  • Super strange PHP error

    - by Industrial
    Hi everyone, When trying memcache:get, I'll get the following error message back: Message: Memcache::get() [memcache.get]: Server localhost (tcp 11211) failed with: Failed reading line from stream (0) I run a Windows 32bit test environment (XP) and here's how my code looks: function getMulti(array $keys) { $items = $this->memcache->get($keys); return $items; } My memcache servers are two local computers in the LAN that my dev. environment is connected to. Sure, I can turn the error logging off or just put an @ before the get function call, but that doesnt solve this issue. What can I do? Thanks a lot!

    - by user434885
    i have a web portal running which involves basic data entry. The issue being that this is highly sensitive data. And the credibility of the data entry personel is very low. Therefore i have implemented recording of IP when an entry is made. The Problem i am facing is if this if this person starts forwarding his IP from a proxy server then i am unable to track authenticity of the data. How do i detect if the IP forwarding is happening/ get the real ip address of the person.

  • MySql php: check if Row exists

    - by Jeff
    This is probably an easy thing to do but I'm an amateur and things just aren't working for me. I just want to check and see if a row exists where the $lectureName shows. If a row does exist with the $lectureName somewhere in it, I want the function to return "assigned" if not then it should return "available". Here's what I have. I'm fairly sure its a mess. Please help. function checkLectureStatus($lectureName) { $con = connectvar(); mysql_select_db("mydatabase", $con); $result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName'"); while($row = mysql_fetch_array($result)); { if (!$row[$lectureName] == $lectureName) { mysql_close($con); return "Available"; } else { mysql_close($con); return "Assigned"; } } When I do this everything return available, even when it should return assigned.

  • PHP array minor problem

    - by Sennheiser
    I'm really not sure how to explain this. It's so simple I can't fathom why it's not working. I have a loop. It puts a bunch of strings into an array. If I fill a single variable with any given string, it will output it perfectly. But filling an array with the strings will make it give me the dreaded: Array Array Array Array Array Array Array Array Note: my strings are not all 'Array'. The way I loop is: while(...) { $arr[] = $resultFromLoop; } Here is my var_dump. array(1) { ["tagName"]=> string(5) "magic" } array(1) { ["tagName"]=> string(4) "nunu" } array(1) { ["tagName"]=> string(5) "books" } array(1) { ["tagName"]=> string(0) "" } array(1) { ["tagName"]=> string(3) "zzz" } array(1) { ["tagName"]=> string(4) "grey" } array(1) { ["tagName"]=> string(3) "new" } array(1) { ["tagName"]=> string(6) "flight" }

  • [PHP] How to unset object's inherited properties ?

    - by vbklv
    I have an Object ( [id] => 1 [parent_id] => 0 [result:Database:private] => [db:Database:private] => mysqli Object ( [affected_rows] => 0 ... ) ) Obviously, the Object has inherited the 'db' and 'result' properties of the parent Database class. unset($object-result) nor unset($object-result:Database) nor unset($object-result:Database:private) work. How could I unset those properties when they are no longer needed (i.e. when the object properties are about to be output)? Is it a generally a good idea to have a database object as an inherited property of other classes (extend one Database class with all other classes that use database connections)?

  • PHP while loop, table row

    - by Elliott
    Hi, I'm trying to loop through a database and output data into a div, if there are 3 divs horizontally accross it will the start a new tr until it reaches another 3 etc. It is currently outputted like : [] [] [] [] [] [] Currently I have it working when it reaches 3 it starts a new row, but I don't know how I can only echo a new tr once? As it creates a new table row each time. echo '<table><tr>'; while ($result) { $i ++; if ($i&3) { echo '<td> <div>Row Data</div> </td>'; } else { echo '<tr> <td> <div>Row Data</div> </td></tr>'; } } echo '</tr></table>'; The $result variable is the recordset from my sql query, everything works fine I just don't know how to only create a new table row once? Thanks

  • help with php MVC problem

    - by aprencai
    hello, I have groups on my site and the urls have the following hierarchy: / groups / {id_group} / / groups / {id_group} / news / groups / {id_group} / gallery / groups / {id_group} / events / groups / {id_group} / events / {id_event} / groups / {id_group} / events / {id_event} / news / groups / {id_group} / events / {id_event} / gallery / groups / {id_group} / events / {id_event} / news As you can see a group can have news, gallery, etc. and in turn an event that is in a group can also have news, gallery, etc. How to implement this approach in a framework without specifying any specific one?, ie I would like some guidance on what would have modules, controllers, etc. Thanks.

  • PHP 1-liner each() with mysql_fetch_assoc()

    - by MVC You Know Me
    Hey All. Trying to create a 1-liner to loop through a mysql result set. Example: $sql = "SELECT uid, role FROM usr WHERE uid = '$this-uid'"; $r = db::q($sql); if($r-rows()) { $q = mysql_fetch_assoc($r-result); while(list($k, $v) = each($q)) { // would like to omit line above and consolidate here $_SESSION['usr'][$k] = $this->$k = $v; } } problem is that consolidating while loop like so: while(list($k, $v) = each(mysql_fetch_assoc($r-result)) returns an error a la each() not getting object or array, even though of course it is. I think the problem is a casting issue, but it does not seem you can do: each( (array) mysql_fetch_assoc($r-result)) Any ideas? I like to code as tersely as possible, and having "$q = mysql_fetch_assoc($r-result)" everywhere will annoy me, does already. Keep posted... Thanks!

  • PHP function: find argument's variable name, and function calls line number

    - by Majid
    I want to do something like this for simplifying logging operations. Any idea what I should put in for ?[1]? and ?[2]?? function log_var($var) { $line = ?[1]?; $var_name = ?[2]?; $line--; $filepath = 'log-' . date('Y-m-d'). '.txt'; $message = "$line, $var_name = $var\n"; $fp = fopen($filepath, "a"); fwrite($fp, $message); fclose($fp); @chmod($filepath, 0666); return TRUE; } This how I'd use the function in code (numbers are assumed to be line numbers in actual code): 23 $a = 'hello'; 24 log_var($a); 25 $b = 'bye'; 26 log_var($b); And this is what I want to be written to the log file: 23, a = hello 25, b = bye

    This works: $customerBox = mysql_query("MY SQL STATEMENT HERE"); $boxRow = mysql_fetch_array($customerBox); $customerBox = mysql_query("MY SQL STATEMENT AGAIN"); while($item = mysql_fetch_assoc($customerBox)) { foreach ($item as $columnName = $value) { if (empty($value)) { print $columnName; } } } This does not: $customerBox = mysql_query("MY SQL STATEMENT HERE"); $boxRow = mysql_fetch_array($customerBox); while($item = mysql_fetch_assoc($customerBox)) { foreach ($item as $columnName = $value) { if (empty($value)) { print $columnName; } } } Why? I guess I don't understand how variables work yet.
