Arrays in strings

Very often you will want to use an array directly inside a string using code something like this:

<?php

      $myarray['foo'] = "bar";

      print "This is from an array: $myarray['foo']\n";
 ?>

Sadly, that won't work - PHP will consider $myarray to be a variable by itself and consider the ['foo'] part as a normal string that it should tack on to the end of the value of $myarray. The way around this is to use braces { and } around the variable, which is how you tell PHP that you are passing it an array to read from. This next snippet is the right way to do things:

<?php

      $myarray['foo'] = "bar";

      print "This is from an array: {$myarray['foo']}\n";
 ?>
