I have attached the text file, will you guys please look at it and tell me how to replace that square looking character into new line in text file.

Hi,

Have a text file that is being read. I want to print the contents however I want each line of the text file to appear on a new line in the browser.

So far
$str = file_get_contents('records.txt');
$lines = explode("\n", $str);
echo $lines[0];

Help appreciated

This is a section of my code that goes and gets videos from any video site. What I’m having issues with is having it post a random title, that are all in a text file called titles.txt. What I’m wanting to accomplish is have my script go pull the video embed code, the duration, the tags, etc. Which all works fine until I get to the title part where it pulls locally from the server from the text file. I'm not an advance programmer so not sure if I am even approaching this correct way. Here is the code I have that is responsible for putting the title in. I appreciate your help.

$video = array(
‘user_id’ => $this->user_id,
‘status’ => $this->status,
‘site’ => ‘my site’,
‘id’ => ‘’,
‘embeddable’ => true,
‘url’ => ‘’,
‘titles’ => ‘’,
‘title’ => ‘’,
‘description’ => ‘’,
‘tags’ => ‘’,
‘category’ => ‘’,
‘thumbs’ => array(),
‘duration’ => 0,
‘embed’ => ‘’
);

function random_title ()
{
$titles = file (“titles.txt”, FILE_IGNORE_NEW_LINES);
$num = rand (0, intval (count ($titles) / 3)) * 3;
return ucwords($titles[$num]);
}

//Title
if(preg_match(’/title="(.*?)"/’, $match, $matches_title)) {
$video[‘title’] = random_title(). ’ - My site name’;
} else {
$this->errors[] = ‘Failed to get video title for ‘.$video[‘url’].’!’;
if (!$this->debug) continue;
else $debug_e[] = ‘TITLE’;
}

 

Here's what I'm trying to do, and I am having trouble getting started with this.  It's a very simple process, but I didn't want to spend the next 6 hours in frustration, so some help getting started would be great.

Here's the purpose of the script:
1. Allow user to add a text file to a form.
2. Take the text file, add HTML code to the beginning and end of each paragraph (a single line of text, usually paragraphs would be separated by a line return)
3. Send the user an email with the HTML file attached and thank them or whatever.
4. Allow the system to throttle itself (one-at-a-time) so that many people using the site won't bog it down.  These files will probably be anywhere from 100 KB to 1,000 KB in size, usually hitting in the 300-500KB range.

Here's what I can do very easily:
1. Allow user to add a text file - very simple and straightforward.
2. Take the text file, add HTML... - this is what I need a little help figuring out.  Each paragraph needs to have <p> at the beginning and </p> at the end, and the script will also search for keywords on certain lines (section headers) and add a <align="center"> tag to that, and so forth.  I can handle the formatting rules, but making sure the loop runs correctly could be a problem.
3. Send the user an email... - very easy, I can do that myself.
4. Allow the system to throttle itself... - this could be tricky.  I was thinking a database with a TINYINT field, 0 for not processed yet, 1 for processing, 2 for processed.  Cron job checks the next one on the list to see if it needs to send it to the processor, if the file is already being processed, or can be sent to a different database (completed entries) and removed from the current queue.  The cron job would also be responsible for triggering the "Your file is converted!" email and the attachment.

Any/all help would be greatly appreciated on this.  I am going to work on the parts that I can do myself, and I'll be checking back for the discussion - in between Mountain Dew runs.

I'm ok with PHP but probably not half as good as some of you guys on here.

I am basically trying to find a way to grab a line from a huge and I mean huge text file.... its basically a list of keywords I want to call by line number but without preferably going through them all before I get to that line.....otherwise couldmcrash my server obviously.

At the moment im using this

Code: [Select]
$lines = file('http://www.mysite.com/keywords.txt');

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
echo "$line_num";
}
This works but im sure theres gotta be a better way of doing to save on usuage because this is putting the whole file into the memory and if I can simply say to php give me line number 97, would umm RULE....

Hope you guys can come up with a solution as your much smarter than me ty

I have a PHP file that is executed via batch file very frequently for live updating. This is a sort of "sync" file for reading/writing to a MySQL database. I am able to get it functioning absolutely fine when executed manually via a web browser (and my echo debug lines output the expected information), yet when I run the same PHP file via the command line, it seems to just not be capable of opening any file for reading, so the equivalent variables that are correct when executed on a web browser are blank when echoed through the command line.

Is there a different way of handling reading of files when running a php script via the command line, or should it function exactly the same as when run via a browser?

For instance:

$k = "0";
$line = file("examplefile.log")[$k];
echo $line;

I embed videos on my site. I submit the embed codes to my database using a form. The codes look like this:

<iframe width="560" height="315" src="//www.youtube.com/embed/xDIgbjDGsOM?rel=0" frameborder="0" allowfullscreen></iframe>

Before I submit each code, I have to change its width and height, and I have to add this:

&showinfo=0

after this:

?rel=0

Is there a function that will allow me to do all of that simultaneously?   I know about str_ireplace(). It will let me replace ?rel=0 with ?rel=0&showinfo=0, but I don't know how to simultaneously make the other changes.   It's not helping that the embed code includes quotation marks.

In this multi file upload form, choose three images, click submit and preview the images on the preview page. If the user wishes to delete or replace an image, click edit and the form will go back to the previous page. Select the replace radio button for example on one of the three images and select a new image from the file input prompt and click submit. The form will go to the preview page again to display the images. During this process the image names are being input into a table and the images are being moved to a directory.

The table is

  `id`  AUTO_INCREMENT,
  `image0`
  `image1`
  `image2`
  `status`

So input name='image[image0]' can be directed to table `image0` and so on.

The code for keep and delete work fine, but how do I replace an image?
I have two foreach blocks. The first one deletes the image file from the directory and deletes the image name from the table, but the second foreach dose not move the new image file into the directory.
Thanks.

<input type='radio' name='image[image0]' value='keep' checked='checked'/>
<input type='radio' name='image[image0]' value='delete' />
<input type='radio' name='image[image0]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image1]' value='keep' checked='checked'/>
<input type='radio' name='image[image1]' value='delete' />
<input type='radio' name='image[image1]' value='replace' />
<input type="file" name="image[]" />

<input type='radio' name='image[image2]' value='keep' checked='checked'/>
<input type='radio' name='image[image2]' value='delete' />
<input type='radio' name='image[image2]' value='replace' />
<input type="file" name="image[]" />

<?php
if (isset($_POST['status'])) {

$status = $_POST['status'];
$confirm_code = $status;

#--------------------------- replace --------------------------------------------

if (isset($_POST['submitted']) &&
($image = $_POST['image'])) {

foreach($image as $imageKey => $imageValue) {
if ($imageValue == 'replace') {
$query = "SELECT $imageKey FROM table WHERE status = '$status' ";
if($result = $db->query( $query )){
$row = $result->fetch_array();
}

unlink( UPLOAD_DIR.$row[0] );

$query = "UPDATE table SET $imageKey = '' WHERE status = '$status' ";
}
}

foreach($image as $imageKey => $imageValue) {
if ($imageValue == 'replace') {

$filenm = $_FILES['image']['name']; 
$file = $_FILES['image']['tmp_name'];

move_uploaded_file($file, UPLOAD_DIR . $filenm);
$filename[] = $filenm; 

$query = "INSERT INTO table VALUES ('','$filename[0]','$filename[1]','$filename[2]','$confirm_code')";
}
}
}
}
?>

Is there a simple way getting PHP to open a single file and write to a specific line?

Like:
fwrite (line = 102) {"bla bla bla"};
fclose;

Hey everyone, I'm pretty new to this, not my full time job, but just something I thought I'd give a shot...

I have a database, in postgres, in which I make my query and I go fetch all the info I need.
What I need to do next is the tricky part for me.

For each line of results received, I have to output to a text file (.txt) but I have to respect a format that was given to me from the person requesting the info.

Example:
Character 1 must be G or N.
Character 2 to to 11 will be a result from my database search, which is a 10 digit string.
Character 12 to 14 must be spaces.

Another rule is:
start at character 78: input a value from my database search but it must not exceed 20 characters and if it is less then 20 character, fill the remaining with spaces.


If anyways has a code I can copy and work off of I would really appreciate it....thanks!

Hey guys, total newb when it comes to php. any help here would be much apreciated,

what i am trying to achieve is to allow a person to upload a jpg image that he wants displayed on a dynamic flash site, but seeing as the flash is looking for xx.jpg, is it possible that any jpg file he uploads , say its called golf.jpg, is automatically uploaded/renamed to xx.jpg ? so i dont have to get him to rename the files before uploading.

i attempted to understand a short tutorial on doing this but failed, here is what code i used. ( i added that rename line, looking at it now sorta seems like a really lame attempt lol )

Code: [Select]
<?php 
 $target = "upload/"; 
 $target = $target . basename( $_FILES['uploaded']['name']) ; 
 $ok=1; 
 
rename ("*.jpg", "xx.jpg");

 //This is our size condition 
 if ($uploaded_size > 350000) 
 { 
 echo "Your file is too large.<br>"; 
 $ok=0; 
 } 
 
 //This is our limit file type condition 
 if ($uploaded_type =="text/php") 
 { 
 echo "No PHP files<br>"; 
 $ok=0; 
 } 
 
 //Here we check that $ok was not set to 0 by an error 
 if ($ok==0) 
 { 
 Echo "Sorry your file was not uploaded"; 
 } 
 
 //If everything is ok we try to upload it 
 else 
 { 
 if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) 
 { 
 echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded"; 
 } 
 else 
 { 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 } 
 ?>
 
<body>
<form enctype="multipart/form-data" action="upload.php" method="POST">
 Please choose a file: <input name="uploaded" type="file" /><br />
 <input type="submit" value="Upload" />
 </form>

cheers

I need to add these lines to my .htaccess file via PHP

Code: [Select]
RewriteCond %{REQUEST_URI} checkout
RewriteRule ^(.*)$ https://myurl.com/checkout/$1 [R,L]
RIGHT after this line:
Code: [Select]
RewriteBase /
AND before this line:
Code: [Select]
RewriteCond %{REQUEST_FILENAME} !-f
This is how the current file looks w/o the new line addition:

Code: [Select]
RewriteEngine On

RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php [L,QSA]
It needs to look like this when the new lines are added(extra line breaks not necessary):

Code: [Select]
RewriteBase /

RewriteCond %{REQUEST_URI} checkout
RewriteRule ^(.*)$ https://myurl.com/checkout/$1 [R,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)$ index.php [L,QSA]
The line numbers may not match up, so I cannot use the line number.

when the blow code is ran it produces this warning error

Warning: filemtime() [function.filemtime]: stat failed for 048_Baby_Colors.png in /home/public_html/.com/kill.php on line 23



The code deletes all the files in the directory no matter how many hours or seconds ago they was last modified. could someone help me figure out why?

<?php

$dir = '/home/br/public_html/l.com/dfile';

if ($handle = opendir($dir)) {


    while (false !== ($file = readdir($handle))) {

        if ($file[0] == '.' || is_dir("$dir/$file")) {


            continue;

        }

        if ((time() - filemtime($file)) > ($days * 604800)) {

            unlink("$dir/$file");

        }

    }

    closedir($handle);

}

?>
