PHP如何删除字符串末尾和字符串开头的额外字符

Question

How can I get rid of extra hyphens at the end and beginning of user submitted text for example. I want visual-studio-2008 instead of -visual-studio-2008- is there a way I can remove the extra hyphens using PHP?

Answer 1

Just use trim and supply all characters you want to strip as the second parameter. In your case:

// Yields visual-studio-2008
$string = trim('-visual-studio-2008-' ,'-');
