Should an ampersand be URL encoded in a query string?
(2 answers)
Closed 2 years ago.
I have with an unwanted replaced, and not able to figure out how to fix it.
When you echo the following string in PHP
echo('?hash=123&rid=111×tamp=123');
The output is:
?hash=123&rid=111×tamp=123
Note that ×tamp has been replaced with ×tamp
I tried to escape it by using \×tamp but that doens't work.
How can I prevent PHP replacing this?
You can reproduce this error online using http://phptester.net/
You have to escape that string, because & is a special symbol in HTML.
echo htmlspecialchars('?hash=123&rid=111×tamp=123');
More information on the PHP site: https://www.php.net/manual/en/function.htmlspecialchars.php

How to use str_replace to replace single and double quotes

Closed 4 years ago.
I'm having trouble replacing a single quote in a string, the purpose is to create part of an URL
For example : If I type in "Villeneuve d'ascq" I would want to have :
Villeneuve+d%27ascq", %27 being the ascii equivalent of (')
I tried using str_replace("'", ord("'"), string_name) but it doesn't seem to work
Any help would be appreciated and feel free to ask for any more details
Please try this :
echo 'test';

I have a string in PHP code like this:
$string = "This is a PHP code";

If I understood your question properly, you want character at 3rd index then write following line ;)
echo $string[3];

json_encode() escaping forward slashes

When i insert url like this
alliedpaint-001-site1.smarterasp.net/white.png
in mysql and encode it using json my url shows like this
alliedpaint-001-site1.smarterasp.net\/white.png
How i can solve this?
json_encode returns the string, it inserts "\" in order to avoid special interpretation.
you can do 2 things-
1) json_encode($mystring, JSON_UNESCAPED_SLASHES);
or
replace "\" with space using regex.
Hope this helps.

How can I prevent SQL injection in PHP?
(27 answers)
Closed 8 years ago.
I have a string which is a path and is a variable in which I have to save in my database. But the path is
C:\foldera\folderb\folder1\folder2
and obviously I need it to be
C:\\foldera\\folderb\\folder1\\folder2
for the insertion in database of mysql.
Please help me find the solution. I tried str_replace but it won't work.
Thanks in advance.
The function you are looking for is addslashes($string); This function adds the slashes to turn your string into the string you are looking for. But if you are planning on using it as a parameter in an SQL statment you want to use mysqli_real_escape_string()
Also use single quotes in the string in order for addslashes() to work properly. double quotes will parse it as \f not just '\'.

Use htmlspecialchars before printing:
$text = htmlspecialchars($text)
You can escape ampersands & as well as quotes and brackets using the htmlspecialchars() function.
Like the others said, htmlspecialchars() works. Also check out htmlentities() which has a broader range of characters to replace for further scrubbing of the string.
