Count() - Retreive A Count Of A Column.
I'm performing a select statement against my database
SELECT *, COUNT(column)
FROM blah blah blah
WHERE blah blah blah
GROUP BY member
what i'm trrying to do is retreive a count of a column.
i.e.
$variable1 = $record->variable1;
$variable2 = $record->variable2;
$variable3 = $record->variable3;
$variable4 = $record->COUNT($variable3);
I keep getting the white screen of death, caused by the $variable4 line. How do I retrieve a count? the SQL is correct as I've ran it against the database itself in the sql window. but this has me beat.

New Record:Column Count Doesn't Match Value Count At Row 1
I get this error when I try to add a new record to my MySQL Database. "Column count doesn't match value count at row 1" So after searching through this forum it seems the problem is that the number of columns in my query doesnt match up to the number of columns in my table. Seems fairly easy to fix doesnt it. However my query has exactly the same number of columns as my table, they are also in the same order. Code:

Count & Max
I need to count the rows in a mysql table and to find the max value of a column. I am selecting count and max with mysql queries, but fail getting the results from my php code. For counting the rows I also tried mysql_fetch_array and then counting the rows in the array, but it didn't work either. Does someone know how to retreive the results of count() and max()?

How To Count Max In SQL?
Maybe this isn't the most apropriate place to ask mysql related question, but I think it is close enought to most php users and I always got find answers on this group. well, I need to count how meny rows have some maximum number. here is exact situation (striped down table) (pictID, jpeg name, #of votes) pict1, name1.jpg, 4 pict2, name2.jpg, 22 pict3, name3.jpg, 5 .... pict7, name7.jpg, 8 pict8, name8.jpg, 22 pict9, name9.jpg, 9 so, I need query (or set of querys) which will give me back rows 2 and 8 (I know, rows 1 and 7, but for easyer description, please let forget for moment that first is 0) I know what to do if I have only one picture with maximum votes: SELECT * FROM picts ORDER BY votes DESC LIMIT 1 (maybe not the best solution, but is working). now, I wanted to count how meny rows have MAX of votes, but I was unable to do that with my knowlage... SELECT max(votes)... and than $TotalMax=mysql_num_rows($result); in any combination (list), (while(list(too(much...) only failures... at the end I wanted to do SELECT with LIMIT so I can drow only those wining pictures: $query1 = "THAT one I don't KNOW"; $result1 = mysql_query ($query1) or die ("Query failed..."); list($new_limit) = mysql_num_rows($result1); //and now: $query2 = "SELECT * FROM picts ORDER BY votes DESC LIMIT $new_limit"; $result2 = mysql_query ($query2) or die ("Query failed..."); list($pict_data1,$pict_data2,$pict_data3) = mysql_fetch_array($result2); can anyone help me with that 1st query? or anyone have easyer solution? oh yes, I can not tell how meny pictures will have maximum number of votes. so far (in 4 years of manual handling of my site) there vere only 3 moments with 2 pictures sharing wining position, never more... normaly just one.

Seem To Count
I have just moved my site to a new server and my image upload script is failing due to an inability to count the file array. The upload form code allows a max of four images - the form code for an image looks like <input name="userfile[]" onchange="return TestFileType(this);" type="file" /> . When this form is posted the new script starts by finding how many image files have been uploaded $tot = count($userfile); . The problem is that $tot is always 0. count() does not seem to be able to count. I have checked that a file is being uploaded using $_FILES['userfile']['name'][0] and it is. This worked fine on the old server. I realise I could just loop though the filename array until I dont find one but I'd rather just leave the script unchanged. Any ideas where the problem lays?

Sum A Count
I am trying to find out how many repeat customers there are in a store. I want to print out a table that says something like 1 | 500 2 | 200 3 | 10 Meaning 500 customers ordered once, 200 twice, etc... If I run this query: Code: mysql_query("SELECT DISTINCT COUNT(*) as theCount FROM orders GROUP BY user_id ORDER BY theCount"); I get the numbers 1,2,3 for the different amount of times people ordered. If I don't use distinct I get 500 rows with 1, 200 rows with 2, etc. Once I grab 1, 2, and 3, I am not sure what to do with them to get the next numbers. I can't do WHERE COUNT(*)=5 so that is throwing me off.

Let's Count
I need a counter to repeat with a loop. After the loop is done, I need a certain amount of blank rows to be displayed for fillers (which doesn't sound good to have while (mysql (thing)) { $counter = 0; if (condition) { $counter++; /* All my re-occuring table info and variables go here-ish */ } if (6-$counter > 0) { /*Now I need code to repeat <tr><td> </td></tr> 6-counter times. How do I do that? */ } } I am basicly looking for counter to increase by 1 for each time the thing loops. Then when its done, and there are only 3 results produced that time around, I want 3 more empty rows to be produced for a total of 6. I need 6 rows, content or none. If more than 6 rows appear, then thats fine.

Multiple Count()
I was wondering what the most efficient way to perform multiple count queries is? Is there any tips you can give that will speed up the process? For instance, is is quicker to do count(*) or is it quicker to count a field that has the smallest amount of info? At the moment I am using a function to count 26 times, but it has slowed down the web page too much. What I need to count, is how many records there are for each letter of the alphabet.

Help With Mysql Count(*)
I've been tearing out my hair trying to get my latest project online. I have a user based site and some of the info is being stored in a mysql table where each record is identified by the user's username. I want to generate a list to be displayed online that shows the top ten users who have the most records. Basically just a list of the the most frequently occuring records in the table. Right now I am using the following SQL query: $sql = "SELECT user, COUNT(*) as number FROM tablename GROUP BY user ORDER by number desc LIMIT 10"; $result = @mysql_query($sql, $connection) or die("Couldn't Execute Query"); I'm getting data back but am not sure if it is correct or exactly how to display it on the page. I typically use: while ($row = mysql_fetch_array($result)) {} but am not sure how to extract the count for each record using this.

Count Down To Date.
I have been working for the past few months on an AOL instant messenger profile enhancement website, similar to sub profile. I am almost completely done working on a photo gallery which I've done with help from posts on this board and others. But i searched and searched and could find nothing specific to my question. How do I make a countdown script? So say I have a profile on my website, and I want to show a countdown to my birthday. I enter the date in the member's area to when i want to count down to, we'll say my birthday for example (august 4th) Then when someone views my profile, they see this: Bouley86's Birthday: XX Months and XX Days What kind of information would I have to collect and insert into my DB in order for this to work and what would I compare it to in order to get the numbers and how would I have to compare it.

Count Array?
I wrote a counter script which counts each unique visitor, and counts how often a visitor has visited. The data is stored in a "counter.txt" file divided by "||". The lines in the file are constructed as follows: linenumber||ip-address||times-visited|| e.g. .... 43||34.913.657.901||53|| 44||436.422.67.78||5|| 45||346.465.3.436||27|| .... I count unique visitors by counting the number of lines, but how can i count the total of hits? So that means adding up the 3rd part of each line... (I've searched php.net, and tried some of the array functions but i can't figure it out.)

Count Of Checkboxes (again)
I'm still stuck with this problem. Here's a quick recap/summary :- 1. Page 1:User checks 3 out of 10 checkboxes and submits form to page 2 2. Page 2:Item count shows 3 items. User checks an additional 2 checkboxes and presses Update button. Item count now shows 5 checkboxes are checked and "New" checkboxes remain checked. 3. Page 2:User is happy and submits form to page 3 4. Page 3:Form items are converted into printable text/data Pedro Graca very kindly offered a solution using "header('Location: <URL>')" which very nearly worked however my problem is that the form data needs to be posted to the page 3 when the user is done (if not for this then the solution was perfect). Using header() does not post the data and from what I have read elsewhere there is no way of making it do this. I can think of a really ugly solution by way of changing the form's action to page 3 the first time the Submit (to page 3) button is pressed and tell the user to press it again to get to page 3 but I don't like this much. By the way, I really would prefer to avoid JavaScript.

The following line prints something: echo $keywords[0][3]; However, when I then use the count function as follows: $count = count($keywords[0]); echo $count; The printed count is only 1. I know there are at least 4 items in the array as I proved above. The array was created with the preg_split function which I don't think matters. I don't know what I'm doing wrong. Seems simple.

Word Count
I was really shocked not to find this already submitted by someone in the PHP manual notes. <? function jnWordCount($text) { $results = array(); $pattern = '/[w0-9]+S+/' // matches wordy characters and numbers preg_match_all($pattern,trim($text),$results); return count($results[0]); } $sentence = ' Should be - (ready) ( 53 ) . , =-' echo jnWordCount($sentence); // outputs 4 // matches: array('Should','be','ready)',ཱ') ?> It counts the number of words ignoring non-wordy charcters and extra whitespace. Infintately better than: <? echo count(explode(' ',$sentence)); ?> Which really only counts the number of spaces not the number of words at all. The reason I'm posting this here is there is just one slight problem. I'm pretty new to regular expressions and they never seem to do exactly what I want. It doesn't seem to want to match single character words. <? echo jnWordCount('a 41 I 5'); // outputs 1. A match for ཥ' only ?>

Reset Count To Zero
On our Intranet, staff can fill in a form requesting permission to purchase items for their department. The online form is numbered like this: NZ - 06 - 183 ....where 06 represents the current financial year, and 186 represents the form number....which is incremented by 1 by selecting the last entry in the db and adding '1' to it. What they want now is for the counter to reset to 001 for the first form filled in at the beginning of the new financial year. By using the date() function and an 'if / else' statement I can determine the start of the new finacial year, but how will I reset the counter to 000....so that the first form filled in on April 1st will have the number 'NZ - 07 - 001'?
