PHP: Displaying random lines from text file

[eMonk]

I want to display thumb links randomly from a text file in php. here's a sample link:

<a href="../models/samantha/" class="tip thumb"><img src="../models/samantha/thumb.jpg" width="88" height="88"><span>Samantha</span></a>

text file will have a max of 50 lines of so. this is a temp solution until i start playing with mysql. right now im looking for a pure php solution. how can this be done?

[psili]

<?php
echo array_rand(file('../path/to/text.txt'));
?>

shit.
i suck.
thus a bump for you.

PHP Code:

<?
$a=file('filename.txt');
$b=array_rand($a);
print($a[$b]);
?>

Error: Warning: array_rand() [function.array-rand]: First argument has to be an array.

Do I need anything special in my text file?

sounds like it isn't reading the text file at all.

is the path correct?

try adding a print_r($a); after the file function to see whats in there.

[eMonk]

after adding print_r($a); it displays the thumb link but the error still remains... any ideas?

[NickSunshine]

sorry to ask:

is there a $ next to the a in the array_rand() function?

$b=array_rand($a);

short of that, no- i have no idea.

Are you editing your text file of random lines on a windows box and pushing it to a unix box or vice-versa? Maybe your text file's all torqued up. Try something simple like just a line of:

a
b
c
d
e
f

and see what happens.

that worked but it's only displaying 1 letter at a time.. i want all displayed randomly side-by-side. why doesn't the txt like my a href links?

<?

// urls.txt should be format of <a href="domain.com"><img src="domain.jpg"></a>
// 1 per line

$file = "urls.txt";
$fp = file($file);
srand((double)microtime()*1000000);
$urls = $fp[array_rand($fp)];
echo $urls;

?>

this is my fault for not completely reading your first post.

for some reason i thought you only wanted one line...

PHP Code:

<?

$a=file('textfile.txt');
array_shuffle($a);
for each($a as $line){
   print("<a href='../models/" . $line . "'><img src='../models/" . $line . "/thumb.jpg' />" . ucwords($line) . "</a>");
}

?>

$urls = $fp[array_rand($fp)];
echo $urls;

?>

displays one thumb at a time. how can we display them ALL side-by-side randomly?

}

?>

what should the txt file look like?

samantha thumb.jpg text here?

Not sure about why the HREF's aren't display but try:

$deck = file('test.txt');
shuffle($deck);
echo implode(' ',$deck);

That worked... thanks!... nice & short too...

Thanks to everyone else that helped aswell! Much appreciated!

I just hope this phrases fast when 50 or so entries are added to the txt file...

[NickSunshine]

correction: use shuffle($a); not array_shuffle($a);

i invented a function i guess :D

This eMonk thread should be pinned somewhere.

It's a very simple question that had a pretty simple solution. However, the communication between ALL involved just wasn't "right" which is the reason it took a while to solve.

There's a lesson here kids, and it's not about how to properly sniff your own ass crack, you crazy monkeys, you.

thanks again... i'm still new to php... reading my way through, "PHP and MySQL Web Development 4th edition" which is a GREAT book btw, and I knew the method wouldn't be too much lines of code for this task. I also believe it's bad practice to use PHP to display HTML.

in my opinion, it really depends on the situation.

sometimes you just gotta loop.

[Bro Media - BANNED FOR LIFE]

Easy peasy.

[Voodoo]

<?php include("myrandomtextfile.txt"); ?>

Then once a day or once a minute (Whatever you want), open myrandomtextfile.txt and replace the text in it randomly!

Dude, keep learning and asking questions. My last post was geared toward the train-wreck posts about how a client / designer / coder was fucked over because they just didn't communicate.

If you get comfortable with a skill, can communicate with a client on how to apply that skill, and can get both you and a client to agree and understand terms on the skill you apply please let me know. :-)

monkey work

i learned a couple things...

a) read the first post COMPLETELY before you try to help.
b) array_shuffle() is not a function.
c) PHP and MySQL Web Development 4th edition is a GREAT book.

I re-read the original post and still would go for a solution of outputting a random one line of a text file. That's why this thread is so perfect in it's ability to illustrate how communication is so important; for all parties.

Regardless. I like my crab cioppino served with warm garlic bread.
Huh?

PHP Code:

<?php
$lines = file('yourfile.txt');
$num = count($lines);
$r = rand(1, $num)-1;
echo $lines[$r];
?>

[eMonk]

Yeah, I could have been more clear in my original post. I never did mention to output ALL the links at once. Could have added more lines in the sample link aswell.

However this is great... GFY PHP Support Group!

[pornbling]

try this:

$fp=file('yourfile.txt');
shuffle($fp);
echo $fp[0];

This should do it. If you want to see more
echo $fp[1]; echo $fp[2]; ...

[quantum-x]

OK.
Seeing as noone else has solved this yet. (IE, haven't used the 'FILE_SKIP_EMPTY_LINES | FILE_IGNORE_NEW_LINES' flags, meaning output would be fubar)

PHP Code:

<?
$f = file('/path/to/names/names.txt',FILE_SKIP_EMPTY_LINES | FILE_IGNORE_NEW_LINES);
shuffle($f);
foreach($f as $k => $v) echo '<a href="../models/'.$v.'/" class="tip thumb"><img src="../models/'.$v.'/thumb.jpg" width="88" height="88"><span>'.strtoupper($v[0]).substr($v,1).'</span></a>'."\n";
?>

Renders:

<a href="../models/silvia/" class="tip thumb"><img src="../models/silvia/thumb.jpg" width="88" height="88"><span>Silvia</span></a>
<a href="../models/billy/" class="tip thumb"><img src="../models/billy/thumb.jpg" width="88" height="88"><span>Billy</span></a>
<a href="../models/jenna/" class="tip thumb"><img src="../models/jenna/thumb.jpg" width="88" height="88"><span>Jenna</span></a>
<a href="../models/adam/" class="tip thumb"><img src="../models/adam/thumb.jpg" width="88" height="88"><span>Adam</span></a>
