PHP - Read Random Lines From A Record
Hello, i will keep it simple to understand :
1) i have a database with 2 columns - word and text 2) Each word has approx. 600,000 lines of text associated with it. 3) Iam a .net person shifting to php and mysql - so a little knowledge. MY requirement : 1) I will pass the word through a form 2) The form will connect to the database and should display 2000 random lines from those 600,000 which should be non-repetitive My current progress : Code: [Select] <?php $con = mysql_connect("localhost","text_minx","pwd"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("my_db", $con); $result = mysql_query("SELECT * FROM Data WHERE word='health'"); while($row = mysql_fetch_array($result)) { echo $row['lines']; echo "<br />"; } ?> This shows all the lines. What i want is to read this $row['lines'] in a possible array and randomly select 2000 lines from it - and they should be non-repetitive. Any help please? Similar TutorialsHi Everyone, This is Tamilmani Mohan , i have an issue in to read the SP record set result by using SQLSRV queries. Sample PHP code is <?php $para = array(array($memberid,SQLSRV_PARAM_IN), array($start_date,SQLSRV_PARAM_IN), array($end_date,SQLSRV_PARAM_IN) ); $stmt = "{call MemberStatement(?, ?, ?)}"; if(!($result= sqlsrv_query($conn,$stmt ,$para))) { echo "Database Error"; die; } $arr_main = array();$totalpoints =0;while($row = sqlsrv_fetch_array($result)){ $arr_main[] = $row;$totalpoints = $totalpoints + $row['member_points']; }?>() When i execute the above i don't get any result. But if i run the above SP in management studio , i am able to see the result(8 rows are coming). I don't know the reason , why i don't get any result? Please any one give me the solution for this problem. Regards Tamilmani Mohan Hi, I am learning pdo php and mysql
I would like to know how to see whether a record has been read or not. I have a database messages with id, user_id, contact_id, login, msg, rrecord and msgtime.
The rrecord column has been set as 0 as default. When the client clicks the msg link, I would like it to update the rrecord to 1.
Thanks.

Thanks! I have a MySQL database with each record of a person who has registered for an event, I am displaying the information on a web page for a user, but he wants to be able to print out all the records in alphabetical order by last name, first name later on so he will have a hard copy of each person who has registered at the table when they arrive. How can I write each record to a Txt file that he can print out later that will be formated with the record contents along with each fields definition (Ex. Last Name - Smith, First Name - John, etc)? Hello,
I try to get website speed of some website, but i can read only ''domain.com'' i can't read website files like css , js ... why ? i use proxies for this job.
here is the php code:
$options = array(
'useragent' => "Firefox (+http://www.firefox.org)", // who am i
'connecttimeout' => 120, // timeout on connect
'timeout' => 120, // timeout on response
'redirect' => 10, // stop after 10 redirects
'referer' => "http://www.google.com",
'proxyhost' =>'85.25.8.14:80'
);
$response = http_get("http://solve-ict.com/wp-content/themes/ict%20theme/js/jquery-1.7.1.min.js", $options , $info);
but it works fine with http://domain.com/ , but with files css or js it gives 404, using some free proxy servers available
?
Thanks.
Hi
I try to echo out random lines of a html file and want after submit password to whole content of the same html file. I have two Problems.
1st Problem When I echo out the random lines of the html file I don't get just the text but the code of the html file as well. I don't want that. I just want the text. How to do that?
for($x = 1;$x<=40;$x++) {
$lines = file("$filename.html");
echo $lines[rand(0, count($lines)-1)]."<br>";
}
I tried instead of "file("$filename.html");" "readfile("$filename.html");" But then I get the random lines plus the whole content. Is there anything else I can use instead of file so that I get the random lines of text without the html code?P.S file_get_contents doesn't work either have tried that one.
2nd Problem:
As you could see in my first problem I have a file called $filename.html. After I submit the value of a password I want the whole content. But it is like the program did forget what $filename.html is. How can I make the program remember what $filename.html is? Or with other words how to get the whole content of the html file?
My code:
if($_POST['submitPasswordIT']){
if ($_POST['passIT']== $password ){
$my_file = file_get_contents("$filename.html");
echo $my_file;
}
else{
echo "You entered wrong password";
}
}
If the password isn't correct I get: You entered wrong password. If the password is correct I get nothing. I probably need to create a path to the file "$filename.html", but I don't know exactly how to do that.
Trying to get this done: Page_1 has many external links, when certain links are clicked i do not want user to go directly to page, but rather go to a special add page_2 where user must click a second time on the link to finally get there. The add page_2 must show on screen the name of the initial link from page_1, it must change accordingly with the link it came from page_1,once on page_2 the hyperlink redirects outside the site. So far i am thinking give an id to the div or "<a href..." on page_1 then somehow have page_2 detect that id and fill in the variable for the final external link. Other wise is there a way to detect a url from incoming? I guess a similar example is how some domain name sellers landing page will indicate the name of the site. Such as "Thisdomain.com" is for sale. same landing page but the name changes according to the domain that was typed. As above, I have a lottery style site that picks a random number between 1-8 but my users complain for some reason that this is not enough. So i was told to look into using fopen and random.org to generate a random number. Anyone have experience of this and perhaps a code snippet for me to look at and possibly use? help will be appreciated. I got a question im using izabi for me im one who loves the software. But there some quirks that they forgot to add when making the mail system. I was wondering how it would be possible to code in a peice of php where it says read after someone read the email. If you need a copy of the mail mail script let me know. hey guys i have to following code <?php include("users/index.php"); ?> <?php $LOGIN_INFORMATION = array( $user_login_username => $user_login_password, ); ?> the script connects to the database and fetches the data the problem im having is the table has 3 tables "ID" - "user_login_username" - "user_login_password" in those tables are 2 entries "1" - "test" - "user" "2" - "test1" - "user1" now on the login screen when i enter the username and password "test1" and "user1" it logs me in fine and works how i want it to but when i enter "test" and "user" it doesnt work if i add another entry so the table shows "1" - "test" - "user" "2" - "test1" - "user1" "3" - "test2" - "user2" and i try the to login again with "test" and "user" it fails and so does "test1" and "user1" but "test2" and "user2" works the script is only fetching the last entry from the DB is there anyway to login with any user in the DB?? if this dont make sense or you need more info please ask Thanks My current code (which works): Code: [Select] <?php $body = explode("\n", $body); $body = array_slice($body, 3); $body = implode("\n", $body); ?> Is there a better way of doing this, so I dont have to explode and implode an array just to accomplish this? Hello, I'm creating a program that analyzes information that is exported by another program. That program exports it in this way: Value1 Value2 Value3 Value4 Value1 Value2... In order to insert them in the database, I first have to know how many lines are inserted. They get send through HTML post. I already tried: $lines = explode("\n", $string); $number_lines = count($lines); But this always results in 1. How do I fix this? Regards, Chris Can you please tell me what each of these lines of code means?
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = strtolower( end($temp) );
$length = 20;
$newfilename = $_SESSION['user_id'].$_FILES["file"]["name"];
$thumbnail = $newfilename . "." . $extension;
move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $thumbnail);
$sql = "INSERT INTO videos ( filename ) VALUES( $thumbnail )";
mysql_query($sql);
$file_location = '<a href="http://www.--.com/upload/' . $thumbnail . '">' . $thumbnail . '</a>';
$description = $description . " \n " . $newfilename;
Good morning, I passed a bunch of HTML tags over a function that delete then, keeping just the text between. The problem is, after that all the tags were replaced by line breaks. Something like this before the function: <tr> <td> Text </tr> </td> After the function the 4 tags were correctly removed but instead i receive just the string "Text" I receive 2 line breaks, the "Text" and other 2 line breaks, like this: Text In HTML code this line breaks has no tags like <br> or <p> it's just blanck lines. I need to get just the text, how can I get rid of then? I tried this and also didn't work. $text = str_replace("/n", "", $text ); Thanks Danilo Jr. I'm trying to update records in a Db. I have a record called "classOffering" and I have associated records for that offering called "classSessions". You have 1 classOffering for 1 to 6 classSessions. The process I use has the user create the classOffering and say how many classSession there will be then I create how ever many sessions they say. I then display the classSessions so they can be edited and updated in the Db. I can't seem to update and set more than one record even though there are more. I know I need to use a while or foreach statement, but I can't seem to do it. Here's my code so far: $sessSet = "UPDATE classSessions SET startDate= '$startDate', startTime= '$startTime', time= '$time' WHERE classSessions.sessionId = $sessionId "; Thanks for any help. Is it no problem to give the SUM of integers in a column, but is it also possible to give the SUM of integers in a record (automatically)?
I have a task that seems to be complex.
Short Description: currently users of the application I am hired to develop have two steps to do when using the app:
1. Select a Product Line (A, B, C, D)
2. Select input parameters for that product line - all product lines have simlar "Main" input parameters, but also each line has its own special features that can be selected.
3. Selections for that product line are shown - the result is a long table or options for that particular product line. Things like price, discounts, product specifications, etc.
What the users want now is this:
1. Select input parameters (not sure how to handle individual product lines special parameters yet)
2. Selections for all product lines are shown
The code base is legacy code, with code thrown around everywhere. One idea me and my coworkers have been considering is a complete rewrite, since it will help us with writing tighter code, and do what the customer wants. But that will also take time, and there is no spec. The spec is in the code mess.
Another one is I am considering now is a "merge". Somehow merge the product lines, since we have the separate product modules (A, B, C, D), there must be a way to consider maybe extending one to include the others, or somehow get me to the end result -- allow users to see selections for all product lines.
Do you have any experience, any suggestions on how to do this? I know this needs details, and details are in my code that you don't see, and most likely won't have the time to read and understand anyway.
But I am looking for any ideas or encouragement though that may help. And my question is -- is there any kind of procedure or technique or something to deal with the problem I am facing -- merging several separate yet similar modules into one single merged module. How do I approach this, what are some things that could help, etc. That's what I'm looking for.
Hi all, Hopefully this will be a very easy question for one of you! Basically, I've created a little invoice script, and I need some help with the invoice data (i.e the item info, qty and the price). My question is how do i deal with the data from multiple rows containing 3 text fields each (item, qty and price). I've been playing with a foreach loop, which I can make echo info in the item field for each row. How do I incorporate the other fields (the qty and price)? Can I build an array to hold it all? Thanks for any help! Jim Hi All, Im new to this forum but think its going to be a regular location for me for quite a while. Im very very new to php and the guy that was doing code for me is not responding to emails, so i thought id have a go myself...lol at the moment im going through the trial and error phase while learning. I have edited some of the code he has put on the site to create a new look. the original page: http://www.ridersguide.co.uk/county_accommodation.php?county=4; the one im trying:http://www.ridersguide.co.uk/county_accommodation2.php?county=4; The new bit is to add a preview of the text for the page. echo $row[ad_text]; the code above brings up all the text but i only want to show the first 4 or 5 lines. Is this possible in php? Any help appreciated Neil Thanks ahead of time, I have been working this all week end but get lost.... a. I want to insert all the lines from file1.txt into file2.txt . b. I want the all lines in file1.txt to be inserted in file2.txt starting at "<image>" tag label in file2.txt. c. I would like to overwrite all lines that start with the "<image>" tag in file2.txt with the insert (text in file1.txt contains <image> tag also). file2.txt has lines above and below the insert point <image>. The insert text (file1.txt) could be as many as twenty lines (records) all/each beginning with the<image>tag. Here is what I have done so far. <? $key = '<image>'; //a text tag in $file1 and $file2 //copy file $file = "file1.txt"; $file2= 'file2.txt"; $newfile = "filetemp.txt"; copy($file, $newfile) or exit("could not copy $file"); //load file array $fc = fopen ($file, "r"); while (!feof ($fc)) { $buffer = fgets($fc, 4096); $lines[] = $buffer; } fclose ($fc); //open same file and use "w" to clear file ,not sure this is needed $f=fopen($newfile,"w") or die("$file did not open"); /* uncomment to debug print_r($lines); print "<br>\n"; */ //loop through array 'foreach foreach($lines as $line) { fwrite($f,$line); //rewrite $line in file if (strstr($line,$key)){ //find $key in each line fwrite($f,$newline."\n"); } //rewrite $line in file } fclose($f); copy($newfile, $file2) or exit("could not copy $newfile"); ?> Again thanks ahead of time, I just keep losing the flow, old I guess.
