Randomizer Script Problem

deephouse

I'm trying to create unique sentences with randomizer script but the problem is that in the html output, all strings taken randomly from different .txt files are physically displayed on separate lines.

The code I'm using, is:

<?php require('header1.php'); ?> <?php require('header2.php'); ?> <?php require('header3.php'); ?>

<?php echo $header1 . $header2 . $header3 ?>

The code inside the .php files is similar (they just use according .txt files).

Example code of header2.php:

<?php
$textfile ="header2.txt";
$items = file("$textfile");
$item = rand(0, sizeof($items)-1);
$old1 = $items[$item];
$header2 = str_replace('\n', '', $old1);
?>

The contents of .txt files are just strings, each on it's own line.

The output in the browser is : String1 string2 string3
Output in the html is:

String1
string2
string3

There's no visual difference in the browser view but for specific purpose, I need the strings to be displayed all on the same line in html also.

I tried removing possible line breaks from the end of the text strings I pulled from the .txt files (/n) but it made no difference.

replace this:

$textfile ="header2.txt"; 
$items = file("$textfile"); 
$item = rand(0, sizeof($items)-1); 
$old1 = $items[$item]; 
$header2 = str_replace('\n', '', $old1);

with this

$items = file('header2.txt');
$item = trim($items[array_rand($items)]);

Thanks devinemke!

It worked like a miracle 😉

"Trim" was exactly what I was looking for, but didn't know it existed.

For other newbs who wonder what I'm talking about:

string trim ( string str [, string charlist])

This function returns a string with whitespace stripped from the beginning and end of str. Without the second parameter, trim() will strip these characters:

" " (ASCII 32 (0x20)), an ordinary space.

"\t" (ASCII 9 (0x09)), a tab.

"\n" (ASCII 10 (0x0A)), a new line (line feed).

"\r" (ASCII 13 (0x0D)), a carriage return.

"\0" (ASCII 0 (0x00)), the NUL-byte.

"\x0B" (ASCII 11 (0x0😎), a vertical tab.
