[Resolved] Double v. Single Quotes

[magic-chef]

When assigning values to variables what is the difference between using single and double quotes.

for example:

$var[] = 'name'

or

$var[]="name"

is one preferred over the other?

Generally speaking, there's not a lot of difference.

strings contained in ' chars are directly copied with no parsing, while strings contained in " chars are parsed for variables.

$var='abc';
$a = '$var';
print $a;
print "\n";
$a = "$var";
print $a;
print "\n";

In the above, the output on the command line is:

$var
abc

[magic-chef]

when assigning values to session vars which is the best method or does it not matter UNLESS you are assigning variables to the session and then you use the double quotes.

I'm asking because of a prior post where it was advised that I use " " v. ' ' to enclose a value which was not a variable.

If it's not a variable, there's no functional difference.
