Make array with txt file content

Peuplarchie · 07-16-2008, 06:16 PM

Good day to you all,
Here is a piece of code from my login script.

PHP Code:


			

$data=array("user1"=>array("url"=>"Index/admin-index.php","password"=>"pass1"),
            "user2"=>array("url"=>"file2.php","password"=>"pass2"));

As you can see the array is not a generated array, in other word, the script should read a txt file, each line would have, a password, username and a url.
like :
Jack=>Daniel=>Director/index.php
Angolina=>Joli=>Pretty/index.php
Mike=>Lee=>User/index.php

Thanks !
Franck

You could use fscanf...

I would use explode to do this, although fscanf looks a lot easier - I've never seen it before and I'd recommend it now!

PHP Code:


			
<?php

/**
 * Explode method
 */

// First explode the file into seperate lines and loop through to remove empty lines, etc
$file = file_get_contents('file.txt');
$file = explode("\n", $file);

$lines = array();

foreach($file as $line)
{
     // Checks a line is not empty (after whitespace is removed) or not a comment (using .ini style comments)
     if(!empty(trim($line)) && substr($line, 0, 1) != ';')
     {
          $lines[] = trim($line);
     }
}

// Next parse the data from the line and add to the $data array
$data = array();
foreach($lines as $line)
{
     $line = explode('=>', $line);
     // Check the line is an array and hasn't done something silly
     if(is_array($line))
     {
          $data[] = $line;
     }
}

print_r($data);


/**
 * fscanf method
 */
$file = fopen('file.txt', 'r');

$data_array = array();

while($data = fscanf($file, '%s=>%s=>%s'))
{
     list($name1, $name2, $file) = $data;
     
     // Example
     $data_array[$name1] = array($name2, $file);
}

fclose($file);

print_r($data_array);

?>

As you can see the explosion method is much more memory intensive but shows you how a file could be parsed. fscanf is much more simple to use.
