PHP - Convert Loop Foreach Results To A Variable String
Hello, i have the code below and i need to have all results in a variable as a string, inside the loop they are displayed how i want but outside will echo the last result. Thank You.
Code: [Select] foreach($_POST as $key=>$value){ if (is_numeric($value)) { $valoare = "$value,"; } } echo $valoare; Similar TutorialsI am using a foreach loop to get the results of an array. My problem is that I need the results combined into one string. How can I accomplish this? I have a search form that has a drop down Code: [Select] <select name="radius" id="radius"> <option value="5">5 mi.</option> <option value="10">10 mi.</option> <option value="15">15 mi.</option> <option value="20">20 mi.</option> <option value="50">50 mi.</option> <option value="100">100 mi.</option> </select> I'm trying to limit the results in a foreach loop within what was selected. Meaning, if someone selects 10, results within 10 miles will show The foreach is Code: [Select] foreach ($stores as $k=>$v) { $output = "<h3 style='margin:0;padding:0'><b>".$storeinfo[$k]['MktName']."</b><br>(approx ".$v." miles)</h3>"; $output .= "<p style='margin:0 0 10px 0;padding:0'>".$storeinfo[$k]['LocAddSt']."<br>"; $output .= $storeinfo[$k]['LocAddCity'].", ".$storeinfo[$k]['LocAddState']." ".$storeinfo[$k]['zipcode']."</p>"; print_r($output); } $v being the distance. So I need to show only the results of $v that are less than $r. How would I go about doing this? Right now, $v displays numbers like 5.04, 173.9 and so forth. Can anybody help me out? Thanks in advance. Hello dear community, good day! first of all: Merry Christmas to all of you!! How to combine / concatenate a *divided* string in order to use this combined / concatenated string in a loop where i run the $dom = new DOMDocument(); @$dom->loadHTMLFile('<- path to the file-> =60119'); and the following.... numbers - Note: they replace the ending!!! 60299 64643 62958 63678 60419 60585 60749 60962 and so on. ( Question: How to combine the string (in fact the string is an URL) so that i am able to build the URLs automatically. And that i am able to run all that in a loop - eg with foreach [probably this is the right way to do that]. I hope that i was able to explain the question so that you understand it. If i have to be more descriptive - just let me know! Many many thanks for a hint! db1 Hello. I'm trying to append the loop keys and values into a string and store it into a hidden field. This is the code I have : Code: [Select] if (isset($_POST['ordered'])) { // We can assign $_POST['product'] to a variable to make it easier to type out $prod = $_POST['product']; // Throw a little intro to see how many they checked echo 'You selected ' , count($_POST['ordered']) , ' products.'; // Now we loop through it and get the IDS that were selected // Foreach lets you select the $key and the $value for each iteration of the loop // $strOrder = ""; foreach ($_POST['ordered'] as $key=>$id) { echo '<p/> ProdName: ' , $prod[$id]['name'] , '<br/> ProdPrice: ' , $prod[$id]['price'] , '<br/> ProdQty: ' , $prod[$id]['qty'] , ' <hr/>'; $strOrder .= $key . " " . $id; $TOT += $prod[$id]['price'] * $prod[$id]['qty']; } $TOT2 = $TOT + 55; echo '<input type="hidden" Name="TOT" value ="'. $TOT .'">'; echo '<input type="hidden" name="TOT2" value =". $TOT2 .'">'; echo '<input type="hidden" name="Order" value=". $strOrder . '">'; } strOrder does not get set to a value.
//$value1 = $_POST['game'];

} elseif (strpos($value1, '9')) {
$num = '9';
}
$gm7hodds = $games[41]["BP"];
$gm7aodds = $games[40]["BP"];
$gm8hodds = $games[47]["BP"];
$gm8aodds = $games[46]["BP"];
$gm9hodds = $games[53]["BP"];
$gm9aodds = $games[52]["BP"];
/*
$getratio = $num + $team;
echo $getratio;
Team is not a math operation so I'll finesse that later.
*/
$findratio = 'gm' . $num . 'h' . 'odds';
echo $findratio;
gm7hodds
How would I add the $ to it and return its array value $gm7hodds? Solved whoops -> echo eval('return $'. $findratio. ';'); Edited April 28 by Minzersolved Hi I have an array of items that I am currently displaying a foreach loop What I'm looking to do, is add a string, to all of items, a part from the last 4: foreach ($pager->getResults() as $items => $item) { echo $item->getName(); //need to add a string to this for the all but the last 4 } Thanks This is more of a technical question that i could not find the answer to pn the php.net manual pages. take the folowing example code: foreach ($array as $key => $value){ $tempvariable = some_property_of($value); } unset($tempvariable); is that unset statement needed? Does PHP automatically destroy the variables once the foreach loop is left? I'm trying to take a number of items from a database using a while loop and put the results into a variable so that I can send one email with all the results. I'm having trouble figuring this out though. Can anyone please give me any ideas as to how to make this work? Here's what I've done so far... all it does is result in an email with the first set of results in the while loop, not all of them. Code: [Select] <?php include("conf.inc.php"); $result = mysql_query("SELECT `to`,`from`,`subject`,`message`,`date` FROM allmsgs WHERE reported = 'n' ORDER BY `messid` ASC"); $row = mysql_fetch_row($result); $cdate = date('m-d-Y'); $sendto = "List@emails.here"; $emailsubject = "Webstats Report For $cdate."; while ($row = mysql_fetch_row($result)) { $to = $row[0]; $from = $row[1]; $subject = $row[2]; $message = $row[3]; $datetime = $row[4]; $eachmessage = "<p> <table width=\"400\"> <tr> <td> <hr width=\"400\"> To: $to<br> From: $from<br> On $datetime<br> <br> $subject<br> <br> $message </td> </tr> </table> </p>"; } $emailmessage = "<html> <body> <p>Here is a list of the messages that have been exchanged in the last 24 hours using the webstat system system.</p> $eachmessage </body> </html>"; // To send HTML mail, the Content-type header must be set $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n"; // Additional headers $headers .= 'From: Webstats <reports@webstats.com>' . "\r\n"; // Mail it mail($sendto, $emailsubject, $emailmessage, $headers); ?> Hi Guys Ever had the feeling your being a spoon and can't see the wood for the trees? Well, that's how I feel today. All I am trying to to is implement a variable in a "foreach" loop that increments by one through each iteration of the loop. I know how to do it in a "for" loop but can't for the life of me get it to work here. Here is the code: foreach ($cart as $prodcode => $qty) { $item = get_product_details($prodcode); echo '<input type="hidden" name="item_name_'.[b]$needavariablehere[/b].'" value="'.$item['description'].$_SESSION['finish'][$prodcode].$_SESSION['handles'][$prodcode].'" />' . "\n"; } Where I have highlighted $needavariablehere is where I want a number to appear i.e. if there is one item available and the foreach loop iterates once I want the number 1 here. If there are two items and the foreach loop iterates twice I want the output to have number 1 in the first line and number 2 the second time around and so on. How many times the foreach loop iterates is based on the $cart array which contains items in a shopping cart. Thanks for any help you can give guys. Below 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? I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong! The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match) The if loop displays ALL listings with the same name (counts them all) so there are no unique listings! <?php $posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'"; $posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!"); /* While Loop */ while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } /* For Loop */ $posts_by_city_row = mysqli_fetch_array($posts_by_city_results); for ($i=0; $i<sizeof($posts_by_city_row); $i++) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } ?> Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below): AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners How can I limit my foreach to displaying three results?

Hello everyone !
I am currently developing a module for my site that will allow me to classify each solution to help a disability by type. Type : Visual disability Solution : Add screen readers For this, I have a database in which these types and solutions are found. In this database, the solutions of one type or another are not in a defined order. They can be put randomly, when a user adds one. I need to display, in a table, these Types first (as a title), then the solutions corresponding to this type. I manage to generate a display thanks to a foreach loop, but my solutions are all mixed up and therefore not clearly sorted.
Visual disability
Audio-described cut-scenes
Highlighted path to follow
Sensitivity settings for all the controls
Screen readers on menus
Slow down the game speed
But I would need it to look like this:
Visual disability
Audio-described cut-scenes
Highlighted path to follow
Screen readers on menus
Slow down the game speed
Physical disability
Sensitivity settings for all the controls
In my example above, only the solution "Sensitivity settings for all the controls" is part of the "Physical disability" type. The rest is part of the "Visual disability" type. Here is the code I currently use to retrieve my information from my database and display it. It's a Wordpress.

Thank you in advance for all the help you can give me! Edited January 13 by Sagaroth Hello all. I am very new to PHP, and I am not sure where to look or what I'm looking for in my current assignment. My task is to take in two numbers between 0-100. Once I take in that number, it should state beside it "The __ was accepted." The program should not accept any numbers greater than 100 or any characters. Once I do this, I must take a second number and do a similar thing. Finally, I must have a statement show up at the bottom stating which number is greater. Essentially, I need help in determining what I should use to place parameters, and how I can keep the program from echo ing any statement until input has been taken and tested for parameters. Any help you can provide will be greatly appreciated! how can i convert string type into integer like when using parseInt in javascript...however i use (int)$string but not working i have this $string1="10"; $string2="5"; and i wish to add both string ....using (int) still treat $string1 and $string2 as string so i get 105 as a result instead of 15
<?php
$srs = array();
for ($section = 1; $section < 5; $section++) {
for ($row = $section; $row < 10; $row++) {
for ($seat = $row; $seat < 20; $seat++) {
$srs[] = array(
'section_name' => $section,
'row_name' => $row,
'seat_name' => $seat);
}
}
}
output(convert_array($srs));
// Converts the array
function convert_array($input)
{
return $input;
}
function output($obj)
{
echo "<pre>";
print_r($obj);
echo "</pre>";
die;
}
?>
I'm trying to convert those array number to string, add implode() to make it happen, but seem PHP didn't recognize variable in $input. Like this implode("Section: ", $input) or (Section: ", $srs). Can you help me? Thanks, Gary Edited October 16, 2019 by sigmahokiesHi everybody, I need some help about how to convert string to array name. I have the following function which pass $_REQUEST type as parameter. It is not working because I don't know how to convert $method to $_GET or $_POST in a proper way. Do anybody know how? Code: [Select] function validateIfFilled($method, $fields) { $exploded=explode(",",$fields); foreach($exploded as $field){ if(empty($method[trim($field)])){ return false; } } return true; }; if(!validateIfFilled('$_GET', "email, password, address")) ... Thank you! I have a form that submits G How can I convert this to string of time when I need to insert it into the database and then turn it back around when it needs to be read? <option>11:00 AM</option> <option>11:30 AM</option> <option>12:00 PM</option> <option>12:30 PM</option> <option>1:00 PM</option> <option>1:30 PM</option> Thank you. |
