PHP - Make Brief To Contents
I used this code
$limit = 120; if (strlen($summary) > $limit) $summary = substr($summary, 0, strrpos(substr($summary, 0, $limit), ' . . .')); This code ok in English Language it counts letters fine but it is not work fine if I insert Arabic text. It counts Arabic encoding characters. Similar TutorialsOkay so my news script is set to view only 10 pieces of news. But I want it so that it starts a new page once I have more than 10 pieces of news. Code: [Select] <?php require("functions.php"); include("dbconnect.php"); session_start(); head1(); body1(); new_temp(); sotw(); navbar(); $start = 0; $display = 10; $query = "SELECT * FROM news ORDER BY id DESC LIMIT $start, $display"; $result = mysql_query( $query ); if ($result) { while( $row = @mysql_fetch_array( $result, MYSQL_ASSOC ) ) { news_box( $row['news'], $row['title'], $row['user'], $row['date'], $row['id'] ); } mysql_free_result($result); } else { news_box( 'Could not retrieve news entries!', 'Error', 'Error', 'Error'); } footer(); mysql_close($link); ?> I tried a few things but they failed....miserably. Hi all
So I'm back to being a php newbie after not touching the stuff for years....and straight back to being pretty sure I'm just incredibly stupid.
I want to grab the contents of a url onto a string so that I can search the string and use the contents. I think this should work:
<?php
$homepage = file_get_contents('http://www.example.com/');
echo "Homepage = " . $homepage;
?>
But it doesn't. What am I doing wrong, or could there be an issue with my server that means it's not able to perform this maybe? (It's working fine for everything so far)
Or is there another way of achieving this?
Thanks!!
I want to parse some tiny lines from a webpage. I have few questions: 1. What is faster and better: cURL or file_get_contents? 2. Is it better to run preg_match commands form every line I want OR first get a shorter part (e.g. between <head> tag) then running preg_match for the lines? 3. Actually, I need to load the whole page before parsing. Is there a way to stop loading the whole page. For example, when I want something between <head> tag; stop loading <body>? Thank you in advance! I have this script below that makes an XML which displays the contents of a directory which contains image files. After running the .php, the XML output looks like this: Code: [Select] <gallery> <content src="./uploaded/images/Desert.jpg"/> <content src="./uploaded/images/Penguins.jpg"/> <content src="./uploaded/images/tux.png"/> <content src="./uploaded/images/Jellyfish.jpg"/> <content src="./uploaded/images/Chrysanthemum.jpg"/> <content src="./uploaded/images/Tulips.jpg"/> <content src="./uploaded/images/Koala.jpg"/> </gallery> I would like the output to be like: Code: [Select] <gallery> <photos> <photo> <content src="./uploaded/images/Desert.jpg"/> </photo> <photo> <content src="./uploaded/images/Penguins.jpg"/> </photo> <photo> <content src="./uploaded/images/tux.png"/> </photo> <photo> <content src="./uploaded/images/Jellyfish.jpg"/> </photo> <photo> <content src="./uploaded/images/Chrysanthemum.jpg"/> </photo> <photo> <content src="./uploaded/images/Tulips.jpg"/> </photo> <photo> <content src="./uploaded/images/Koala.jpg"/> </photo> </photos> </gallery> Here is the script: Code: [Select] <?php $path_to_image_dir = "./uploaded/images"; // path to your image directory $xml_string = <<<XML <?xml version="1.0" encoding="UTF-8"?> <gallery> </gallery> XML; $xml_generator = new SimpleXMLElement($xml_string); if ( $handle = opendir( $path_to_image_dir ) ) { while (false !== ($file = readdir($handle))) { if ( is_file($path_to_image_dir.'/'.$file) ) { $image = $xml_generator->addChild('content'); $image->addattribute('src', $path_to_image_dir.'/'.$file); } } closedir($handle); } header("Content-Type: text/xml"); echo $xml_generator->asXML(); ?> Hello friends, if i have the following $path = "http://*site*.com"; why can't i write the following $ORGtext= file_get_contents('$path'); it works only if i write $ORGtext= file_get_contents('http://*site*.com'); but i want to put $path instead of the url at file_get_contents is it possible and if yes then how ? thank you What is the proper way to output the contents of a class? (We will assume that Getters and Setters are evil...) Let's say I have the following class... class FormHandler2 { // Define Variables. private $myFormArray; // Constructor. public function __construct($param){ $this->myFormArray = $param; } } ...and I want to be able to output its contents either via a variable dump OR by printing something to the screen. How would I do that? TomTees Hi guys. This is my first post here, so excuse me if i am posting this in the wrong forums. I am making a website, and having a huge problem. The script is used for orders of different services. And i am using sessions to store the information through serveral pages. But my problem is that on my final page, where the script sends an email with i can not get it to view the contents of one session. I am using the same session on a different page and it works like a charm. When i try debugging the session it won't print the contents, so i am guessing something is very wrong? My code of the page is bellow, let me know if you need anything else: http://pastebin.com/YHh3bGWS Please help me eg http://www.xxxxxxx.com/index.php?action=viewarti&artid=5 How can I write the content of this link into file. how do i make this part of the script delete the folder and contents. Code: [Select] <?php $path = "../../gallery/gallery_files/gallery/"; if(isset($_POST['file']) && is_array($_POST['file'])) { foreach($_POST['file'] as $file) { rmdir($path. "/" . $file) or die("Failed to delete file"); } } ?> This is source of a page: http://vn-ace.com/forum/test.txt I want to get contents betweent <blockquote class="postcontent restore">() and </blockquote>() but i dont know how to do ? How can i do ? Please help me. I am newbie. Thanks I have a purchase order displaying on a site that the user can edit quantities for. I want them to be able to hit submit and it takes that form and submits it to some code that auto creates a PDF with it. The PDF part is easy, I use DOMPDF to create that and it works fine, I just can't seem to get the values passed through. I can easily pass the values of just the input boxes through the $_POST but I don't want to have to recreate the PDF setup after the post. I'd rather just use some Javascript or something to grab the innerHTML of a <div> element and somehow make it available after the form is submitted so the PHP code can use it to send to DOMPDF. The form submits to itself and I have a piece of code at the top of the page which will create the PDF, I just need the <div> contents and I'm done. How do I get it? I could set it into a hidden variable but the reason I'm not doing that is because for some reason when I assign the big table which contains the whole purchase order into the hidden variable and then try to print it, it comes out all messed up. I don't know why and I'd rather just find another way than attempt to figure that out. How does a web server, with a database connect to the emails it receives? How does the web server get the contents of the emails it receives so I can parse it? Thanks Hey there, I have an image gallery running on my website right now and I want to give the site admins access to add/delete the images from the different gallery directories. But to be honest I'm totally lost on how to do it lol I know my way around PHP but I've never had to code something to pull up the dir contents with an option to delete the files. I've found scandir which will get the contents of a dir and unlink which deletes a file but I have no clue how to get them to work together, anyone got any ideas or a different function if I'm looking in the wrong direction with those functions. Any help would be much appreciated. Thank you! Hi This is something used in CPUs Logical shift right I have a string $bin = "10011101"; // result should be "01001110" the function is function LogicalShiftRight($bin) { for($x = 7; $x == 0; $x--) { echo $x; $bin[$x+1] = $bin[$x]; } $bin[0] = 0; return $bin; } cant get the loop to work backwords. This is an 8 bit shift right putting a zero at the highest bit. I am trying to use the following code to include a directories contents and was wondering what im doing wrong, because its not working? Code: [Select] if ($handle = opendir('../configs')) { while (false !== ($FILEZ = readdir($handle))) { include "$FILEZ"; } closedir($handle); } Hello there, Using PHP, what's the best way of replacing the contents between different HTML 5 element tags on the fly? Some of the elements I'm looking to change can be found below. I have looked into the possibility of using Regular Expressions, but have found lots of material on the internet that try to prevent you from using such a method for parsing HTML due to speed and other HTML code related issues. Any help, example code, and ideas on this is greatly appreciated. Code: [Select] <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>Some Title</title> </head> <body> <div>Replace contents of div tag.</div> <p class="someClass">Replace contents of p tag.</p> <table> <tr> <th>Static Table Heading 1</th> <th>Static Table Heading 2</th> <th>Static Table Heading 3</th> </tr> <tr> <td>Replace Table Data 1 Contents</td> <td>Replace Table Data 2 Contents</td> <td>Replace Table Data 3 Contents</td> </tr> <tr> <td>Replace Table Data 4 Contents</td> <td>Replace Table Data 5 Contents</td> <td>Replace Table Data 6 Contents</td> </tr> </table> </body> </html> Hi guys! Could you give me advice about this issue: index.php Code: [Select] <?php $page = $_GET['page']; if ($page == NULL) { $page = "main"; } ?> <div>Header</div> <div> <?php require("view/$page.php");?> </div> <div>Footer</div> main.php Code: [Select] <?php require "func.php"; ?> <form method="post" action="view/add.php"> <input type="text" name="from" value=""><br /> <input type="submit" value="Add"> </form> add.php Code: [Select] <?php require "../func.php"; $from = $_POST['from']; $a = add($from); echo $a; ?> func.php Code: [Select] <?php function add($a) { $c = $a+100; return $c; } ?>I need output result (echo $a) in new windows (target= _blank) and output must be same like with main.php. In other words content of add.php output in index.php This code is just simplified of real code. Thank you in advice Hey, I need a bit of help replacing some variables in a string. I know its done with preg_replace. Here is the string: Code: [Select] Header 1 <|header 2|> header 3 <b>header 4</b> I would like to get ONLY <|header 2|> from the above string. But "header 2" is variable so please its useless if the preg_replace isn't flexible to find whatever word is in there regardless. Thanks you. Hello, I have a simply query that will if a simple two different things: Code: [Select] $cssyn = mysql_query("SELECT `12` FROM `12345` WHERE `abc` = '$_SESSION[number]'"); $cssy = mysql_fetch_row($cssyn); if($cssy[0] == "YES") { echo "Yes"; } else { echo "No"; } The YES or NO result is stipulated earlier on so thats not the problem. But basically before I added the if statement simply would have echoed a table with all the rows etc from another query. However I would like to give the user a choice between echoeing the results into one table or a neater two. I have separated the code for the table and the queries into two separate files but say if I use: file_get_contents then it just prints the HTML and doesnt actually populate it will the queried parts. Nor if I use something like include() then it wont echo anything, which it wouldnt unless called so what I am asking is: Is there a way to get EVERYTHING from the file if the answer is YES or the other file if NO. I have 2 pages...1 one that has something like 500 checkboxes that list all of the active users in a database. When any number of checkboxes are selected it passes the variables from the checkboxes to the next page, asking for confirmation.
Right now I have the 2nd page displaying numbers for the people, but doesn't display the correct entries.
The code is below, hopefully it helps:
if(isset($_POST['Update'])) //if the update button was pressed
{
if (isset($_POST['Player_number'])) //checks to see if any checkboxes are selected
{
//$Player_number = IMPLODE(',',$_POST['Player_number']); //putting the comma in between the array items
echo $Player_number;
?>
<input type="hidden" name="<?PHP $Player_number; ?>" value="<?PHP $Player_number; ?>">
$Player_number = IMPLODE(',',$_POST['Player_number']); //putting the comma in between the array items
$result = mysql_query("SELECT * FROM `players` WHERE `Player_number` = '$Player_number' ORDER BY Player_Last_Name") or die(mysql_error());
while ($row = mysql_fetch_array($result))
//while ($row = mysql_fetch_assoc($result))
{
// here is your data
echo "FName: ".$row['Player_First_Name'];
echo "lName: ".$row['Player_Last_Name'];
echo "email: ".$row['player_email'];
}
foreach($_POST['Player_number'] as $row)
{
$result = mysql_query("SELECT `Player_First_Name`,`Player_Last_Name`,`player_email`, `Player_number` FROM `players` WHERE `Player_number` = '$Player_number' ORDER BY Player_Last_Name") or die(mysql_error());
$Player_number = IMPLODE(',',$_POST['Player_number']); //putting the comma in between the array items
while($rows=mysql_fetch_array($result))
{
echo "Player Number: ".$Player_number;
//echo "pNumber: ".$row;
//echo $rows['Player_First_Name'];
?>
<tr bgcolor='<?PHP echo $bkcolor; ?>'>
<td width = '20%' height="20"><div align="center"><input type="hidden" name="Player_number[]" value="<?php echo $row; ?>"></div></td>
<td width= '20%' headers="20"><div align="center"><?php echo $rows['Player_First_Name']; ?></div></td>
<td width= '20%' headers="20"><div align="center"><?php echo $rows['Player_Last_Name']; ?></div></td>
<td width= '20%' headers="20"><div align="center"><?php echo $rows['player_email']; ?></div></td>
<?PHP
}//close of the while loop
}//close of the foreach loop
}//close of if (isset($_POST['Player_number']))
} //close of (isset($_POST['Update']
