u used file_get_contents too, and it still looses formating file_get_contents – Bidden

Answer 1

The implode defaults to an empty string. You should call implode something like this:

  $string = implode("<br>", $contents);

Squadron

Answer 2

You have to add HTML line break elements to the physical line breaks. You could use the nl2br function to do that:

foreach (glob("*.txt") as $filename) {
    echo nl2br(file_get_contents($filename));
    echo "<br></br>";
}

Additionally I would use the file_get_contents function rather than the combination of file and implode.

Cyte

I don’t like going a long way round. But using implode in this case would be fine as well. – Cyte

@Bidden simplicity, nl2br basicly does the same as impload('<br />', $var) but it requires less arguments and therefor looks cleaner in the code so why not just use it. – Endora

Implode in this case probably performs better. nl2br has no idea how many new lines there are and so probably has to use a string builder to make the output string. Implode can just allocate filesize + length ('<br>')*(count(lines)-1) chars immediately and then copy the data into place. – Chafin

Answer 3

If this isn't part of an HTML document, you need to change the content type:

<?php
header("Content-Type: text/plain");
foreach (glob("*.txt") as $filename) { 
  readfile($filename);
}
?>

If it is part of an HTML document, just do this:

<pre>
<?php
foreach (glob("*.txt") as $filename) { 
  readfile($filename);
}
?>
</pre>

Alternatively you can replace newlines with breaks:

<?php
foreach (glob("*.txt") as $filename) { 
  $str = file_get_contents($filename);
  echo preg_replace('!\r?\n!', '<br>', $str);
}
?>

Practically

You don't want the content type in the second and third examples. – Roof

By far the most underrated answer for this question. – Deberadeberry

Answer 4

embed the text file content between <pre></pre> tags

Orientation

That probably won't be enough. – Squadron

Answer 5

As several of the other responses mentioned, it greatly depends upon the page in which you're displaying the output.

Raw Text Output

If you're not adding any other content or HTML to the page. Simply change the HTTP Content-Type header to "text/plain"; that is:

header('Content-Type: text/plain');
echo file_get_contents('path/to/file');

As always, HTTP headers must be sent before any content is sent to the browser.

(X)HTML Output

Replacing \n's with <br/> will not fix whitespace truncation issues; that is, the removal of adjacent spaces and/or tabs. The easiest way to get around this, also as previously mentioned, is to use the <pre> tag to enclose the contents of the file. Unfortunately, this is not enough to satisfy XHTML. There are a number of symbols that are invalid in XML unless they are properly escaped, notably including: &, <, and >.

Thankfully, this is also an easy fix using the str_replace method:

$raw = file_get_contents('path/to/file');
echo '<pre>';
echo str_replace($raw, array('>','<','&','%'), array('&gt;','&lt;','&amp;','&#37;'));
echo '</pre>';

Answer 6

file() returns an array with the lines of the file.

If you implode those without glue there will be no linebreaks at all.

So, either get the contents unmodified using file_get_contents() (which gives you a string), or glue the implode with newline or

Meseems

Answer 7

Peter Stuifzand had the right idea, passing a second argument to the implode function, so I won't address that. What I will point out is that your own echo "<br></br>"; code does not produce valid HTML. If you're doing HTML and want 2 line breaks, do echo "<br><br>"; and if you're doing XHTML and want 2 line breaks, do echo "<br/><br/>";. Otherwise, if you only want 1 line break, the HTML br tag does not have a closing tag, so </br> is not necessary in either case.

Answer 8

write your text in a .txt file and redirect to url corresponding to that file

php example code

contents of allow.txt are

Authorized=True
Duration=1
OutputAnalog=NO_PLAYBACK
OutputDigital=NO_PLAYBACK

contents of deny.txt are

Authorized=False
Duration=0
OutputAnalog=NO_PLAYBACK
OutputDigital=NO_PLAYBACK

contents of php file

<?php
$user = $_REQUEST['username'];
$pass = $_REQUEST['password'];
$contentId = $_REQUEST['contentId'];
ob_start(); // ensures anything dumped out will be caught

 // do stuff here
allowUrl = 'http://localhost/allow.txt'; // this can be set based on whatever
$denyUrl = 'http://localhost/deny.txt';
// clear out the output buffer
while (ob_get_status())
{
    ob_end_clean();
}

// no redirect
if($user == "xyz" && $pass == "xyz")
header( "Location: $allowUrl" );
else
header("Location: $denyUrl");
?>

Answer 9

Or you could just put it into a textarea like this:

<?
$file = 'file.txt';
$contents = file($file); 
$string = implode("",$contents); 
echo '<textarea readonly style="width:100%; height:200px;">';
echo $string;
echo "</textarea><br></br>";
?>

But only if you can and it turns out right.
