问题 I would appreciate an answer to settle a disagreement between me and some co-workers. We have a typical PHP / LAMP web application. The only input we want from users is plain text. We do not invite or want users to enter HTML at any point. Form elements are mostly basic input text tags. There might be a few textareas, checkboxes etc. There is currently no sanitizing of output to pages. All dynamic content, some of which came from user input, is simply echoed to the page. We obviously need to

For the purposes of this function, the charsets ISO

问题 I've migrated my site from interspire CMS to Joomla! CMS. I've managed to migrate all the database of articles, but some of them have a weird issue - when I access the page from joomla, the title contains HTML entities like ’ . As you can guess from the CMS's I use, I rely on PHP as my server side, and MySql for my database. I tried to go over the titles of the articles in the database with htmlspecialchars_decode AND html_entity_decode in order to get rid of those, but it had no effect. if I

问题 Using both htmlspecialchars and htmlentities is causing blank outputs from items such as a ™ symbol and even single ' quotes.

Any reason why this is occuring? here is the code that is causing the problem: <p> <?php echo nl2br(htmlspecialchars($aboutarray[0]['about_us'], ENT_COMPAT, "UTF-8")); ?> </p> 回答1: That string is not encoded in valid UTF-8 encoding.

问题 I have strings like: Avery® Laser & Inkjet Self-Adhesive I need to convert them to Avery Laser & Inkjet Self-Adhesive.
