PHP - Php Is Eating My Little Green Buddha - Foreach Loop Help Needed
Okay, I'm going nuts here. I have a (nested) array of search terms that I'm working with. When I run a foreach loop on it, things go bad. Here's a test loop I ran:
Code: [Select] echo $pqPhrases[0]["terms"]." - ".$pqPhrases[1]["terms"]." - ".$pqPhrases[2]["terms"]."<br>"; foreach($pqPhrases as $pqPhrase) { echo $pqPhrases[0]["terms"]." - ".$pqPhrases[1]["terms"]." - ".$pqPhrases[2]["terms"]."<br>"; } Output (emphasis added): doberman - camaro - little green buddha with pink nose doberman - camaro - doberman doberman - camaro - camaro doberman - camaro - camaro If I switch to a "for" loop, the results are as expected: Code: [Select] echo $pqPhrases[0]["terms"]." - ".$pqPhrases[1]["terms"]." - ".$pqPhrases[2]["terms"]."<br>"; for($x=0;$x<count($pqPhrases);++$x) { echo $pqPhrases[0]["terms"]." - ".$pqPhrases[1]["terms"]." - ".$pqPhrases[2]["terms"]."<br>"; } Output: doberman - camaro - little green buddha with pink nose doberman - camaro - little green buddha with pink nose doberman - camaro - little green buddha with pink nose doberman - camaro - little green buddha with pink nose The other thing I tried was to redefine a simplified array, which also gives results that are expected: Code: [Select] $pqPhrases=array(); $pqPhrases[0]["terms"]="camaro"; $pqPhrases[1]["terms"]="doberman"; $pqPhrases[2]["terms"]="little green buddha with pink nose"; echo $pqPhrases[0]["terms"]." - ".$pqPhrases[1]["terms"]." - ".$pqPhrases[2]["terms"]."<br>"; foreach($pqPhrases as $pqPhrase) { echo $pqPhrases[0]["terms"]." - ".$pqPhrases[1]["terms"]." - ".$pqPhrases[2]["terms"]."<br>"; } Output: doberman - camaro - little green buddha with pink nose doberman - camaro - little green buddha with pink nose doberman - camaro - little green buddha with pink nose doberman - camaro - little green buddha with pink nose I'm thoroughly flumoxed. I can't figure out why the first example doesn't work. Am I missing something obvious here? Can anyone help? Similar TutorialsBelow is my output on the browser: Student: Kevin Smith (u0867587) Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade Year: 3 Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B Session: AAB Session Mark: 72 Session Weight Contribution 20% Session: AAE Session Mark: 67 Session Weight Contribution 40% Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B Session: AAD Session Mark: 61 Session Weight Contribution 50% Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this. Below is the code: Code: [Select] $sessionMark = 0; $sessionWeight = 0; $courseMark = 0; $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)) { $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']); $sessionWeight += ($row['SessionWeight']); $courseMark = ($sessionMark / $sessionWeight * 100); if($studentId != $row['StudentUsername']) { //Student has changed $studentId = $row['StudentUsername']; $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n"; } if($courseId != $row['CourseId']) { //Course has changed $courseId = $row['CourseId']; $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n"; } if($moduleId != $row['ModuleId']) { //Module has changed if(isset($sessionsAry)) //Don't run function for first record { //Get output for last module and sessions $output .= outputModule($moduleId, $moduleName, $sessionsAry); } //Reset sessions data array and Set values for new module $sessionsAry = array(); $moduleId = $row['ModuleId']; $moduleName = $row['ModuleName']; } //Add session data to array for current module $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']); } //Get output for last module $output .= outputModule($moduleId, $moduleName, $sessionsAry); //Display the output echo $output; I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72? Hey guys, Got another question im hoping someone can help me with. I have a foreach loop (for use in a mysql query): foreach ($interests as $interest) { $query .= "($id, $interest), "; } problem is i do not want the comma(,) in the last loop. Is there some kinda of function i can use so it does not insert it on last loop? Or should i just use a for loop with a nested if loop? something like ; for($i=0; $i < count($interests); $i++){ $query .= "($id, '$interests[$i]')"; if($i + 1 < count($interests)) { $query .= ", "; } } Cheers guys Hey guys, need help on some addition. foreach($login as $line_num => $line) { $login = explode(" ", htmlspecialchars(str_replace(" "," ",$line))); if(stristr($login[1], "\n")) $login[1] = substr($login[1], 0, strlen($login[1])-2); $account_data[$line_num] = array($login[0], $login[1]); $UserID = $login[0]; $AuthKey = $login[1]; $MobLink = "http://mobsters-fb-apache-dynamic-lb.playdom.com/mob_fb/"; $RefreshStat = file_get_contents($MobLink."refresh_stat_manual?user_id=".$UserID."&auth_key=".$AuthKey); $Cash = explode ("<cash>", $RefreshStat); $Cash = explode ("<", $Cash[1]); $Cash = $Cash[0]; $CashForEcho = "$".number_format($Cash[0]); echo $CashForEcho."<br/>"; echo "<br/><br/>"; } The variable $Cash will be dynamic for each user I put in the $login_file, and I need to add all of those values up. So say I put in 3 users within the $login_file, and the $Cash for user 1 was $3,000, the $cash for user 2 was $6,000 and the $cash for user 3 was $1,000, I want to be able to automatically add them all up, so it would echo '$10,000' at the end. Hope I've explained it for you guys to understand easily enough, if not let me know. Thanks I have a foreach loop which shows the breadcrumb display. But it's stopped working.

Many thanks, James. hello why does my div move when i use a foreach loop ? if i use the code below i get the following i added a border style to the div so i can see that some are in and some are out: result 1 = not in a div result 2 = in a div result 3 = in a div etc then on the end i get a div with no result in it Code: [Select] function name(){ echo' <div id="divName">'; $a = Class::find_all(); foreach ($a as $ab){ $name = $ab->name; $dest = $ab->destination; <ul> <li><a href="index.php?pageID='.$dest.'">'.$name.'</a></li> </ul>'; } echo'</div>'; } thanks rick Hello. I was wondering if anyone could please help with a problem I seem to be having a problem with my foreach loops. I have an array that holds other arrays. When I am trying to populate the database tables with the information in each array, things are going horribly wrong. This is my code: $tabledata = $this->db->get('tableinfo'); $i = 0; $_temp = array(); foreach($tabledata->result() as $row) { $data[$i] = $this->callAPI("lateststandings&records=3&category=" . $row->category . "&distance=" . $row->distance_id); array_push($_temp, $row->dbname); $i++; } $j = 0; foreach($data[$j]['Records']['Record'] as $record) { $record['FirstName'] .= " " . $record['LastName']; $this->db->replace($_temp[$j], $record); $j++; }
When this is run 2 things are happening:
1) What I am expecting to happen is, there should be 3 rows added to each table. But only 1 is being added to each table. I am not sure what I am doing wrong in these loops.
Hello to all I have problem a with my foreach loop.. First : Is it possible to rename each element that's been outputted everytime the loop execute? Code: [Select] <?php $arr = array(mikel, 17, cambodia, 50kgs, 5 feet, anna, 21, peru, 45kgs, 6 feet); foreach ($arr as &$value) { $value = $value; } ?> What i would like on the result of the foreach loop is name : mikel Age : 17 address : cambodia weight : 50kgs height : 5 feet is this possible? Second : i want to echo the result of the for each loop in every 5 turns. result 1 = mikel, 17, cambodia, 50kgs, 5 feet result 2 = anna, 21, peru, 45kgs, 6 feet Can anyone help me on this? thanks Object- Take array of IP addresses and add up all occurrences of a particular IP address. //$item is an array of IP addresses foreach ($item as $key => $unique_ip) { if($unique_ip == $ip) $a++; } echo $a; I get a blank page. What am I missing? foreach ($export as $group => $arrayOpts) { //echo $arrayOpts[0]["choice"]; This returns No /** * If the option hasn't been selected, leave that part out entirely **/ if (!empty($arrayOpts)) // if the entire options array isn't empty, we'll display { if ($arrayOpts[0]["choice"]!="0" || $arrayOpts[0]["choice"]!="No") { $pdf->Cell(40,10,$group,0,1); $pdf->ImprovedTable($header,$arrayOpts); $pdf->Ln(); } } } Unfortunately I can't show print_r's at the moment, the main issue is it's running those $pdf-> lines even if that variable is equal to No, I proved it because up above commented out returns No, but it still runs the pdf code. Any thoughts? Been staring at it a while, maybe it's something in my conditional statement? Thanks. Hello all,
I have the following code (which obviously has unnecessary redundancy) and I would like to replace it with a ForEach loop in order to make the code shorter, and perhaps more efficient.
// validate input $valid = true; if (empty($store_name)) { $storeNameError = 'Please enter a Store Name'; $valid = false; } if (empty($item_description)) { $itemDdescriptionError = 'Please enter an Item Description'; $valid = false; } if (empty($qty_pkg)) { $qtyPkgError = 'Please enter Quantity or Package'; $valid = false; } if (empty($pkg_of)) { $pkgOfError = 'Please enter the Count/Quantity'; $valid = false; }At this point (being a newbie) I'm trying to wrap my head around the ForEach statement, but all I can achieve is to tie-my-knickers-in-a-knot. I know this is childs-play for some of you here, and I hope you can help me get a working ForEach statement. The following is the declaration of some related arrays (which potentially may be incorrect/inefficient as well): // Create an array of the fields we want to capture, along with their labels $fields = array( 'store_name'=>'Store Name', 'item_description'=>'Item Description', 'qty_pkg'=>'Qty / Pkg', 'pkg_of'=>'Pkg. Of', 'price'=>'Price', 'flyer_page'=>'Flyer Page #', 'limited_time_sale'=>'Limited Time Sale Days', 'nos_to_purchase'=>'Nos. to Purchase' ); // Create an array-type variable to keep track of validation errors $fieldsErrorMsgs = array( 'storeNameError'=>'Please enter a Store Name', 'itemDescriptionError'=>'Please enter an Item Description', 'qtyPkgError'=>'Please enter Qty or Pkg', 'pkgOfError'=>'Please enter the Qty', 'priceError'=>'Please enter the Price', 'flyerPageError'=>'Please enter the Flyer Page #', 'limitedTimeSaleError'=>'Please enter the Limited Time Sale Days', 'nosToPurchaseError'=>'Please enter the No(s). to Purchase' );And here's what I've tried...but there seems to be the following two problems with the ForEach portion of the code: 1) No errors are being displayed (inspite of the fact that I'm leaving all fields blank and clicking on the [Create] button 2) A row is being created (with all blank columns) $valid = true; $errors = array(); foreach($fields AS $field=>$label){ //The following line is using the ternary operator, it's basically a shorthand if/else assignment. $errors[$field] = (!isset($values['store_name']) || !strlen($values['store_name'])) ? $errors[$label] = 'Mandatory field, input required!' : NULL; if(!strlen($errors[$label])){ $valid = false; } } // insert data if ($valid) { $pdo = Database::connect(); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $sql = "INSERT INTO shoplist (store_name,item_description,qty_pkg,pkg_of,price,flyer_page,limited_time_sale,nos_to_purchase,shopper1_buy_flag,shopper2_buy_flag,purchased_flag,purchase_later_flag) VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"; $q = $pdo->prepare($sql); $q->execute(array($store_name,$item_description,$qty_pkg,$pkg_of,$price,$flyer_page,$limited_time_sale,$nos_to_purchase,$initialize_flag,$initialize_flag,$initialize_flag,$initialize_flag)); Database::disconnect(); header("Location: index.php"); }The following is the FORM portion of the code, which is where the logic for displaying the "error messages" is defiend <form class="form-horizontal" action="create.php" method="post"> <?php foreach($fields AS $field=>$label){ //Print the form element for the field. echo "<label>{$label}:<br>"; //If the field had an error, display it. if(isset($errors[$field])){ echo ' <span class="error">'.$errors[$field].'</span><br>'; } //Echo the actual input. If the form is being displayed with errors, we'll have a value to fill in from the user's previous submission. echo '<input type="text" name="'.$field.'"'; if(isset($values[$field])){ echo ' value="'.$values[$field].'"'; } echo '/></label>'; } ?> <div class="form-actions"> <button type="submit" class="btn btn-success">Create</button> <a class="btn" href="index.php">Back</a> </div> </form>Appreciate the help guys. Thanks Hey Guys. I have a custom function that simply loops through an array and outputs the menu categories it finds in the array.
The foreach loop passes the function an array and the function returns the the value. The problem is that the function returns that last value.
Now I know some of you might say ... "Why don't you put the foreach inside the function and return the value when the foreach loop has been completed"
The reason why is because I to use that foreach loop through another function as well. I was thinking about using globals to get the return value. But just wanted to get your perspective on the best option here.
Please let me know what you guys think Thanks

I am using a foreach loop to get the results of an array. My problem is that I need the results combined into one string. How can I accomplish this? Hi everyone, greetings from Brazil.
