Comparing output of array

[herghost]

Hi all

 

I am having massive problems comparing the out put of array, basically my end result is to choose a selected option on a drop down in a form.

 

I am trying to compare the output of ['allow-nether'] which is either true or false in my file.

 

Here is what I have tried

 

//code to get file contents

 

$file_handle = fopen("saves/server.properties", "rb");

$vars = array();
while (!feof($file_handle) )
{
   $line_of_text = fgets($file_handle);
   $parts = explode('=', $line_of_text);
  
   //if date not required
   if ( !isset($parts[1]) )
   {
      continue;
   }
   $vars[$parts[0]] = $parts[1];
}

 

<?php
//allow nether =false in file

echo "1 " .$vars['allow-nether'];

if ( $vars['allow-nether'] == true ) { echo '<br>2 selected="selected"';} 
if ( $vars['allow-nether'] == false ) { echo '<br>3 selected="selected"';}
if ( $vars['allow-nether'] == "true" ) { echo '<br>4 selected="selected"';}
if ( $vars['allow-nether'] == "false" ) { echo '<br>5 selected="selected"';}

if ( $vars['allow-nether'] === true ) { echo '<br>6 selected="selected"';} 
if ( $vars['allow-nether'] === false ) { echo '<br>7 selected="selected"';}
if ( $vars['allow-nether'] === "true" ) { echo '<br>8 selected="selected"';}
if ( $vars['allow-nether'] === "false" ) { echo '<br>9 selected="selected"';}
?>

 

which outputs:

 

1 false 
2 selected="selected"

 

and if I set the file to allow-nether=true

 

<?php
//allow nether =true in file

echo "1 " .$vars['allow-nether'];

if ( $vars['allow-nether'] == true ) { echo '<br>2 selected="selected"';} 
if ( $vars['allow-nether'] == false ) { echo '<br>3 selected="selected"';}
if ( $vars['allow-nether'] == "true" ) { echo '<br>4 selected="selected"';}
if ( $vars['allow-nether'] == "false" ) { echo '<br>5 selected="selected"';}

if ( $vars['allow-nether'] === true ) { echo '<br>6 selected="selected"';} 
if ( $vars['allow-nether'] === false ) { echo '<br>7 selected="selected"';}
if ( $vars['allow-nether'] === "true" ) { echo '<br>8 selected="selected"';}
if ( $vars['allow-nether'] === "false" ) { echo '<br>9 selected="selected"';}
?>

 

Gives:

 

1 true 
2 selected="selected"

 

 

What am I doing wrong?

Your values in the file are strings AND your code is not removing the end-of-line (EOL) character(s), so your values are actually "trueEOL" and "falseEOL" and the string comparisons don't match and the string replace still leaves the EOL character(s).

 

You need to trim the data or otherwise remove the EOL character(s) before you use the data.

Thanks mate, that really helped :-)
