preg_match_all 匹配太多
我不知道要在正则表达式中添加什么以使其仅匹配“精确”模式。 #users/(.+?)/# 与此字符串 users/john/someweirdstuff/ 将匹配。
我得到 'john' 而不是 'john/someweirdstuff' （这是朝着正确方向迈出的一步），但我根本不希望它匹配。因为字符串（应该是 URL）不一样。
所以基本上，我应该在我的 reg exp 后面添加什么来使它说“最后一个斜杠之后不应该有任何内容”
I don't know what to add to my regular expression to make it only match the 'exact' patterns.#users/(.+?)/# with this string users/john/someweirdstuff/ will be a match.
I am getting 'john' and not 'john/someweirdstuff' (which is a good step in the right direction), but I don't want it to match at all. Because the string (which are supposed to be URLs) aren't the same.
So basically, what do I add behind my reg exp to make it say "there should nothing after the last slash"

您应该使用与字符串结尾匹配的
$字符。您还应该避免匹配“任何字符 (
.)”，而应该匹配“任何不是斜杠的字符 ([^/])”。如示例所示 注意，我省略了问号（
？），本例中的问号将字符匹配从贪婪（尽可能多地匹配）更改为惰性（尽可能少地匹配）。另请 就像这样：
You should use the
$character that matches the end of the string.You should also avoid matching "any character (
.)" and you should match "any character which is not a slash ([^/]). As shown in the example).Also note I omitted the question mark (
?), the question mark in this instance changes the character matching from greedy (match as much as possible) to lazy (match as few as possible).Use it like so:
如果你想说“最后一个斜杠之后不应该有任何内容”，请说“字符串在最后一个斜杠之后结束”，即
#users/(.+)/$#。省略问号也应该起作用，使加号“贪婪”，即尽可能多地匹配。If you want to say "there should be nothing after the last slash", say "the string ends after the last slash", i.e.
#users/(.+)/$#. Ommitting the question mark should also work, making the plus sign "greedy", i.e. matching as much as it can.
