问题 I'm trying to use str_replace to replace all iframes with my own content. I believe I can use regular expression but not exactly sure how to remove all content within the iframe tag.

问题 One of our pages pulls content from a database table using the following code: <?php echo $project['description']; ?> What I need is for all < and > instances to be replaced with < and > respectively. Can you help modify the above code to include a preg_replace statement (or str_replace() )? 回答1: <?php echo htmlspecialchars_decode($project['description']); ?> Should get you what you need. If you are ONLY looking to decode those, though, then: <?php echo str_replace("<","<",str_replace(">",">"
