I would use a combination of preg_replace and trim:
我会使用preg_replace和trim的组合：
trim(preg_replace('/-+/', '-', $str), '-')
The preg_replace call removes multiple dashes and trim removes the leading and trailing dashes.
preg_replace调用删除多个破折号，修剪删除前导和尾随破折号。

Without regular expression....
没有正则表达....
$string = trim($string,'-');
while (stristr($string,'--')) {$c = str_ireplace('--','-',$string);}
