How to replace "\" using str_replace() in PHP?
提问by user1759682
I would like to remove all back slashes from strings on my site. I do not wish to use strip_slashes(), because I want to keep forward slashes.
我想从我网站上的字符串中删除所有反斜杠。我不想使用strip_slashes()，因为我想保留正斜杠。
This is the code I am trying:
这是我正在尝试的代码：
echo str_replace("\", "", "it\'s Tuesday!");
I want to find the backslash in any given string and remove it. But, this code is not working right.
我想在任何给定的字符串中找到反斜杠并将其删除。但是，此代码无法正常工作。
Error:
错误：
syntax error, unexpected T_CONSTANT_ENCAPSED_STRING
What could I be doing wrong?
我可能做错了什么？

The backslash is actually escaping the closing quote in your string.
反斜杠实际上是在转义字符串中的结束引号。
Try echo str_replace("\\","","it\'s Tuesday!");
尝试 echo str_replace("\\","","it\'s Tuesday!");

No sure why you are using str_replaceto remove \use
不知道你为什么要使用str_replace删除\使用
echo stripslashes("it\'s Tuesday!");
But if its just an example then
但如果它只是一个例子那么
echo str_replace("\","","it\'s Tuesday!");
Please Note that stripslashesonly remove backslashes not forward
请注意，stripslashes只删除反斜杠而不是向前
echo stripslashes("it\'s \ \ // Tuesday!");
Outputs
输出
it's // Tuesday!

Try and get the result:
尝试并得到结果：
$str = "it\'s Tuesday!";
$remove_slash = stripslashes($str);
print_r($remove_slash);
Output: it's Tuesday!
输出：今天是星期二！

From the stripslashes()documentation:
从stripslashes()文档：
Returns a string with backslashesstripped off. (\' becomes ' and so on.) Double backslashes (\\) are made into a single backslash (\).
返回一个去掉反斜杠的字符串。（\' 变成 ' 等等。）双反斜杠 (\\) 变成一个反斜杠 (\)。
So you shouldn't worry about the fwd. slashes.
所以你不应该担心 fwd。斜线。

echo str_replace("\'", "'", "it\'s Tuesday!");
// It's Tuesday!
