Answer 3

For a simple 'x' and "x" there is no real difference. The difference is with more complex strings. For instance double quotes can have curly braces for adding variables inside your string. "Welcome {$name} to our site" where as single quotes would need to be concatenated by the dot. 'Welcome ' . $name . ' to our site' There also other uses with strings that have quotes in them. Here are a couple examples:
$string ='He said "Welcome"';
$string = 'He said \'Welcome\'';
