PHP Question

[version4]

I've been using the below php script to randomly take a single line from the file test.txt and insert it into a webpage.

Could someone tell me how I could add a variable X to this script so that I can set it to whatever I want, eg x=5. In this case, the script would take 5 lines from test.txt and insert it into a webpage.

Thanks


<?php
$file = "test.txt";
$file_Content = file($file);

if (count($file_Content) > 0) {
$line = $file_Content[rand(0,count($file_Content)-1)];

echo $line;
}
?>

<?php
$file = "test.txt";
$file_Content = file($file);

if (count($file_Content) > 0) {
$line = $file_Content[rand(0,count($file_Content)-1)];

echo $line;
}
?>

5 lines after each other? or each one random?

PHP Code:


<?php
    $file        = "test.txt";
    $file_Content    = file($file);

    $j = 0;
    $limit = 5;

    while ($j < $limit) {
    
      if (count($file_Content) > 0)    {
          $line = $file_Content[rand(0,count($file_Content)-1)];
    
      echo $line;
      }
      
      $j++;

  }
?>

Try that. Chances are it will spit out the same line multiple times, but you could get around that with with a few extra lines of code.

$line = $file_Content[rand(0,count($file_Content)-1)];

echo $line;

<?php
$x = 5; // Your X variable
$file = "test.txt";
$file_Content = file($file);

if (count($file_Content) > 0) {

for($i=0;$i<$x;$i++){

$line = $file_Content[rand(0,count($file_Content)-1)];

echo $line; }
}
?>

[Lane]

$file_Content = file("test.txt");
if (count($file_Content) > 0)
for($i=0;$i<5;$i++)
echo $file_Content[rand(0,count($file_Content)-1)];

Bigfish,

Thanks, this works well.

Two things I thought of after running your script.

1. How can I avoid duplicate lines being taken from test.txt. I'd like X number of lines, all are different.

2. How to add a break between the lines of data so that each line of text from test.txt is on it's own line.

Currently the output is as follows:

google yahoo google altavista msn

Would like it as (note there are no duplicates and each is on it's own line):

lycos
google
yahoo
altavista
msn

Thanks

That code looks familiar
