在我的一个PHP站点上，我使用此正则表达式自动从字符串中删除电话号码：
$text = preg_replace('/'+?[0-9][0-9()-'s+]{4,20}[0-9]/', '[removed]', $text);
但是，当用户发布包含多个数字作为其文本一部分的长 URL 时，URL 也会受到 preg_replace 的影响，这会破坏 URL。
如何确保上述preg_replace不会更改$text中包含的 URL？
编辑：
根据要求，下面是上述preg_replace破坏 URL 的示例：
$text = 'Please help me with my question here: https://stackoverflow.com/questions/20589314/ Thanks!';
$text = preg_replace('/'+?[0-9][0-9()-'s+]{4,20}[0-9]/', '[removed]', $text);
echo $text;
//echoes: Please help me with my question here: https://stackoverflow.com/questions/[removed]/ Thanks!
我认为您必须解析网址和电话号码，例如/(?: url 'K | phone number)/ - sln
@sln：我该怎么做？如果有帮助，这里有一个URL正则表达式：stackoverflow.com/a/8234912/869849 - ProgrammerGirl
下面是一个使用提供的 url 和电话编号正则表达式的示例：

$str = preg_replace_callback('~((?:(?:[a-zA-Z]{3,9}:(?://)?)(?:[;:&=+$,'w-]+@)?[a-zA-Z0-9.-]+|(?:www'.|[;:&=+$,'w-]+@)[a-zA-Z0-9.-]+)(?:(?:/[+'~%/.'w-]*)?'??[+=&;%@.'w-]*'#?'w*)?)|('+?[0-9][0-9()'s+-]{4,20}[0-9])~',
function( $matches ){
if ( $matches[1] != "" ) {
return $matches[1];
}
return '[removed]';
},
$text);
print $str;
输出>>

正则表达式，使用 RegexFormat 处理
# '~((?:(?:[a-zA-Z]{3,9}:(?://)?)(?:[;:&=+$,'w-]+@)?[a-zA-Z0-9.-]+|(?:www'.|[;:&=+$,'w-]+@)[a-zA-Z0-9.-]+)(?:(?:/[+'~%/.'w-]*)?'??[+=&;%@.'w-]*'#?'w*)?)|('+?[0-9][0-9()'s+-]{4,20}[0-9])~'
( # (1 start), URL

你应该多做一些编码，所以与其抚摸你的头，不如去抚摸你的自我！

假设电话号码前面经常有空格或位于一行的开头是否公平？如果是这样，这将阻止您意外更改 URL，因为 URL 中间既不存在空格也不存在换行符：
$text = preg_replace('/(^|'s)'+?[0-9][0-9()-'s+]{4,20}[0-9]/', '[removed]', $text);
