Question

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网址。这是其中一个网址的副本：

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

我需要更改上述代码才能删除|以显示在网址中并删除网址末尾的-？任何帮助将不胜感激。

Answer 1

这样做：

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

使用preg_replace和str_ireplace
