[SOLVED] Pull multiple random lines from text file

[rachelk]

I've searched around and found threads on doing this, but I'm a beginner so I can't figure out how to do it with more than one line and not have a line repeated anywhere... I have a text file set up like

 

words-here

and-here

 

etc and just want to pull 10 random lines from it.

 

Any help is much appreciated!

put your text in array and pull the lines up randomly.

Thank you for your reply.

 

I've tried many codes pulling random lines from arrays and they all end up with some lines being repeated, so I'm wondering if there's a way to avoid that.

<?php
$lines = file('filename.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
shuffle($lines);
$ten = array_slice($lines, 0, 10);
echo '<pre>' . print_r($ten, true) . '</pre>';
?>

Thanks for that, it works perfectly with outputting 10 lines, but I can't figure out how to use it in my situation.

 

Each line in that text file is an image url, so I'm looking to have < img src = " print line here " > for each of the ten lines instead of the lines outputting in a list. I've googled quite a bit but can't figure out how I can do this, or if it's even possible.. every code I try just outputs a list.

All you would need is these two lines of code... then each place there is an image url, replace it with echo $lines[0], echo $lines[1], echo $lines[2], and so on.

 

Sounds too simple, maybe I'm misunderstanding

 

<?php
$lines = file('filename.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
shuffle($lines);
?>

Just loop through the array:

 

<?php
foreach ($ten as $url) {
echo '<img src="' . $url . '" alt="" />' . "\n";
}
?>
