PHP - Retrieving Integers Using Regex From A Website Html Code
Hi, I'm trying to retrieve the integer value between the <span> tag from a HTML source code.
HTML source code:
<span> (3861822) </span>This is the php code:
<!DOCTYPE html>
<html>
<body>
<?php
//use curl to get html content
function getHTML($url,$timeout)
{
$ch = curl_init($url); // initialize curl with given url
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]); // set useragent
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); // max. seconds to execute
curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error
return @curl_exec($ch);
}
$html=getHTML("http://www.alibaba.com/Products",10);
preg_match("/<span>(.*)<\/span>/i", $html, $match);
$title = $match[1];
echo $title;
?>
</body>
</html>
Whenever I try to run it, this error will come out: Notice: Undefined offset: 1 in C:\xampp\htdocs\myPHP\index.php on line 19.
How to correct it so that it will display all the integer value within the tag name but without the bracket? Thanks
Edited by Raex, 20 August 2014 - 01:38 AM. Similar TutorialsI would like to display weather conditions on my website and store them in mysql database. I wonder if it is possible to load web page into php for parsing so the required info could be found and used? Is it doable with php and what functions could you recommend for this functionality? How can I have program running in the background on the server which would be triggered every so often to perform this task? Another question is if I want to trigger some action once a week like Tuesday at noon, is there function in php which could be used to check what day of the week and time it is ? I am new to website design so any help will be greatly appreciated. Hi,
I need to log into a website to check for the latest data, and I want to automate this with php script that will use a cronjob to log in, retrieve the data and email it to me.
Currently I'm stuck on the logging in part (I'm testing the script below on my squirrelmail email login page). I've tried using the snoopy php class (sourceforge.net/projects/snoopy/) but it seems the POST variables aren't being recognised (because the email program is directing me to the log in page, as opposed to telling me that my username/password is wrong).
(is it even possible for a servers to accept POST variables in this way??? I'm kind of surprised but lots of poeple seem to use snoopy to login via userforms)
Please could someone point me in the right direction?
Thanks,
Stu
/ load the snoopy class and initialize the object / $snoopy = new Snoopy(); / set some values / $login_form['login_username'] = 'MY_USERNAME'; $login_form['secretkey'] = 'MY_PASSWORD'; $snoopy->cookies['vegetable'] = 'carrot'; $snoopy->cookies['something'] = 'value'; / submit the data and get the result / $snoopy->submit('http://webmail.MY_WE...rc/redirect.php' $p_data); / output the results / echo '<pre>' . htmlspecialchars($snoopy->results) . '</pre>'; Edited by stubarny, 14 June 2014 - 11:27 AM. The PHP code sends me an email from the server, but the user input is empty or "blank". I only receive: "From: \ Email: \ Subject: \ Message: " and that's it. How do I fix my PHP and/or HTML code to receive user input from the form? Attached is my existing HTML and PHP code that doesn't send me any "user input" from the form. Thanks to anyone who can help!!
I am working on a kind of CMS for my own website which no one else will be using but me as a way of improving my php skills, and am having problems with retrieving data from the database that holds both text and php code. I have searched the web and found that i should be using eval() for the code to be executed before it is send to the browser but cannot get it to work and can't find my mistake(s). the php code will always be the same, and is supposed to retrieve the id number of a page to use in a link (and works fine when tested by loading the code directly without retrieving it from the database) this is an example of data stored in the database Code: [Select] The <a href="page_builder.php?id=<?php echo $page->id('mines_DwarvenMines') ?>">Dwarven Mines</a> have a great selection of Ores,... Of course when I leave it like this, hovering over the link in my page will show exactly that and lead to nowhere Code: [Select] localhost/page_builder.php?id=<?php echo $page->id('mines_DwarvenMines') ?> Most of these links appear in tips given at the end of the page and are processed as followed Code: [Select] $questtips = $quest->getQuestTips(); $tips = ""; if ($questtips == "none") { $tips = "/"; } else { foreach($questtips as $tip) { $tips .= "<li>"; $tips .= $tip->getTip(); $tips .= "</li>"; } } and finally put on screen by the presentation layer as followed Code: [Select] <h2>Tips & Extra Info</h2> <div class="tipsList"> <ul> <?php echo $tips ?> </ul> </div> I have tried all sorts to get the code to be executed when retrieved from the database before being send to the browser so that this particular link would say "localhost/page_builder.php?id=57" but I cannot get it to work, though I suspect it is fairly easy. I suspect I would have to store the data in a different format in the database? And how exactly do I use the eval() function in my case? Could someone please adjust my code so that it does work? Thanks I'm trying to pull up an identical form after submission by using its "id" and ECHO for the form lines. Question: What is the correct approach for ECHOing an HTML dropdown that is written as: <select name='chixcutlet' value='' > <option value='0.00' selected> --- </option> <option value='1.00'> 1 </option> <option value='2.00'> 2 </option> <option value='3.00'> 3 </option> </select> I want it to get the info from the database so that the option that is saved in the database will be new default when the page is loaded. If I don't change it to the previous info it will update the database with the default option rather then the actual option. Hi, I need to extract the integers from the source code:
<span class=CatLevel1><a onclick="Javascript:ShowMeu('21');">Arts</a> (9768)</span>
<span class=CatLevel1><a onclick="Javascript:ShowMeu('271');">Industrial Products</a> (9321)</span>
<span class=CatLevel1><a onclick="Javascript:ShowMeu('1273');">Baby</a> (11407)</span>
What are the pattern that I can use to retrieve all the integer in the bracket (9768, 9321, 11407)?
This is my php code:
<!DOCTYPE html>
<html>
<body>
<?php
$file_string = file_get_contents('http://www.lelong.com.my/');
preg_match('/<title>(.*)<\/title>/i', $file_string, $title); //pattern
$title_out = $title[1];
echo $title_out;
?>
</body>
</html>
Thanks
Edited by Raex, 22 August 2014 - 12:49 AM. I found the code below which checks to make sure something the user entered into a text field is an actual URL. I am looking to confirm that something a user enters is an actual link to an IMAGE, so does anyone know how I could adjust this code below to do that? Basically, this code below would accept http://monkeys.com AND http://monkeys.com/images/monkey.jpg. I want to alter the code so that http://monkeys.com would NOT be accepted since it's not an image. Essentially, I want to make sure whatever the user enters ends with .jpg, .gif or .png. Anyone know how to do this?

I am wondering how can I insert integers in the database without manually input it in the form. I am looking to fill the product_id and customer_id table. I would do it but only by sequence and '' quotes at the VALUE part of an INSERT statement. Also condition the insert of product_id and customer_id according to the id in the SESSION variable. Code: [Select] <?php session_start(); if (isset($_SESSION['id'])) { $userid = $_SESSION['id']; $username = $_SESSION['username']; $fname = $_POST['firstname']; $lname = $_POST['lastname']; $telephone = $_POST['telephone']; $city = $_POST['city']; $state = $_POST['state']; $itemname = $_POST['product_name']; $price = $_POST['price']; $details = $_POST['details']; $category = $_POST['category']; $subcategory = $_POST['subcategory']; $product_id = $_POST['product_id']; $customer_id = $_POST['customer_id']; $date_sold = $_POST['date_sold']; $sqlinsert = "INSERT INTO customers (id,firstname,lastname,telephone,city,state,product_name,price,details) VALUES('','$fname','$lname', '$telephone','$city','$state','$itemname','$price','$details')"; $sqlinsert2 = "INSERT INTO products (id,product_name,price,details,category,subcategory) VALUES('','$itemname','$price','$details','$category','$subcategory')"; $sqlinsert3 = "INSERT INTO sales (id,product_id, customer_id, date_sold) VALUES('','$product_id','$customer_id','$date_sold')"; $enterquery = mysql_query($sqlinsert) or die(mysql_error()); $enterquery2 = mysql_query($sqlinsert2) or die(mysql_error()); $enterquery3 = mysql_query($sqlinsert3) or die(mysql_error()); } ?> The above insert its respective fields in each table but how is it possible to INSERT it according to the SESSION['id]; so that it INSERT according to the costumer id plus that it generates and INSERT automatically in the product_id and customer_id related to the product_id and customer_id fields in products and customer table? without manually doing it. any references will be appriciated because the above code seems like the product_id and customer_id won't INSERT in relations to the customer and product table. One more thing the product_id and customer_id won't be pass from the form to this file but rather a value will be INSERT it in their field according to the id in customer and products table. Is it possible to perform type declaration which allows either an integer or a string digit (i.e. ctype-digit) instead of the following?
function someFunction(int $id){}
Looking at functions.arguments.type-declaration, I expect not. If not, would you recommend type casting before calling the function or removing type declaration from the function and performing the check manually within the function and throwing an applicable exception? Thanks I almost have this right, but not quite. I am trying to echo out the average score if a person scored above 70 and my averaging isn't correct. It should echo out 89, but instead the number is 63.25. The averaging is the only part not working. Everything else works as intended. I might not have my curly braces in the proper order or something. I think it's something stupid I am forgetting. Here is my code. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Array Test</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <?php function array_average_nonzero($scores) { return array_sum($scores) / count(array_filter($scores)); } $scores["Tim"] = 98; $scores["Tom"] = 80; $scores["Mike"] = 50; $scores["Jason"] = 25; foreach( $scores as $key => $value) if($value < 70){ echo "$key scored a $value which is less than 70. <br />\n"; } elseif ($value < 70); { echo "The average score of those who scored over 70 is: " .array_sum($scores) / count($scores) .

Hi,
Is there any way to use the inbuilt filter functions in PHP to filter for integer values greater than 256? All examples that I saw had a max_range of 256. Kindly suggest. Thanks.
Hi everybody, a few dasy ago i found a function which translates integers into text like this:
echo $number->written_number(101); // one hundred one
but i've got a problem, this function works fine on russian language, but that this function translate in 3 languages:
russian, english and ukrainian like this:
echo $number->written_number(101); // сто один - one hundred one - сто один
how can i add english and ukrainian languages?
When i tried to add this manually, it was okay but in one moment i received error, and all my script is broked, and now i don't know what to do, i've got a few hours to complete this test work, but unfortunately i've got no idea how to do this(
Pls help me somebody, i will infinitely grateful!!!

So I'll do my best to explain it here. I have a pull down menu as part of a form, which contains the months of the year. I'm trying to store the value of this form entry using the $_POST['month'] variable into a database but first, I need to convert the month values into their corresponding integer values( that is 1 for January, 2 for February etc), in order to easily do date calculations later down the road. Any ideas about how to do this? It may be helpful to include the code for the pull down menu. Code: [Select] <p><tab> Date of Birth: <?php //Make the month pull down menu. //Array to store months. $months = array (1 => 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'); print '<select name= "month">'; foreach ($months as $key => $value) { print "\n<option value=\"$key\">$value</option>"; } print '</select>'; ?> </tab> <tab> <?php //Make the day pull down menu print '<select name= "day">'; for ($day = 1; $day <= 31; $day++) { print "\n<option value=\"$day\">$day</option>"; } print '</select>'; ?> </tab> <tab><?php //Make the year pull down menu print '<select name= "year">'; $start_year = date('Y'); for ($y = ($start_year - 18); $y >= 1900; $y--) { print "\n<option value=\"$y\">$y</option>"; } print '</select>'; ?> </tab> </p> Hi Guys. Really Stuck here. I am making a website, its basicall an online shop of sorts. I am making a login page for our customers and an admin page for us lot to upload new products to sql etc. Whats its meant to do is accept the username and pw then allow me to access the adminpage. Although its just saying that user doesnt exist all the time. I dont know why becuase the details are correct. admin_login page is the code below. <?php session_start(); if(isset($_SESSION["manager"])){ header("location:index.php"); exit(); } ?> <?php if(isset($_POST["username"])&&isset($_POST["password"])){ $manager = preg_replace('#[A-Za-z0-9]#i','',$_POST["username"]); $password = preg_replace('#[^A-Za-z0-9]#i','',$_POST["password"]); include"../storescripts/connect_to_mysql.php"; $sql = mysql_query("SELECT id FROM admin WHERE username='$manager' AND password='$password' LIMIT 1"); $existCount = mysql_num_rows($sql); if($existCount == 1){ while($row = mysql_fetch_array($sql)){ $id = $row["id"]; } $_SESSION["id"] = $id; $_SESSION["manager"] = $manager; $_SESSION["password"] = $password; header("location: index.php"); exit(); }else{ echo 'That Information Is Incorrect. Try again <a href="index.php">Click Here</a>'; exit(); } } ?> and now the index.php which is what the admin see when they log in successfully. <?php session_start(); if(isset($_SESSION["manager"])){ header("location: admin_login.php"); exit(); } //Be Sure To Check That This Manager Session Value Is Infact In The DataBase $managerID = preg_replace('#[^0-9#i','',$_SESSION["id"]); $manager = preg_replace('#[^A-Za-z0-9]#i','',$_SESSION["manager"]); $password = preg_replace('#[^A-Za-z0-9]#i','',$_SESSION["password"]); include "../strorescripts/connect_to_mysql.php"; $sql = mysql_query("SELECT * FROM admin WHERE id='$managerID' AND username='$manager' AND password='$password' LIMIT 1"); $existCount = mysql_num_rows($sql); if($existCount == 0){ header("location:../index.php"); exit(); } ?> I have the following code in html: <html> <head> <script type="text/javascript"> <!-- function delayer(){ window.location = "http://VARIABLEVALUE.mysite.com" } //--> </script> <title>Redirecting ...</title> </head> <body onLoad="setTimeout('delayer()', 1000)"> <script type="text/javascript"> var sc_project=71304545; var sc_invisible=1; var sc_security="9c433fretre"; </script> <script type="text/javascript" src="http://www.statcounter.com/counter/counter.js"></script><noscript> <div class="statcounter"><a title="vBulletin statistics" href="http://statcounter.com/vbulletin/" target="_blank"><img class="statcounter" src="http://c.statcounter.com/71304545/0/9c433fretre/1/" alt="vBulletin statistics" ></a></div></noscript> </body> </html> Is a basic html webpage with a timer redirect script and a stascounter code. I know a bit about html and javascript, but almost nothing about php. My question is: How a can convert this html code into a php file, in order to send a variable value using GET Method and display this variable value inside the javascript code where says VARIABLEVALUE.
