| Hi, It may look there is no difference between single qutoes and double quotes when you use them for example to display some simple text: echo "Abcde"; // will return Abcde echo 'Abcde'; // will return Abcde But you can find differences when you are using quotes for example in relation to some variables: $value = 123; echo "Abcde $value"; // will return Abcde 123 echo 'Abcde $value'; // will return Abcde $value In some cases the usage of single or double quotes may be faster. Using single quotes for simple displaying of text can be faster than using double quotes: echo 'Abcde'; // can be faster echo "Abcde"; But using of double quotes in relation to some variable may be faster: $value = 123; echo "Abcde $value"; // can be faster echo 'Abcde ' . $value; | |||||||||||
