note 92643 added to language.basic-syntax.phpmode

One aspect of PHP that you need to be careful of, is that ?> will drop you out of PHP code and into HTML even if it appears inside a // comment. (This does not apply to /* */ comments.) This can lead to unexpected results. For example, take this line: <?php $file_contents = '<?php die(); ?>' . "\n"; ?> If you try to remove it by turning it into a comment, you get this: <?php // $file_contents = '<?php die(); ?>' . "\n"; ?> Which results in ' . "\n"; (and whatever is in the lines following it) to be output to your HTML page. The cure is to either comment it out using /* */ tags, or re-write the line as: <?php $file_contents = '<' . '?php die(); ?' . '>' . "\n"; ?> ---- Server IP: 209.41.74.194 Probable Submitter: 67.165.168.203 ---- Manual Page -- http://www.php.net/manual/en/language.basic-syntax.phpmode.php Edit -- https://master.php.net/note/edit/92643 Del: integrated -- https://master.php.net/note/delete/92643/integrated Del: useless -- https://master.php.net/note/delete/92643/useless Del: bad code -- https://master.php.net/note/delete/92643/bad+code Del: spam -- https://master.php.net/note/delete/92643/spam Del: non-english -- https://master.php.net/note/delete/92643/non-english Del: in docs -- https://master.php.net/note/delete/92643/in+docs Del: other reasons-- https://master.php.net/note/delete/92643 Reject -- https://master.php.net/note/reject/92643 Search -- https://master.php.net/manage/user-notes.php
