str_replace（'\\“'，''，$ str）不在服务器上工作原因？

Question

I am using

str_replace('\"','',$str); 

to replace the '\\"' from php script. Its correctly working on localhost .

When uploading its not working on server. Why ?

The script is like, $str=http://www.keralatourism.org/beta-images/Newsletter.jpg\\""> To remove the \\" using echo str_replace('\\"','',$str);

Its working on local host but not in live server

Answer 1

the double quote does not need to be escaped unless it's wrapped in double quotes. str_replace('"','',$str); or str_replace("\\"",'',$str);

if you want to find the back slash as well I believe you would have to escape it with another back slash.

str_replace('\\\\"','',$str); or str_replace("\\\\"",'',$str);

if you want to find " instead of " then you need to change the " " to " PHP sees these as different.

Answer 2

I am not completely clear but if you want to remove backslashes just user stripslashes

 $str= 'http://www.keralatourism.org/beta-images/Newsletter.jpg\""';
 echo stripslashes($str);

If you are trying to remove the double quotes:

$str= 'http://www.keralatourism.org/beta-images/Newsletter.jpg\""';
echo str_replace ('"', '', $str);

Wrap the double quotes inside single quotes.

Hope this helps you :)
