Trim leading white space with PHP?

由 可紊 提交于 2019-12-28 18:04:31
问题 There seems to be a bug in a Wordpress PHP function that leaves whitespace in front of the title of the page generated by <?php echo wp_title(''); ?> I've been through the Wordpress docs and forums on that function without any luck. I'm using it this way <body id="<?php echo wp_title(''); ?>"> in order to generate an HTML body tag with the id of the page title. So what I need to do is strip that white space, so that the body tag looks like this <body id="mypage"> instead of this <body id="

Automatically trimming an mp3 in PHP

由 ＊爱你＆永不变心＊ 提交于 2019-12-28 05:10:45
问题 Are there any ways to automatically trim an MP3 uploaded to a website to 30 seconds (or some other length) in PHP? If not, is there any good 3rd party services that could be integrated (transparently to the user) to achieve the same effect? Thanks. 回答1: You could try the MP3 Class on PHPClasses.
