[英]How to get words starting with # and remove from string
$query = "Hello #world What's #up"
$newquery = "Hello, What's"
所以基本上我不希望删除#
开头的单词。
尝试这个:
$query = "Hello #world What's #up";
$newquery = preg_replace('/#[^\s]+/', '', $query);
echo $newquery;
使用preg_replace() 。
$newquery = preg_replace('/#[^\s]+/', '', $query);
