PHP - Adding Values Of Array Together
hello, how would i add the values off all results in the $pamount array?
Code: [Select] $result2 = mysql_query("SELECT * FROM pobook WHERE jobnumber = '$jobid'"); while($row2 = mysql_fetch_array($result2)) { $pamount=$row2['amount']; echo "<tr>"; echo "<td>" . $pamount . "</td>"; echo "</tr>"; echo "<tr>"; echo "<td>VALUE OF ALL RETURNED $pamount HERE</td>"; echo "</tr>"; Similar TutorialsI have the following multidimensional array where each sub-array represents quantity[0] and item #[1]: Array ( => Array ( => 1 [1] => 12113 ) [1] => Array ( => 2 [1] => 21200 ) [2] => Array ( => 4 [1] => 10200 ) [3] => Array ( => 1 [1] => yyyy ) [4] => Array ( => 20 [1] => xxxxx ) [5] => Array ( => 5 [1] => 21200 ) I'm trying to consolidate like items. For example I need to create a new array that reflects any duplicate part numbers with a combined quantity. (ie. ... => 7 [1] => 21200 ... Hey guys: If I some multi-dimensional arrays, like so: Code: [Select] array { array { [0]=> "Path1" [1]=> "10" } } array { array { [0]=> "Path2" [1]=> "16" } array { [0]=> "Path3" [1]=> "110" } } How can I add all of the values of key 1? I know its a foreach loop, but I can't figure it out... would it be this? Hi I am gathering numbers in an array and then want to add together all the numbers attached to the same email so I end up with the Grand totals of each email address. Below is the code I am using to pull out the email and attached values Code: [Select] $getcashdonationsdb = $wpdb->get_results("SELECT * FROM cashdepo WHERE cause='$causename' AND status='2' ORDER BY user DESC"); $i = 0; while($i < $count2) { foreach($getcashdonationsdb as $getcashdonationsdb){ $dataa[$i]['email'] = $getcashdonationsdb->email; $dataa[$i]['cost'] = $getcashdonationsdb->cost; } } Anyone have any suggestions how I can achieve this most efficiently. Hi all, I'm a first time poster here and I would really appreciate some guidance with my latest php challenge! I've spent the entire day googling and reading and to be honest I think I'm really over my head and need the assistance of someone experienced to advise the best way to go! I have a multi dimensional array that looks like (see below); the array is created by CodeIgniter's database library (the rows returned from a select query) but I think this is a generic PHP question as opposed to having anything to do with CI because it related to working with arrays. I'm wondering how I might go about searching the array below for the key problem_id and a value equal to a variable which I would provide. Then, when it finds an array with a the matching key and variable, it outputs the other values in that part of the array too. For example, using the sample data below. How would you recommend that I search the array for all the arrays that have the key problem_id and the value 3 and then have it output the value of the key problem_update_date and the value of the key problem_update_text. Then keep searching to find the next occurrence? Thanks in advance, as above, I've been searching really hard for the answer and believe i'm over my head! Output of print_r($updates); CI_DB_mysql_result Object ( [conn_id] => Resource id #30 [result_id] => Resource id #35 [result_array] => Array ( ) [result_object] => Array ( ) [current_row] => 0 [num_rows] => 5 [row_data] => ) Output of print_r($updates->result_array()); Array ( [0] => Array ( [problem_update_id] => 1 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Some details about a paricular issue [problem_update_active] => 1 ) [1] => Array ( [problem_update_id] => 4 [problem_id] => 3 [problem_update_date] => 2010-10-01 [problem_update_text] => Another update about the problem with an ID of 3 [problem_update_active] => 1 ) [2] => Array ( [problem_update_id] => 5 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of four [problem_update_active] => 1 ) [3] => Array ( [problem_update_id] => 6 [problem_id] => 4 [problem_update_date] => 2010-10-12 [problem_update_text] => An update about the problem with an ID of 6 [problem_update_active] => 1 ) [4] => Array ( [problem_update_id] => 7 [problem_id] => 3 [problem_update_date] => 2010-10-12 [problem_update_text] => Some new update about the problem with the ID of 3 [problem_update_active] => 1 ) ) Using curl_multi, I have loaded up 3 url's and then printed the array. 1) How can I also set a timestamp on output to let me know when each url was run? 2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"? Code <?php function multiRequest($data, $options = array()) { // array of curl handles $curly = array(); // data to be returned $result = array(); // multi handle $mh = curl_multi_init(); // loop through $data and create curl handles // then add them to the multi-handle foreach ($data as $id => $d) { $curly[$id] = curl_init(); $url = (is_array($d) && !empty($d['url'])) ? $d['url'] : $d; curl_setopt($curly[$id], CURLOPT_URL, $url); curl_setopt($curly[$id], CURLOPT_HEADER, 0); curl_setopt($curly[$id], CURLOPT_RETURNTRANSFER, 1); // post? if (is_array($d)) { if (!empty($d['post'])) { curl_setopt($curly[$id], CURLOPT_POST, 1); curl_setopt($curly[$id], CURLOPT_POSTFIELDS, $d['post']); } } // extra options? if (!empty($options)) { curl_setopt_array($curly[$id], $options); } curl_multi_add_handle($mh, $curly[$id]); } // execute the handles $running = null; do { curl_multi_exec($mh, $running); } while($running > 0); // get content and remove handles foreach($curly as $id => $c) { $result[$id] = curl_multi_getcontent($c); curl_multi_remove_handle($mh, $c); } // all done curl_multi_close($mh); return $result; } $data = array(array(),array()); $data[0]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Pearl+Jam&output=json'; $data[1]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Black+Eyed+Peas&output=json'; $data[2]['url'] = 'http://search.yahooapis.com/VideoSearchService/V1/videoSearch?appid=YahooDemo&query=Nirvana&output=json'; $r = multiRequest($data); print_r($r); ?> Output Array ( => Pearl Jam [1] => Black Eyed Peas [2] => Nirvana ) Preferred Output 01:00:01 Pearl Jam 01:00:02 Black Eyed Peas 01:00:03 Nirvana Hey! How've you been? This should be simple but I can't make it work. I have a few database values from a user entry. The page queries the database and I can print them no problem. I want to add them and display the total of these values. I've tried about two dozen ways of doing and I just can't get them to add. Where I have "fee_total" I want it to be the sum of the values "fee+upgrade7+tax". This is the snippet of what I'm working on. I won't attach any of what I have tried because, well, there are too many attempts and nothing worked $sql = ("SELECT * FROM Teamregister WHERE pkSoloregisterID=$pkSoloregisterID"); $query = mysql_query($sql); $result = mysql_query($sql); $myrow = mysql_fetch_array($result); printf ('<form action="https://www.mysite.com/cgi-bin/webscr" method="post"> <p>Your registration fee is <strong>$%s</strong>.</p>', $myrow['total_fee']); echo ("<input type='hidden' name='item_name_1' value='Registration Fee'>"); printf ('<input type="hidden" name="amount_1" value="%s">', $myrow['total_fee']); echo ("<br /><div align='center'> <input type='submit'' value='Pay Online'> </form>'); Make sense? Like I said, the values are already there but the math isn't happening. To check I tried using individual DB values instead of "total_fee" and the numbers show up. Just cannot get them to add. Hi, I currently have a string with some values in it: $a_random_string="some random text, goes here - $123<br>some more random text goes here - $53 (text 123 )<br>ANother line of text - $126"; Now I want to add all the values that have a '$' before the value eg; $123. So in this case I would end up with: 302 How would I do this? Thanks, mme Code: [Select] $product_id=$_GET['product']; $sql500="SELECT * FROM $tbl_name3 WHERE product_id='$product_id'"; $result500=mysql_query($sql500); $num_rows500=mysql_num_rows($result500); while($row500=mysql_fetch_array($result500)){ extract($row500); $review_product_rating_total=$review_product_rating; //What do I do here? } $average_rating=$review_product_rating_total/$num_rows500; I need a way to take a column of product ratings (0-5 in 1/2 increments), add them together, and divide by the number of rows taken from the database. I know how to get the number of rows with mysql_num_rows. But how would I add together the data from database? I have a store number that i want to add and echo. This resembles an invoice so i my table has unit_price and total_value which is defined by by multiplying unit_price and pieces. Now that i want to print invoice i want to know how to add all items that are from that invoice_id Code: [Select] //get the total value for order $sql_value = "SELECT total_value FROM `".TABLE_ORDERDETAILS."`WHERE order_id = $record_order[order_id]"; $rows_value = $db->fetch_all_array($sql_value); foreach($rows_value as $record_value){ $value = $record_value[total_value]; } Hi, I have a database with some rows. in each row there is a number such as: 0.0023 or 0.0135... I have the following code to loop though them and add the numbers up but it always returns 0? Code: [Select] $sql="SELECT * FROM tickets WHERE `round` = '$round' AND `confirmed` = 'yes' ORDER BY id ASC"; $result=mysql_query($sql); $row=mysql_fetch_array($result); while($row = mysql_fetch_array( $result )) { $balance = $balance + $row['amount']; } Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. I have mysql select query shown below retrieving data from a database:
$sql = "
SELECT
student, sum( test_score ) as score
FROM
test
INNER JOIN
level
ON
test.level_id = level.level_id
GROUP BY
student"
$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
while ($row = $result->fetch_array(MYSQLI_ASSOC))
{
var_dump($row);
}
}
On inspection of the retrieved array with var_dump(), i have these result below:
array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. Hi here is my problem, i have a link like : index.php?id=1 When user click on it, a cookie array is set with a value of 1 when user clicks on another link with an id of 2, the same cookie is set with another value of 2, at the end , the cookie should read: Code: [Select] array( [0] => 1 [1] => 2 ) Can someone please explain how to do this? im struggling :S Hi all, I'm pretty much a noob, and I've tried looking in the manual, but I don't know enough to even look in the right direction. Implode function perhaps? I'm pulling values from a MySQL database... for example: $food $drink $price If the array has a value in it , I want it to report the value and then add a separator (like a comma) between the values. If the array is empty, I don't want the orphaned comma. For example: $food = "" $drink = "beer" $price = "five dollars" Right I can print: beer five dollars even: , beer, five dollars But what I want is: beer, five dollars Thanks. ~Wayne Hello, I am trying to add all rows in the same column together. So here is the basic scheme: id l column1 1 l 1 2 l 2 3 l 3 Second table id l variable1 1 l 3 2 l 5 3 l 6 I basically want to add 5+3+6 and set it to a variable named '$total'. Would this be done using while loops? Here is the code I have been messing with. $sql="SELECT column1 from table1 where id='$userid'"; // userid would be set near the top of the page $sql2=mysql_query($sql,$conn); while($rows=mysql_fetch_array($sql2)){ $getid = $rows['column1']; $sql3="SELECT variable1 FROM table2 where id='$getid'"; $sql4=mysql_query($sql3,$conn); while($items=mysql_fetch_array($sql4)){ // Then I'm getting lost... } } Can you at least see what I am trying to do? I'm not even sure if this is the right approach, any help would be appreciated! I am trying to get info from a table, add rows in that table, and put the added value back into the table in another field...I want to add field1 and field2 of every row and put the total in the total row. Heres what the echo gives me Susan 14 Mary 18 Bob 13 Sam 21 heres the database mysql> SELECT total_val FROM table; +-----------+ | total_val | +-----------+ | 21 | | 21 | | 21 | | 21 | +-----------+ heres the code.... <?php require("connection.php"); mysql_select_db("database", $connection); echo "<br />"; $result = mysql_query("SELECT * FROM table"); while($row = mysql_fetch_array($result)) { $values = ($row['field1'] + $row['field2']); $sql=mysql_query("UPDATE table SET total = '$values'"); echo $row['user_name'] .

Hi, I would like to know if there's a way to quickly collect and sort form data, then use that data in an if statement. I've tried for a while now and i just can't seem to figure it out. I would like to do this with radio buttons. Hopefully this will make it clear: Code: Code: [Select] <?php if (isset($_POST['submit'])) { // I don't know how to do this but maybe something like // if $_POST values == "Yes" // put them into an array // then count how many are in the array, e.g. 2 if 2 "Yes" radio buttons are selected $count = count($array) . " Yes values selected"; echo $count; //else if do the same for "No" values // hopefully this is understandable } ?> <!-- i want to take these values and group them, so all the "Yes" values selected together and the "no" values together --> <form method="post" action=""> <input type="radio" name="first" value="Yes" /> <input type="radio" name="first" value="No" /> <input type="radio" name="second" value="Yes" /> <input type="radio" name="second" value="No" /> <input type="submit" name="submit"> </form> |
