There's not too much of a difference. Most people prefer using double quotes because of the fact that you can do this: <?php $var2 = "Look at {$var1}!"; ?> which you can't do the {} thing with single quotes. You would have to do <?php $var = 'Look at '.$var1.'!'; ?>
in PHP, using double quotes (") you can still use variables in the string. This is considerably slower than using single quotes (')
example:
echo "Hello $name";
in programming, single quotes are for characters, and double quotes are for string, but in php, javascript, html, css i don't see any difference between the two.
There isn't an immediate difference in comfort between a single and double pillow top, but you are able to flip double pillow top mattresses. This can make it more comfortable in the long run and may help it last longer. Double pillow tops do tend to be more expensive than single ones.

You can use single quotes $variable = 'string'; You can use double quotes $variable = "string"; You can use the Heredoc method $variable = <<<EOT Very Long String EOT; And you can use the Nowdoc method (after PHP 5.3.0) $variable = <<<'EOT' Very Long String EOT;
A single house is otherwise known as a detached house. A double house is a semi-detached house. Semi detached houses have one shared built wall whereas a detached has space all around it..

Yes, you can use both single quotes (' ') and double quotes (" ") for defining strings in PHP. However, the choice between single and double quotes depends on whether you need to include variables or special characters within the string. Single quotes treat everything as a literal string, while double quotes allow for variable interpolation and escape sequences.
The literals with single quotes are Characters and can have a width of only one. Ex: 'y' or 'a' etc Strings cannot be declared using single quotes. They have to be declared with double quotes.
Double quotes allow changes to the text string, including: -- substitution for variable names, such as $x; -- expansion of special characters, such as '*' or '?' within file names; -- command execution within backticks, such as "You have `ls | wc -l` files" Single quotes enclose an explict string, and prevent most of these changes.
