(HELP) PHP to get random line from text file for video embed

Recommended Posts

This is a section of my code that goes and gets videos from any video site. What I’m having issues with is having it post a random title, that are all in a text file called titles.txt. What I’m wanting to accomplish is have my script go pull the video embed code, the duration, the tags, etc. Which all works fine until I get to the title part where it pulls locally from the server from the text file. I'm not an advance programmer so not sure if I am even approaching this correct way. Here is the code I have that is responsible for putting the title in. I appreciate your help.

$video = array(
user_id => $this->user_id,
status => $this->status,
site => my site’,
id => ‘’,
embeddable => true,
url => ‘’,
titles => ‘’,
title => ‘’,
description => ‘’,
tags => ‘’,
category => ‘’,
thumbs => array(),
duration => 0,
embed => ‘’
);

function random_title ()
{
$titles = file (“titles.txt”, FILE_IGNORE_NEW_LINES);
$num = rand (0, intval (count ($titles) / 3)) * 3;
return ucwords($titles[$num]);
}

//Title
if(preg_match(’/title="(.*?)"/’, $match, $matches_title)) {
$video[‘title’] = random_title().  - My site name’;
} else {
$this->errors[] = Failed to get video title for ‘.$video[‘url’].’!’;
if (!$this->debug) continue;
else $debug_e[] = TITLE’;
}

Perhaps you could explain the rationale behind this method for getting the title...

$num = rand (0, intval (count ($titles) / 3)) * 3

@Barand To be honest I had found that code online that I used with a Youtube script. I'm not even sure if that is the correct way to do it. I'm learning php so really kinda just fumbling through this.

It isn't a sound method. Suppose you have 3 titles. 

intval(count($titles)/3) = 1, so you now get a random integer between 0 and 1 which you multiply by 3. Therefore $num will be 0 or 3. The titles are indexed 0, 1 and 2. IE index 3 doesn't exist. See the problem?

Use array_rand()

$random_title = $titles[array_rand($titles)];

@Barand So are you saying replace this line:

$num = rand (0, intval (count ($titles) / 3)) * 3;

With this line:

$random_title = $titles[array_rand($titles)];

So I would end up with this:

function random_title ()
{
$titles = file (“titles.txt”, FILE_IGNORE_NEW_LINES);
$random_title = $titles[array_rand($titles)];
return ucwords($titles[$num]);
}

I tried to run my script with that but it still does not work. Below is the entire php file for this script.

<?php

	public function __construct($url, $user_id, $category, $status, $debug) {

Stop blindly copying and pasting. Apply a little thought to what the code is doing. You'll learn more that way.

function random_title ()
{
    $titles = file (“titles.txt”, FILE_IGNORE_NEW_LINES);
    $random_title = $titles[array_rand($titles)];
    return ucwords($random_title);
}
