Strings within single quotes are not evaluated. String within double quotes are. Try this example: <? $foo = 'bar'; echo '$foo'; echo "$foo"; echo $foo; echo 'bar'; echo "bar"; ?> If there is nothing to be evaluated (such as a variable), as is the case in the last two examples, you will notice no difference. Also, because single quotes within a string must be escaped when single quotes are the delimiter, and vice versa, it is sometimes convenient to choose based on that alone. For example: $sql = "select foo from bar where blah='whatever'"; instead of: $sql = 'select foo from bar where blah=\'whatever\''; or: echo '<a href="http://www.php.net/";>PHP</a>'; instead of: echo "<a href=\"http://www.php.net/\";>PHP</a>"; Hope that helps.
