如何删除查询字符串并只获取网址？ 12个答案

我是PHP和WordPress的新手，我需要使用WordPress函数download_URL（）从离岸网站导入图像。

我的问题是，我的网址看起来像这样：

HTTP：//www.test/img/FMR.jpg

但我也有这样的URL：

HTTP：//www.test/img/FMR.jpg Qq_0y12h

我可以删除.extension之后的所有内容吗？

你可以使用preg_replace，我为你做了这个小例子。

<?php $url = "http://www.test/img/FMR.jpg?Qq_0y12h"; echo "url = $url\n\n"; $urlFormatted = preg_replace("/\?.*$/", "", $url); echo "urlFormatted = $urlFormatted\n"; ?>

you can use preg_replace, I did this little example for you.

<?php $url = "http://www.test/img/FMR.jpg?Qq_0y12h"; echo "url = $url\n\n"; $urlFormatted = preg_replace("/\?.*$/", "", $url); echo "urlFormatted = $urlFormatted\n"; ?>从图片网址中删除字符[重复](Remove character from image url [duplicate])
