What do you use your Strings for? I know that for the past few articles we’ve looked at strings, but we never actually talked about them. A string is just a sequence of characters surrounded by quotes; strings in PHP are placed inside either single or double quotes. In other programming languages, like Java, strings are surrounded by double quotes and individual characters are surrounded by single quotes. <?php $string_1 = ‘This is an acceptable string’; $string_2 = “String with double quotes”; echo $string_1 . “<br>”; echo $string_2 . “<br>”; ?> You don’t have to store PHP Strings
