PHP - Fetch Data
Okay so, I have always been curious, just never have taken the time to ask someone / learn what the differences are in fetches. What does mysql_fetch_array and mysql_fetch_row do thats different from each other? When pulling data from the database, would I like fetch array, or fetch row? or even fetch assoc? Thanks!
Similar TutorialsHello to all, I have problem figuring out how to properly display data fetched from MySQL database in a HTML table. In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table. The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'
Can someone help me on this, I guess the problem lies in the while loop? <thead> <tr> <th data-column-id="id" data-type="numeric">ID</th> <th data-column-id="email">Subscriber's Email</th> <th data-column-id="validity">Validity</th> <th data-column-id="valid_from">Valid From</th> <th data-column-id="valid_to">Valid To</th> </tr> </thead> Here is part of the PHP code:
<?php while($row = $stmt->fetch(PDO::FETCH_ASSOC)) { echo ' <tr> <td>'.$row["id"].'</td> '; while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) { echo ' <td>'.$row1["email"].'</td> '; } if($row["validity"] == 1) { echo '<td>'.$row["validity"].' month</td>'; }else{ echo '<td>'.$row["validity"].' months</td>'; } echo ' <td>'.$row["valid_from"].'</td> <td>'.$row["valid_to"].'</td> </tr>'; } ?>
Thank you. Hi, I am trying to fetch all data from database. but any data show twice. like this: Ali Ali 30 30 Osman Osman 20 20 Omer Omer 40 40 Salim Salim 10 10 Suzan Suzan 25 25 $mem_qry = "SELECT * FROM tbl_name"; $res = mysql_query($mem_qry); function mysql_fetch_all($res) { $return = array(); while($row=mysql_fetch_array($res)) { $return[] = $row; } return $return; } $all = mysql_fetch_all($res); foreach($all as $k=>$v) { foreach($v as $k2=>$v2){ echo $v2.'<br />'; } } Hi, I am quite new to PHP and to learn more about it I decided I would make a little project to easy my life a little bit I want to make a site that fetches lunch menus from the restaurants nearby my work. I would just like some help getting pointed in the right direction on how to make this happen Thanks! Br, Niklas Hi I have the following code works well However, if there is more than one record in the search result it shows the table lables on every record rather than just the one is it possible to have the table lables for just the result headings and not on each line after <?php require "header.php"; ?> <main> <link href="style.css" rel="stylesheet" type="text/css"> <div class="wrapper-main"> <div class="welcomelogged1"> <p>Searching For A Starter<p> </div> <form action="" method="post"> <select name="WeekComm" id="WeekComm"> <option value="Enter Week No To Search">Enter Week No To Search</option> <option value="WC 6th April">WC 6th April</option> <option value="WC 13th April">WC 13th April</option> <option value="WC 20th April">WC 20th April</option> </select> <input type="submit" name="Search" value="Search Starters"> </form> <?php $dBServername = "localhost"; $dBUsername = "root"; $dBPassword = ""; $dBName = "CandidateManagement"; mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT); $conn = mysqli_connect($dBServername, $dBUsername, $dBPassword, $dBName); if (!$conn) { die("Connection failed: " . mysqli_connect_error()); } if (isset($_POST['Search'])) { $WeekComm = $_POST['WeekComm']; $query = "SELECT * FROM contract where WeekComm='$WeekComm' "; $query_run = mysqli_query($conn,$query); while($row = mysqli_fetch_array($query_run)) { ?> <form action="" method="POST"> <table> <Tr><td><label></label></td> <td><label>Week Commencing</label></td> <td><label>First Name</label></td> <td><label>Last Name</label></td> <td><label>Start Date</label></td> <td><label>Client Name</label></td> <td><label>Action</label></td> </Tr> <tr> <td><input type="hidden" name="id" value="<?php echo $row['id'] ?>"></td> <td><input type="text" name="WeekComm" value="<?php echo $row['WeekComm'] ?>"></td> <td><input type="text" name="FirstName" value="<?php echo $row['FirstName'] ?>"></td> <td><input type="text" name="LastName" value="<?php echo $row['LastName'] ?>"></td> <td><input type="date" name="StartDate" value="<?php echo $row['StartDate'] ?>"></td> <td><input type="text" name="ClientName"value="<?php echo $row['ClientName'] ?>"></td> </tr> </form> <?php } }
I have attached a picture to show what i mean

I've been having an issue trying to parse text in a span cass with DOM. Here is my code example. try to extract some lines out of a webpage - with following technique: with the Extraction of values of attributes of elements with DOMDocument. Here is what i have gathered and learned:
$remote = "http://website.com/"; $doc = new DOMDocument(); @$doc->loadHTMLFile($remote); $xpath = new DOMXpath($doc); $node = $xpath->query('//span[@class="user"]'); echo $node;
and this returns the following
error -> "Catchable fatal error: Object of class DOMNodeList could not be converted to string".
And now - with this i need help.
What I am trying to do is parse the user name between this tag;
<div class="widget plugin-meta"> <h3 class="screen-reader-text">Meta</h3>
see more below:Here the concrete example view-source: https://wordpress.org/plugins/participants-database/ and https://wordpress.org/plugins/participants-database/
goal i need the following data:
Version: Last updated: Active installations: Tested up:
view-source: https://wordpress.org/plugins/participants-database/
Proceedings; i checked the source of the webpage. i tried to find out whether the texte is related to some kind of pattern.i have looked closely and found that all of them have class=”widget plugin-meta” . Well - This will make extracting them, a piece of cake. I tried with the code below helps to filter html elements based on values of attributes. but unfortunatley this ends up in a bad result; i need a helping hand and need to know how to parse the above mentioned data

Hi,
<?php $connect = mysqli_connect('localhost', 'root', '1234', 'contact'); $query ='SELECT * FROM tbl_employee ORDER BY ID DESC'; $result = mysqli_query($connect, $query); ?>

Hi. I am a little confused about PDO, its classes and the general oop aspects of it. If you at the below code:
<?php try { $handler = new PDO('mysql:host=127.0.01;dbname=app', 'root',''); $handlser->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); }catc(PDOException $e) { echo $e->getMessage(): die(); } $query = $handler->query('SELECT * FROM table'); while($r = $query->fetch(PDO::FETCH_OBJ)) { echo $r->message; }What's confusing me is that the fetch method is a method within the PDOSTATEMENT class so how come an object hasn't been created before hand in order to use the method? Furthermore it appears the method is a static method within the PDOSTATEMENT class so how come the double semi colon is being used such as: PDOSTATEMENT::FETCH? Any help would be appreciated. Thanks.

When the form data is sent via email I want the date/time the user submitted the information included in the email, mainly for records. Now, I thought using $_SERVER['REQUEST_TIME'] would work, but it is returning a value of "1320019222" in the email, any tips on how to fix this?? Thanks!!
