $var; //output : " if true part"

$var=(false)? "true part": "else part";
echo $var; // output : "else part "
