Note Submitter: Anonymous ---- This example provides a great opportunity to emphasize the newline issue as it relates to HTML rendering. <?php $a_bool = TRUE; // a boolean $a_str = "foo"; // a string $a_str2 = 'foo'; // a string $an_int = 12; // an integer echo 'a_bool is a '; echo gettype($a_bool); echo '<br>'; echo 'a_str is a '; echo gettype($a_str); // prints out: string echo '<br>'; echo 'an_int is a '; echo gettype($an_int); // prints out: string echo '<br>'; // If this is an integer, increment it by four if (is_int($an_int)) { $an_int += 4; echo "<br>integer: $an_int"; } // If $bool is a string, print it out // (does not print out anything) if (is_string($a_bool)) { echo "String: $a_bool"; } ?>
