How Do You Reset A Mysql Fetch Assoc
I'd like to do this list twice and I get noting the second time, I'm assuming I must reset the fetch? <?php do {?> <option value="<?php echo $row_RestDisplay['RID'];?>"><?php echo $row_RestDisplay['RestName'];?></option> <?php } while ($row_RestDisplay = mysql_fetch_assoc($RestDisplay)); If there is a function to reset the row to # 1 I can't find it in the Manual at php.

Weird Warning: Db2_fetch_array() [function.db2-fetch-array]: Fetch Failure
I've written a class Cars that is a holder class for <code>Car</code> and it's designed to fetch Car records from out DB2 database. And it works fine until I return the $result to the calling function. I can use my $result to print html table but only inside the getAll method. When the $result is returned to the calling function the $result source is no more working properly as expected by me though the resource id stays the same. Code:

Need To Fetch The Minimal Value Of The Items In The Array And Fetch The Key
function func_select_min_id($type_id_array){ foreach ($type_id_array as $type_id) $item_query = 'SELECT * FROM prefs'." WHERE id='".mysql_real_escape_string($type_id)."'"; $item_result = mysql_query($item_query) or die ("Error doing query for this item "); $item_row = mysql_fetch_array($item_result); $rewards[] = ($item_row['paid']*$item_row['paid2']); } } what this function does isnt that hard, I pass it an array of possible id's, which are basically mysql field id nr's and it looks up the concerning row, fetches 2 values and multiplies the 2, then the result is stuffed in a new array . My problem is I need to fetch the minimal value of the items in the array and fetch the key (so I need to re-establish which key actually corresponds to the product of the 2 values) .

Insert Into Table Via Assoc Array
I am trying to populate data from an array into a table, but i cant figure out what i am doing wrong. //mysql query $sql = "SELECT charge_location.dept_code, charge_location.week, Sum(charge_location.total_hrs_paid) AS sum_of_total_hrs_paid, Sum(charge_location.hrs_non_chargeable) AS sum_of_hrs_non_chargeable FROM charge_location GROUP BY charge_location.dept_code, charge_location.week"; $result = mysql_query($sql); $num_results = mysql_num_rows($result); //populate the stats_table for($i=0; $i<$num_results; $i++){ $row = mysql_fetch_array($result); mysql_query("insert into stats_summary values( ($row[dept_code]), ($row[week]), ($row[sum_of_total_hrs_paid]), ($row[sum_of_hrs_non_chargeable])) "); } PS i get no errors when it executes, just fails to populate the table.

Searching Multi Assoc Array
I have the following typical array: Array ( [0] => Array ( [Code] => product1 [Description] => Bla Bla [Price] => 7 ) [1] => Array ( [Code] => product2 [Description] => Bla Bla [Price] => 10 ) ) My question is, how can I search the "code" value, of this multidimension array, to check for an existing / same product, before entering the new row, (using array_push) so that I dont end up with duplicate products. I have tried in_array but i can not seem to get it to work. Code:

Fastest Way To Look For An Array Of Char?
If I have a string, (variable len), and I am looking for the first position of one char in array starting from position 'x' For example, // the 'haystack' $string = "PHP is great, php is ok"; // the needles $char[] = 'P' $char[] = 'r' $char[] = 'k' I would search the $string for the first $char starting from 3 and it would return 7, (for 'g'). I could use many strpos(...) but that does not sound very efficient. So what would be the fastest way to get the first position? And, I am using PHP 4.x, not 5, (otherwise I guess I would use strpos(...)).

Fastest Way To Do Database / Array Search
I am trying to write a script that allows users to search through a database of names. But rather than give a search string and then return all those that match, I would like it to search each time the user types a new letter in the text box. That's badly explained - this example might help! The user types "r" and I displays all the names with r in them. The user continues and types "i" so the textbox shows "ri" and displayed are all the results with "ri" in them. I as doing currently this by re-querying the SQL database where the names are hosted but it takes too long to query, return and refresh the page. What would be a better way of storing this database info to allow a faster search? Maybe load it into a PHP array first (stored in another file) and search within that? (Can you do 'clever' searches in PHP?) Or into a javascript array? The list could be upwards of 1000 names. The databse shouldn't change that often so I could have a script that updates the array every 24 hours or every time a new name is added.

Fetch Array
I have designed a debit-system database with a PHP frontend. The amounts need to be updated on a monthly basis. now i have 10 clients in the system. i can get all the fields and display them, but next to that, i need to insert a field where we can enter an amount per client and after all the new amounts have been filled in, i need to update the database with those amounts entered. I know that by using html forms to enter the info, i can submit the info and do a update statement but the problem is, is that i need to dynamically add the field to update the amount according to the amount of results resturned from the database.

MySQL Fetch A Number And Then Search Through That Array
Basically I have a very long array of integers. What I want to do is have MySQL fetch a number and then search through that array stoping at a number which is bigger than the number fetched then reporting the number it is bigger than and the number it is smaller than. PS: Also, would there be a way to do this for every value in an array. IE have an array of column names and then for every column name get the value and pan through the array. PSS: In addition after all that is done could it report the position in the array of the last value it was bigger than?

Fetch Array - Create A $_SESSION Variable
I am writing a contact management php page. In the page I use mysql_fetch_array() to show the search results. If the user searchs by first name, there are times when multiple entries come up. Once the data is displayed on the screen the user has the option to edit, or delete this entry in the database. So on this one screen it shows all the search results. If the user clicks on edit or delete, I then create a $_SESSION variable to bring this information to the edit or delete page. However this variable only gets created for the first entry when I do the mysql_fetch_array(). If I choose any entry after the first, it brings over the first entries information. How would I create a variable to bring this over to another page to edit or delete each specific contact. Is there a better way to do this?

Arrays: Howto Convert Assoc To Numeric
If I have a numeric array similar to the following: $tmpArray[0]="alpha"; $tmpArray[1]="beta"; $tmpArray[2]="charlie"; I can break it down like so list($first,$second,$third)=$tmpArray; This would mean $first="alpha", $second="beta" and $third="charlie" However, when I have an associate array like so $tmpArray["one"]="alpha"; $tmpArray["two"]="beta"; $tmpArray["three"]="charlie"; and do list($first,$second,$third)=$tmpArray; Then $first, $second, $third do not have values - Can someone give me an environmentally friendly workaround to make this work? I can think of explodes/implodes and a number of other methods, but I had believed I could reference the first element in an associate array with a zero... and the next with a numeric one, but that does not seem to be the case...

Serving Fastest Pages
I am in the process of starting a very large content website. We are looking at about 20,000 uniques per day. Now we only have 1 server (2GB/day transfer), so I am trying to keep the load down as much as possible. I have two options in our custom built CMS. I can have the pages be purely dynamic and call the content from the MySQL database on every page or I can build the new pages and the affected pages (if the article link is listed on another page) every night or whenever I feel. What this will do is build static .html pages (parse .html as php) with a minimal amount of php in them just for cookies, log-in stuff, etc. Do I have to worry about load with only 20,000 (~70,000 page views) per day or should I use the building static pages method? I want my site to be as fast as possible, obviously.

Mysql UPDATE - Is This The Fastest Way?
I have two tables. Table A gets the current stock level updated from Table B (table b is filled with the current stock level from distributor). Is this statement the fastest way to accomplish this? UPDATE products,products_temp SET products.products_quantity=products_temp.stock WHERE products.products_model=products_temp.sku; When I run this my OsCommerce site completely stops running until the update is finished. The products table has about 4,500 lines, and the products_temp table has about 6,400 lines. It takes about 3 minutes to update - so I am sure I have customers leaving. I am currently running this once per hour to keep my inventory levels current with my distributor.

Fastest Way To Format MySQL DATETIME In PHP 5

Its the speed that's key here, boys. We all know you can pull out and use a lame ass substring function. But we should all be above that by now.

Finding Fastest Times In Dataset
I have a table which contains race results for a swimming club. The table contains the following fields memberID - ID of swimmer meetID - ID of Meeting where race too place eventID - ID of individual race at the meet stroke - e.g. Freestyle, Breaststroke... distance - e.g. 50 (metres) time - swimmers time for the race in seconds. There is a record for each swimmer for each race they enter at each meet they attend. What I need to do is extract personal bests (PB's) from this dataset. This is only required for the last Meet entered. To get the PB I need to extract all the records for each event and for each member who raced at that meet calculate the difference between the time for the current event and the fastest previous event of the same stroke and distance. I have been doing it by running multiple queries in code loops. Can someone come up with a way of doing it in one query?

Fetch?
If I want to retrieve a single row. I would make a query and than use msql_fetch_row. (If I use this in a loop it will fetch the next row until it becomes false). If I want to retrieve multiple rows. I would make a query and than use msql_fetch_array etc.. Say I use a loop with msql_fetch_array and display the data in a table do I have to make a new query to display say the third row of the original table somewhere else on the page?

Ive got a problem, my server that im hosted on is a shared server and has a fire wall on the port i want to use for fetching images from another server that i rent. The only way i can do what i want to do is by ftp, I want to write a script on my web site server that fetches all the images from my other server via ftp. I have written a little script thats logs me in and browses the directorys, but im having problems fetching the images back to my web page server. Ive lookd into the ftp_fgets function but carnt seem toget around it. theres about 100+ images that change daily that i want to bring from the game server to my web page server. The ftp_fgets functions ect, gets them but as i can see puts them into a open file on my server. How can i do it for images? Anyone know of a tutorial or a ready made script i could use for fetchingthese images. Ive tryed a few from hotscripts and not had much luck, The game server that holds the images is hosted on windows and the web page server is hosted on linux, Like i said im nearly there, i have the files i want in a array i just need some way of getting them back to my page server. Slap wake up... By the way the game server is not http enabled, on way in is ftp .
