mysql-real-escape-string

问题 i am trying escape some data before it goes into my database, but i keep getting this error: Warning: mysql_real_escape_string(): Access denied for user Now this would usually suggest that i have not connected to the database (it also states (using password: NO)). I was a little confused by this because when connecting to a database i have a 'die' clause so if it fails to connect i get told about it. So i tested this theory by running a simple query in the same function that im trying to

问题 I just moved to a new hosting company and now whenever a string gets escaped using: mysql_real_escape_string($str); the slashes remain in the database. This is the first time I've ever seen this happen so none of my scripts use stripslashes() anymore. This is on a CentOS 4.5 64bit running php 5.2.6 as fastcgi on a lighttpd 1.4 server. I've ensured that all magic_quotes options are off and the mysql client api is 5.0.51a. I have the same issue on all 6 of my webservers. Any help would be

问题 So in this program I'm writing, I actually grab a SQL query from the user using a form. I then go on to run that query on my database. I know not to "trust" user input, so I want to do sanitization on the input. I'm trying to use mysql_real_escape_string but have been unsuccessful in getting it to work. Here's what I'm trying, given the input: select * from Actor; //"query" is the input string: $clean_string = mysql_real_escape_string($query, $db_connection); $rs = mysql_query($clean_string,

问题 I'm having issues escaping/stripping strings with PHP/MySQL - there always seems to be redundant slashes. Let's take the following string as an example: <span style="text-decoration:underline;">underline</span> When adding a string to the database, I'm escaping it with mysql_real_escape_string() and the following gets stored in the database ( EDIT : checked this by querying the database directly with mysql app): <span style=\\\"text-decoration:underline;\\\">underline</span> When reading back

问题 So this is something we all should know about, and played on my mind when I first seen it.. I know that mysql_escape_string is deprecated from 5.3 but what was the actual difference in mysql_real_escape_string . What I thought was that mysql_real_escape_string is the exact same as mysql_escape_string apart from mysql_real_escape_string takes a second argument for the mysql resource. so then I thought well surly there must be some difference as to how strings are handled because there would

问题 I have seen a few people on here state that concatenating queries using mysql_real_escape_string will not protect you (entirely) from SQL injection attacks. However, I am yet to see an example of input that illustrates an attack that mysql_real_escape_string would not protect you from. The majority of examples forget that mysql_query is limited to one query and use mysql_real_escape_string incorrectly. The only example I can think of is the following: mysql_query('DELETE FROM users WHERE user
