本文介绍了如何在php中删除http,https和用户输入的斜杠的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
示例用户输入
http://domain.com/
http://domain.com/ topic /
http://domain.com/topic/cars/
http://www.domain.com/topic/questions/
我想要一个php函数来使输出成为像
域.com
domain.com/topic/
domain.com/topic/cars/
www.domain.com/topic/questions/
让我知道: 一系列不允许的词汇并使用 strpos
和 str_replace
将其从传入的URL中动态移除:
function remove_http($ url ){
$ disallowed = array('http://','https://');
foreach($不允许为$ d){
if(strpos($ url,$ d)=== 0){
return str_replace($ d,'',$ url);
}
}
return $ url;
}
Example user input
http://domain.com/
http://domain.com/topic/
http://domain.com/topic/cars/
http://www.domain.com/topic/questions/
I want a php function to make the output like
domain.com
domain.com/topic/
domain.com/topic/cars/
www.domain.com/topic/questions/
Let me know :)
解决方案
You should use an array of "disallowed" terms and use strpos
and str_replace
to dynamically remove them from the passed-in URL:
function remove_http($url) {
$disallowed = array('http://', 'https://');
foreach($disallowed as $d) {
if(strpos($url, $d) === 0) {
return str_replace($d, '', $url);
}
}
return $url;
}
