PHP - Php Configuration Functions

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!

 

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've been googling for a while now for an example of how to read, edit and write a configuration file.

This part was easy to find...
<?php
$icon_settings = parse_ini_file("test.desktop");
print_r($icon_settings);
?>

...the above code works great, but how do I edit and write back a configuration file like this...
Code: [Select]
#!/usr/bin/env xdg-open

[Desktop Entry]
Version=1.0
Name=Firefox Web Browser
Comment=Browse the World Wide Web
GenericName=Web Browser
Exec=firefox %u
Terminal=false
X-MultipleArgs=false
Type=Application
Icon=firefox
# ... and so on
back to the drive?

Thanks.

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.

I have a script I am putting together that simulate a cricket game. The only issue is, that there are a huge number of functions because there doesn't seem to be any other way to do this properly. As well as this, there a while() loop and all this seems to be leading to the page reaching a max 30 second timeout when generating the result.

My code is attached below, it is quite messy at the moment because i've just be working on it, but I was wondering if anyone has any solutions of how I can speed this up or change to prevent a timeout:

I teaching myself php, but I am coming from java and other compiled languages, so the process has been a little bumpy. I am trying to do something like this:

Code: [Select]
class my_class
{

  function one ()
  {
     $two = two ();

     $three = three ();

     $five = $two + $three;

     return $five;
  }

  function two ()
  {
     $two = 2;

    return $two;
  }
 
  function three ()
  {
     $three = 3;

     return $three;
  }
}


Unfortunately, I keep getting an error message saying that my call to two () is an undefined function. I am gathering from this that the scope of one () is not aware of the existence of two (). Is there a way to get around this so I can call two () and three () from one ()?

When in OOP I have been watching tutorials and some have functions just written like Code: [Select]
class user
{
 public $user;

 public function __construct($u)
 {
   $this->user = $u;
 }

}
do I need to type public before the function or is it better practice to just put

Code: [Select]
class user
{
 public $user;

 function __construct($u)
 {
   $this->user = $u;
 }

}


Thanks!

I have a function to get some data from the database. However it always comes back with:

Code: [Select]
Notice: Undefined variable: db in C:\wamp\www\ASF A Simple Forum\functions\functions.php on line 233

}

I have a function for mysqli_real_escape_string above this function and it works with no errors.

Have i done something wrong? as you can see i am including the file which holds the connection but it doesnt seem to use it. every other file that uses the connection works fine.

i am wondering what the '@' is used for when used in front of a function like


Function(@$VAR);


What is the benefit of the @?

Hey guys.
Can anyone tell me what this means?
function foo 
{
}


It is basic php but I don't get it. Should it be called for execution, or does it work automatically, or both?
The php manual at w3schools and php.net are too tough for me. That's why I posted here.

Thanks!

Hi,

I've got 3 different upload forms in one form.  I'm making a function so it just one piece of code.

I'm having a bit of a problem changing some of the code so it works for all 3.

Here is the function




function loadImages ($action, $position)
{
 $link = mysql_connect("","","");
if (!$link)
{
die('Error: could not connect: ' . mysql_error());
}

$db_select = mysql_select_db("",$link);
if (!$db_select)
{
die ("Error: database selection failed: " . mysql_error());
}
$page = ($_POST["pageName"]);
if ((($_FILES["bfile"]["type"] == "image/gif")
|| ($_FILES["bfile"]["type"] == "image/jpeg")
|| ($_FILES["bfile"]["type"] == "image/pjpeg"))
&& ($_FILES["bfile"]["size"] < 9000000))
{
if ($_FILES["bfile"]["error"] > 0)
{
echo "Return Code: " . $_FILES["bfile"]["error"] . "<br />";
}
else
{
 $success = '<p style="font-weight: bold; color: #C00">Upload successful<br />';
// move uploaded temporary file to final destination
move_uploaded_file($_FILES["bfile"]["tmp_name"],
"uploads/" . $_FILES["bfile"]["name"]);

// update database with new filename
 $filename = $_FILES["bfile"]["name"];
 $sql = "UPDATE images 
 SET filename= '$filename'
 where page = '$page'
 and position = '$position'";

if (!mysql_query($sql,$link))
{
die('Error: ' . mysql_error());
}

}
}
else
{
 $fail = '<p style="font-weight: bold; color: #C00">Invalid file';
}
mysql_close($link);
}


Now the $action is the bit that will determine whether it's updateTop updateMiddle or updateBottom.  $position finds out if it's top middle or bottom


if (isset($_POST['updateTop'])) 
    {
loadImages ($_POST['updateTop'], "top");
}


Here is a sample of the html, it's in a switch

case "Products":
                              echo "<p>Image Top</p>
                                    <input type=\"file\" name=\"file\" id=\"file\" />  <input type=\"submit\" name=\"updateTop\" value=\"Update $page Top\" />
                                    <p>Image Middle</p>
                                    <input type=\"file\" name=\"mfile\" id=\"mfile\" />  <input type=\"submit\" name=\"updateMiddle\" value=\"Update $page Middle\" />
                                    <p>Image Bottom</p>
                                    <input type=\"file\" name=\"bfile\" id=\"bfile\" />  <input type=\"submit\" name=\"updateBottom\" value=\"Update $page Bottom\" />
                                    ";
                              break;


What I need to do is get $_FILES["bfile" into a variable to see whether it's "bfile" "mfile" or "file" but not sure how to write it.

Thanks for the help.

Hi, I could use a little guidance here. 1) is a function with
values to be sent to 2).

1) <!-- use ajax - OnCalc function to send data to your database. -->
function OnCalc(value1,op,value2,total)
  {

2) php file using above function values
<?php
  header( "refresh:5;url='http://localhost/hom...lcprint.php'");
  echo 'You\'ll be redirected in about 5 secs. If not, click <a

href="http://localhost/hom...hp">here</a>.';

echo '<script type="text/javascript">'
   , 'OnCalc();'
   , '</script>';
No error but code not working?
