PHP - Simple-html-dom - Quick Question
I have a quick question to ask, as i cant see it in their docs. Maybe you can help me.
I am using http://simplehtmldom.sourceforge.net/ Right, i have written a Simple HTML Dom script to collect data from this page, as an example: http://www.visualdesign.ie/_dev/myscraper/simplehtmldom/dev-env/scraping/daily/daily.html Script executed by running a cron job on this file (which generates the XML): http://www.visualdesign.ie/_dev/myscraper/simplehtmldom/dev-env/scraping/daily/daily.php The data is collected, and written to this file in XML file: http://www.visualdesign.ie/_dev/myscraper/simplehtmldom/dev-env/scraping/daily/daily.xml Thats is fine, and the script essentially scrapes the entire page, with no conditional IF's for any sections. A sample of my code for one segment is below: http://pastebin.com/JLb8f92N What i would like to do now, and i am hoping you could help out is... Scrap this same page, but produce seperate XML files, based on the date. So if you view that page, i want to scrape the data in the table Saturday 4th February 2012 and produce XML for for that day only. The i want to scrape the data in the section for Sunday 5th February 2012, and another for Tuesday 7th February 2012. I think its self explanatory. The table date sections are separated by this HTML element: bg color = " #CCCCCC " But bare in mind that the table rows on each date section will change when the site is updated, and there may be additional or less football game records. Anyway, i would appreciate any help you can show me, on how to place in any conditionals in the code, and only scrape the date sections needed. Separate script files would be fine if it was needed. Many thanks for your time, Darren. Similar TutorialsHey guys, Why exactly do people use multiplication when calculating time? Like when setting cookies, timeouts or something that requires second-based definitions. For example, some do: Code: [Select] $thirty_days = time()+60*60*24*30; As opposed to what I do: Code: [Select] $thirty_days = time()+2592000; Why do they do that? Does it help them calculate it without a calculator? Make it easier to manage/adjust in the future? Personal preference? These are the only possible explanations I can think of. This has been bugging me for a while...am I doing something wrong? I need to use a HTML form to retrieve data in a certain order of ascending/descending using a drop down box and a true/false statement button for one of the values from a MySQL database. Im guessing I need a php script to query the database, but can I add the php code to the HTML or upload a php to the server that links the HTML thank you Hi, I m doing some work for my self an because of that i been reading a lot arround about PHP, and theres something that i would like to ask a bit of enlightenment. So my question is as the title says about html form's using php to insert data into mysql, i been reading tutorials arround the interwebs and even made afew successful tests, but pretty much all tutorials use 2 files to accomplish this the html file with the form and an insert.php where the actual code is stored so this made me think is this how usually it's done? in over all you will have 1 file for the form, 1 for the insert, 1 for the edit php code and 1 for delete. How do you guys usually do it? PS: one of the tests i did was making 1 single file with all these using an switch. My interest in making this question is solo to learn how other people do it to see if i m in the right way. Thanks in advance. Hi I need someone to fix a bug I have and to "speed up" the loading of the image by having the firs x number of images load first then loading more after they finish.
The bug should be easy to fix as I have a working copy of the page minus the change I made. The problem is since I updated to code the other part wont work (
contact me for more details and let me know you how much you would charge.
Thanks,

How do i display an image from my directory?!? :S I don't mean to be lazy and just ask people on here, I have researched it online but can't seem to find a quick simple answer. Thanks People!! hey guys i have a script that creates a cookie named "MyLoginPage" now everything works well the cookie is saved and it keeps the user logged in The Question ok so im wanting to create a link that will delete the cookie so when the user clicks the link it will delete the cookie is this possible?? if so, how?? many thanks I am starting to learn PDO by re-writing one of my existing scripts. Do I still need to validate $_GET or does PDO do the work for me? Currently I am using: Code: [Select] $id = $_GET['id']; $sth = $dbh->prepare('DELETE FROM van_reservations WHERE id = :id'); $sth->bindParam(':id', $id, PDO::PARAM_INT); $sth->execute(); I used to validate by using this: Code: [Select] $id = isset($_GET['id']) && is_numeric($_GET['id'])?(int) $_GET['id']:0; Hi, I've seen code like this multiple times, but I don't really know what it means. function funcName(&$something) { // whatever } What exactly does the "&" do before the variable? Does storing multiple values in 1 database field with a varchar let's say set at 150, all separated by "|'s" so I don't have to create a field name for each one is it better performance wise or no? (storing 6-7 different |'s that will be outputted with a array ofc) ? how to open a site with curl that has frames ? when ive tried it gives "your broswer does not support frames" ... hey! I have a site where I want to use multiple issets at the same time, like if I have four buttons and four issets: if(isset($_POST['one'])) { echo '<div class="example_box">one</div>'; } if(isset($_POST['two'])) { echo '<div class="example_box">two</div>'; } if(isset($_POST['three'])) { echo '<div class="example_box">three</div>'; } if(isset($_POST['four'])) { echo '<div class="example_box">four</div>'; } but for some reason it seems like only one isset can be activate at a time, is there any way to work this out or something :s? I've tried some variants of elseif stuff and such, but yeah, I'm pretty new at this stuff hi. when i get into some function manual and there is a note says. Quote This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged. . is that meaning that after 5.3.0 version this function will not be supported? thanks , Mor. code <?php //storecodefound.php v1.0 //purpose is to store the http refer and the code associated with the site to a db to be collected and verified by submitcode.php $code = $_GET['code']; $site = $_SERVER['HTTP_HOST']; //check to see if the code already present $connect = mysql_connect("localhost","root","") or die (mysql_error()); $check = mysql_query("SELECT code FROM hunter.codes WHERE code='$code'") or die (mysql_error()); $row = mysql_num_rows($check); echo "result of \$row is ".$row; echo "<br />"; if ($row = 0) { //insert into db cause it's not there mysql_query("INSERT INTO hunter.codes (id, code, site) VALUES ('','$code','$site')") or die (mysql_error()); } else { //echo it's already here echo "Code already found on server!"; } ?> my question is the result of $row is infact 0 and the if statement says if $row is 0 to insert into db and instead it's given me the code is already found? What is the difference between these two lines Code: [Select] !isset($_POST[$requiredField]) and Code: [Select] !$_POST[$requiredField] Is there a way to only output the first, say, 30 words of a variable? I have a way to do it in mind, but seems like it's messy and not practical. Any suggestions? E.g: WITHOUT LIMIT: Welcome to my store. Would you like to buy something? We have really good noodles and fishes in doodle pools. WITH LIMIT: Welcome to my store. Would you like... Sort of like a short preview. Hello everyone, With the recent time change, I found a new problem with my code. I think I have it fixed by utilizing the "date_default_timezone_set()" function, but I have a question. Does this php time/date function automatically account for daylight savings time, is it something that will have to be adjusted in my code? I think I can figure out how to adjust it if it's needed, but I don't want to have to do the work if it is updated automatically. Thanks for any help. Say, Code: [Select] $ok = 'ABCDEFG' What is the command to check whether $ok contains 'C'? Can I replace the set message text for $body and $subject with $_POST['message']; $_POST['subject']; so I can get a users input from a html form via php as the action. Instead of the set text in the script. As seen http://email.about.com/od/emailprogrammingtips/qt/PHP_Email_SMTP_Authentication.htm Hello, If we have large amount of data we always use SCP to copy data from remote server. scp -P 100 user@192.168.2.3: /home/user/folder /home/user1/folder/. But if DSL (Internet) of local computer disconnects I observed failure of transfer many times and this whole process becomes irritating. Is there any alternative way to use scp or rsync with php so that we can execute it with script ? Something like this ? <?php // Having shell access but its not working 4 me... $conn = ssh2_connect('ftp.server.com', 100); ssh2_auth_password($conn 'user', 'pass'); ssh2_scp_send($conn, '/local/filename', '/remote/filename', 0644); ?> Another question is there any way we can run such code with the help of shell_exec() or is this implementation is secure? Thanks in Advance! quick question... I have a column in my table called views. I want to reset the column to 0 for each row in the table. What's the easiest way to do this? |
