Editing arrays

[herghost]

Hi everyone

 

I am using this code which is an example from a website

 

<?php
$file_handle = fopen("myfile", "rb");

while (!feof($file_handle) ) {

$line_of_text = fgets($file_handle);
$parts = explode('=', $line_of_text);

print $parts[0] . $parts[1]. "<BR>";
}

fclose($file_handle);

?>

 

Which does what it is meant to, however what I am trying to do is put all the input into a form, so values can be changed.

 

How do I separate each part? Eg the 1st line of the files reads isactive = true, how would I grab this so I can put it back to the file later as isactive = false? Not all the options are true/false, most are just strings or ints.

 

Thanks

[Andy-H]

Isn't that what you've just posted code to do?

 

 

If you mean how do you reference it:

<?php
$file_handle = fopen("myfile", "rb");
$vars = array();
while (!feof($file_handle) ) {

$line_of_text = fgets($file_handle);
$parts = explode('=', $line_of_text);
// either
$$parts[0] = $parts[1]; // $isactive = true;
// or
$vars[$parts[0]] = $parts[1]; // $vars['isactive'] = true; // this is the method I'd go for as some of your keys may have invalid variable names.
}

fclose($file_handle);

?>

Hi Andy

 

Thanks for your reply

 

If I run your code (removing the extra $ sign) I get a host of errors:

 

Undefined offset: 1 in C:\wamp\www\bm\text.php on line 42 = $parts[0] = $parts[1];

Undefined offset: 1 in C:\wamp\www\bm\text.php on line 43 = $vars[$parts[0]] = $parts[1];

 

I have also noticed that the 1st couple of lines are commented with # so I have removed these lines wondering if this was causing the error, but still get them:

 

$file_handle = fopen("saves/server.properties", "rb");
while (!feof($file_handle) ) 
{
$line_of_text = fgets($file_handle);
if( !preg_match('/^#.*?\n/',$line_of_text) )
echo $line_of_text . "<br>";

$parts = explode('=', $line_of_text);
$parts[0] = $parts[1];
$vars[$parts[0]] = $parts[1];

}

<?php
$file_handle = fopen("myfile", "rb");
$vars = array();
while (!feof($file_handle) ) {

$line_of_text = fgets($file_handle);
$parts = explode('=', $line_of_text);
echo '<pre> ' . print_r($parts, 1);
}

fclose($file_handle);

?>

Run that and post back the reply, I'm going out soon so can only help if you're quick.

 

 

The extra $ was intentional - PHP variable variables

[herghost]

Array
(
    [0] => #Sat Jan 07 07:04:01 UTC 2012

)
Array
(
    [0] => isactive
    [1] => true

)
Array
(
    [0] => level-name
    [1] => world

)
Array
(
    [0] => enable-query
    [1] => false

)
Array
(
    [0] => allow-flight
    [1] => false

)
Array
(
    [0] => server-port
    [1] => 25565

)

Thanks Andy!

The problem is, i cant seem to get the selected function working properly, all selects default to the last possible answer (last <select> option)

true !== "true"

[Andy-H]

<?php
$file_handle = fopen("myfile", "rb");
$vars = array();
while (!feof($file_handle) )
{
   $line_of_text = fgets($file_handle);
   $parts = explode('=', $line_of_text);

}
fclose($file_handle);

if ( $vars['allow-nether'] ) echo 'selected="selected"';
if ( !$vars['allow-nether'] ) echo 'selected="selected"';?>

[herghost]

Still not working Im afraid

 

//if date not required
   if ( !isset($parts[1]) )
   {
      continue;
   }
   $vars[$parts[0]] = str_replace('false', '', $parts[1]);


}
fclose($file_handle);


<option  <?php if ( $vars['allow-nether'] ) echo 'selected="selected"'; ?>  value="true"  >True</option>
                    <option <?php if ( !$vars['allow-nether'] ) echo 'selected="selected"';?> value="false" >False</option>

[Andy-H]

My bad. lol

[herghost]

I have noticed that if I do something like

 

<?php
$test = $vars['allow-nether'];
?>

 

Then when I come to call $test, dreamweaver is automatically opening a [ like it expects a array?

[Andy-H]

Run

echo '<pre>' . print_r($vars, 1);

 

 

after your while loop

Hi again Andy

 

Thanks for all your help on this, I fail to understand why its not doing what its meant to

 

I have run this with the original code and the updated code, so here goes:

 

$vars[$parts[0]] = $parts[1];
Array
(
    [allow-nether] => true

    [level-name] => This Blows!

    [enable-query] => true

    [allow-flight] => false

    [server-port] => 25565

    [enable-rcon] => false

    [level-seed] => 

    [server-ip] => 

    [white-list] => false

    [spawn-animals] => true

    [online-mode] => true

    [pvp] => true

    [difficulty] => 1

    [server-name] => Unknown Server

    [gamemode] => 0

    [max-players] => 20

    [spawn-monsters] => true

    [view-distance] => 10

    [motd] => A Minecraft Server

)

 

$vars[$parts[0]] = str_replace('false', '', $parts[1]);

Array
(
    [allow-nether] => true

    [level-name] => This Blows!

    [enable-query] => true

    [allow-flight] => 

    [server-port] => 25565

    [enable-rcon] => 

    [level-seed] => 

    [server-ip] => 

    [white-list] => 

    [spawn-animals] => true

    [online-mode] => true

    [pvp] => true

    [difficulty] => 1

    [server-name] => Unknown Server

    [gamemode] => 0

    [max-players] => 20

    [spawn-monsters] => true

    [view-distance] => 10

    [motd] => A Minecraft Server

)

can you post up a sample datafile?
