• PHP CSV, how to get previous and next 3 rows from current row

  - by Kalpesh Mehta

  I am currently using fgetcsv in php to get rows in CSV file. For each row, I need it's 3 previous rows and 3 next rows for some requirement. while(($data = fgetcsv($handle, 5000, ",")) !== FALSE) { //$data is current row data //I need previous rows and next rows data } I don't know how to try this, as each while iterate will be having the current row's information. Is there anything we can achieve this within the fgetcsv loop? I am also open for other alternatives for this problem.

• Formatting PHP Code within Vim

  - by gacrux

  I'm currently using Vim as a lightweight IDE. I have NERDTree, bufexplorer, supertab, and ctags plugins which do almost everything I want. Only big thing missing for me is auto code formatting. I'm working with some messy PHP code which has inconsistent indenting and code formatting, ideally I could highlight the code I want formatted (whole files would be fine too) and run a command to tidy it. Does anybody have a nice solution for this working in Vim?

  Hi guys, I need to save files with non-latin filenames on a filesytem, using PHP. I want to make this work cross-platform. How do I know what encoding I can use to write the file?

• PHP, MySQL - My own version of SALT (I call salty) - Login Issue

  - by Fabio Anselmo

  Ok I wrote my own version of SALT I call it salty lol don't make fun of me.. Anyway the registration part of my script as follows is working 100% correctly. //generate SALTY my own version of SALT and I likes me salt.. lol function rand_string( $length ) { $chars = "ABCDEFGHIJKLMNOPQRSTUWXYZabcdefghijklmnopqrstuwxyz1234567890"; $size = strlen( $chars ); for( $i = 0; $i < $length; $i++ ) { $str .= $chars[ rand( 0, $size - 1 ) ]; } return $str; } $salty = rand_string( 256 ); //generate my extra salty pw $password = crypt('password'); $hash = $password . $salty; $newpass = $hash; //insert the data in the database include ('../../scripts/dbconnect.php'); //Update db record with my salty pw ;) // TESTED WITH AND WITHOUT SALTY //HENCE $password and $newpass mysql_query("UPDATE `Register` SET `Password` = '$password' WHERE `emailinput` = '$email'"); mysql_close($connect); However my LOGIN script is failing. I have it setup to TEST and echo if its login or not. It always returns FAILED. I entered the DB and changed the crypted salty pw to "TEST" and I got a SUCCESS. So my problem is somewhere in this LOGIN script I assume. Now I am not sure how to implement my $Salty in this. But also be advised that even without SALTY (just using crypt to store my pass) - I was still unable to perform a login successfully. And if you're gonna suggest i use blowfish - note that my webhost doesn't have it supported and i don't know how to install it. here's my login script: if (isset($_POST['formsubmitted'])) { include ('../../scripts/dbconnect.php'); $username = mysql_real_escape_string($_POST['username']); $password = crypt(mysql_real_escape_string($_POST['password'])); $qry = "SELECT ID FROM Register WHERE emailinput='$username' AND Password='$password'"; $result = mysql_query($qry); if(mysql_num_rows($result) > 0) { echo 'SUCCESS'; //START SESSION } else { echo 'FAILED'; //YOU ARE NOT LOGGED IN } } So what's wrong with this login? Why isn't it working just using the crypt/storing only crypt? How can i make it work storing both the crypt and randomly generated SALTY :) ? Ty advance
