使用 preg_replace 和 str_ireplace

Using preg_replace and str_ireplace

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;
}
?>

此代码正在修改我网站上显示的 URL。这是 URL 之一的副本:

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

我需要在上面的代码中更改什么才能从 URL 中删除 | 并删除 URL 末尾的 - ?任何帮助将不胜感激。

这样做就可以了:

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

示例:

<?
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;
}
?>

正则表达式解释:

(\||-$)


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 «$»
