使用preg_replace和str_ireplace

Here's a copy of my current code:

这是我当前代码的副本:

<?
function smarty_modifier_url(&$url) {

    //remove html tags
    $url = strip_tags($url);

    trim($url);
    $url = preg_replace ( '%[.,:\'"/\\\\[\]{}\%\-_!?]%simx', ' ', $url );
    $url = str_ireplace ( " ", "-", $url );
    return $url;
}
?>

This code is modifying URLs that are shown on my website. Here's a copy of one of the URLs:

此代码正在修改我网站上显示的URL。以下是其中一个网址的副本:

http://example.com/listing/1/Testing-|-See-If-This-Works-

What would I need to change in the code above to remove | from showing in URLs and to remove the - at the end of the URL? Any help would be appreciated.

我需要在上面的代码中更改以删除|从URL中显示并删除 - 在URL的末尾?任何帮助,将不胜感激。

This will do it:

这样做:

$url = preg_replace('/(\||-$)/', '', $url );

Example:

<?
function smarty_modifier_url(&$url) {

    //remove html tags
    $url = strip_tags($url);

    trim($url);
    $url = preg_replace ( '%[.,:\'"/\\\\[\]{}\%\-_!?]%simx', ' ', $url );
    $url = str_replace ( " ", "-", $url );
    $url = preg_replace('/(\||-$)/', '', $url );
    $url = preg_replace('/[-]{2,}/', '-', $url);
    return $url;
}
?>

Regex explanation:

(\||-$)


Match the regex below and capture its match into backreference number 1 «(\||-$)»
   Match this alternative «\|»
      Match the character “|” literally «\|»
   Or match this alternative «-$»
      Match the character “-” literally «-»
      Assert position at the end of the string, or before the line break at the end of the string, if any «$»
