PHP - Change Value In A Configuration File

Every now and then, I experience some strange behavior and eventually trace it back to parse_ini_file's scanner_mode being applicable to some parameter but not another, and am looking for alternatives.  Below are several of my thoughts.  How do you store configuration settings?  Do you use different approaches based on the application, and if so what criteria governs which you use?

Keep with a ini file with parse_ini_file.  Obviously, not working for me. An ini file but with a class dedicated to ensuring the data is appropriate.  Seems like too much duplicating content which will result in errors. YAML.  Don't think I want to. XML.  Not as readable. In a database.  Maybe, but might be harder to manage. Hardcode an array in PHP.  Probably not. JSON.  I like the idea, but feel comments are important in a config file, and am considering the following: Add extra valid JSON properties which contain comments.  Don't like the idea. Use JavaScript's JSON.stringify.  Too much mixing technologies. Add comments to the JSON and then strip them using a 3rd party parser such as https://json5.org/ or a little regex.  My main issue is inability to auto-format, but this seems viable. Any other ideas?

Thanks!

 

Hi Guys,

I'm a bit new to php coding, so dont really know what the best way to code this up.
I want to make a router configuration page, such as it shows the link status (ip/gatewatway etc) and also have input selections such as to turn on/off wifi / dhcp etc.
Ideally I would like the data stored and written to a text file as the php server is running on a linux arm embedded system. At present I have been able to read back from a text file the corresponding values for each of the status information (these are stored on a seperate line), but I'm having difficulty writing and reading the input selection boxes, such as when the dhcp is disabled I need it to write to a file that its been disabled and refresh the page to allow entry of the static ip box and then when the apply button is pressed the value is written to the file.

This may be out of my depth, hopefully someone could give me some pointers.
I feel that the text file might not be the best way of storing and recalling values but I don't know of another way.

Many Thanks
Tim

Hi ,   My site gives a blank page when i click on an article due to insufficient memory. I tried making changes to the php.ini file but the changes are not getting reflected.   Please advice if a server restart is needed for this, how do i go about it?   Thanks in advance

I have a configuration file, and I use parse_ini_file() to parse it into an array at the initial entry point of my script.   I would like the settings to be available to all downstream scripts/methods/functions. Note that my intent is not to change them outside of the configuration file, and ideally they will be readonly, however, if not, I suppose that is okay and I will just be sure not to modify them.   I've read about dependency injection, and while this mostly makes sense, it seems like a lot of script/troubleshooting for little if any value for this scenario.   I've read that global variables are bad (couples your objects to some "god" object, cannot unit test, difficult to troubleshoot, difficult to work with multiple developers, potential conflicts with other classes, namespace pollution), but maybe not for this case?   Another option is defining a bunch of constants to the appropriate values, but this seems redundant.   Or maybe some static class with all the values?   What would be the best way to make configuration settings available to all PHP scripts, functions, and methods?

Hi,

I don't know if this is even possible, but I need to copy configuration of existing server to my localhost (using XAMPP on windows). I only have full output of phpinfo() function from that server (I don't have access to php.ini), and I would like to change my localhost server to behave exactly like remote one. 

Is this even possible? 
Is there some more "automatic" solution, than just going through bunch on lines of code and trying to change them?
Furthermore, remote server has much longer configure command, as well as list of additional .ini files parsed... how to change these?

Hey Guys,
First Post! Yay 
I have a problemo, I feel really stupid about having to ask this question. But basically I can't get a new line when I echo output in a script I am writing for my website.
Here is the code:
echo $newsentry;
echo '_______
Read More..';

I tried '\n' I tried using " (double quotes) I have used ' (single quotes) I have positioned the Line Feed '\n' at the begining of an output, and at the end. Neither made any difference. I tried using carriage return '\r' too. Nothing.
I haven't coded in PHP for a while, well nothing basic (I know that sounds rediculas but it has been mostly Apps etc, Client Scripts blah blah blah, but I haven't had to echo with a new line for a few years. Probably the last website which I wrote with my friend. So I checked the PHP manual, and I am clearly missing something when I am reading it, I understood it to mean (which as you can see from my code, is what I am currently doing), that you could just somehow type:
echo "some string
and it carries on to the second line";
However as I first thought, this makes no difference.
Could this be a configuration on the Box that hosts this Site??
Sorry for sounding so stupid guys, I appreciate your help.

Hi

I need to change the name of a file being uploaded by a user. The reason i need this is because there is a strong possibility that duplicate filenames would be logged.

This is the code i have currently:

Code: [Select]
   $upload_path = 'cv/'; // The place the files will be uploaded to (currently a 'files' directory).

   $filename = $_FILES['userfile']['name']; // Get the name of the file (including file extension).
   $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename.

   // Check if we can upload to the specified path, if not DIE and inform the user.
   if(!is_writable($upload_path))
  die('You cannot upload to the specified directory, please CHMOD it to 777.');

   // Upload the file to your specified path.
   if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename));

This code works fine to upload the file in the current name.

I assume i need to seperate the filename from the file extension, and i can then assign a new variable to the filename. Easier said than done though as Ive tried many combinations of things.

Is there a simple way using this script? or will i need to start from scratch?

Cheers

I used the move_uploaded_file function to upload files to my server ,but the function changes the Arabic names of files because most of my files are Arabic named  how can I fix that ?

Ok so I have this script that I wrote and it works really good.  I wanted to display the number of records in a table and since the db only changes once per day I thought I would put the couner on the back end.  I have this script that changes the value of the text file every day.  But I would love it if it outputted with commas.   Now it reads: 1234070   Want it to read: 1,234,070   Any thoughs?

#!/usr/bin/php -q
<?php
$username=""; // READONLY USER USED HERE AND AUTH'D ON LOCALHOST ONLY
$password="";
$database="";
$dbhost="";

mysql_connect($dbhost,$username,$password);
@mysql_select_db($database) or die( "Unable to connect to database please try again!");

$counthd=mysql_query("SELECT count(*) as total from HD");
$hdtotal=mysql_fetch_assoc($counthd);
$dbcount = $hdtotal['total'];
echo "";

$myFile = "dbcounter.txt";
$fh = fopen($myFile, 'w');
fwrite($fh, "$dbcount");
fclose($fh);

?>

how to get the name of the file including a file from the included file,

This one has me mixed up a bit.. I am trying to record site activity information from a common.php file using a user object. But since the file is included into different php files based on different situations I need a dynamic way of finding the file name that is including it. I could be over complicating things but right now this seems like the best solution other wise I'll have to rewrite the code on every page i write. Is there a function for doing this? Or if someone gets what I'm trying to do if they could point me to the direction of some more information on it.

Thanks.

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')";
}
}
}
}
?>

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!

Hiya,

Firstly, I'm a complete novice, apologies! But I have got my upload.php working which is nice. I will post the code below.

However, I would now like to restrict the file size and file type to only word documents.

I currently have a restriction of 200KB but it's not working - no idea why as I've looked at other similar codes and they look the same.

Also, just to complicate things - can I stop files overwriting each other when uploaded? At the moment, if 2 people upload files with the same name one will overwrite the other.

Is this too many questions in 1?

Any help is very much appreciated!

Code below:

Code: [Select]
<form enctype="multipart/form-data" action="careers.php" method="POST">
        Please choose a file: <input name="uploaded" type="file" /><br />
<input type="submit" value="Upload" />
</form>

<?php 
 $target = "upload/"; 
 $target = $target . basename( $_FILES['uploaded']['name']) ; 
 $ok=1; 
 
 //This is our size condition 
 if ($uploaded_size > 200) 
 { 
 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 "Your file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded."; 
 } 
 else 
 { 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 } 
 ?>
