mysql - PHP PDO Security -


I am trying to work with PDO for the first time and I want to know what I am doing, how safe is it I

, I'm also new to PHP.

I have a question that when a user passes my page, the page takes a variable using GET and then runs.

With PHP, I've always used mysql_real_escape to get my varietates sanitized.

Can anyone see security flaws with this?

// Get the person ID $ User ID = $ _GET ['userID']; // People $$ sql = "Select * Individuals with ID = $ userID"; $ Q = $ conn- & gt; Query ($ sql) or die ($ conn- & gt; error ()); While ($ r = $ q- & gt; Fetch (PDO :: FETCH_LAZY)) {echo '

Do not use the query, prepare:

$ userID = $ _GET ['userID']; $ Sql ​​= "People from WHOE ID =: userid"; $ Q = $ conn- & gt; Ready ($ sql) $ q- & gt; Execute (Arrays (': userid' = & gt; $ userID)); While ($ r = $ q- & gt; Fetch (PDO :: FETCH_ASSOC)) {echo '& lt; Div class = "mis-per" & gt; '; Echo '& lt; Span class = "date-submitted" & gt; . $ R ['date_submitted'] '& lt; / Span & gt; '; // more STUF echo & lt; / Div & gt; '; }

The SQL statement can include the zero or more named (: name) or question mark (?) Parameter markers, for which the actual value is replaced when the statement is executed .

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
