Using multiple quotations in PHP codes

Question

Let's say this is my script down here, as you can see I've used multiple " and '. These quotations conflict in ending the current php variable, so it basically sees this:

$message = "<?php echo '<div class="

As a string, whilst the quotation is only to define the class, not to end the variable. I've tried using ' but then it conflicts with the echo, so I'm kinda stuck at the moment.

    <?php

    $message = "
    <?php
    echo '<div class="gebruiker">';
    $fh = fopen('_gebruiker.txt','r');
            while ($line = fgets($fh)) {
              echo($line);
            }
            fclose($fh);
    echo '</div>';
    ?>
    ";

How can I use multiple quotations in one PHP script without them having conflicts.

seems like you're doing scary stuff... – NDM Jan 15 '15 at 13:31 — NDM, Jan 15 '15 at 13:31

Adding a backslash so PHP can recognize just only double quotes or quotes when escaped.

Example:

echo "<div class=\"gebruiker\">";

Escape orgies result in rather unreadable code. Also, he needs to escape variables, too, if he's using double quotes. – ThiefMaster Jan 15 '15 at 13:24
This is the easiest way he can use it. Also, there other ways we can treat it. But for a specific simple line, escaping with backslash suits better. You just cannot disregard my answer and this option. – bcesars Jan 15 '15 at 13:45
I agree with @ThiefMaster, still this is an easy solution, for an asked question that has some flaws in its approach (IMHO). – Masiorama Jan 15 '15 at 13:45
But he cannot use that solution! His example string contains single quotes and dollars, so he at least needs to escape the dollars, too... – ThiefMaster Jan 15 '15 at 13:47
@ThiefMaster Yes that is true, the variable $fh was not taken in the code, it simply removes it. Still looking for a solution for that, but atleast I got one of the problems solved now – branco holtslag Jan 15 '15 at 14:15

If you use single quotes outside, you need to escape all single quotes inside, but can use double quotes and the dollar char without escaping.
If you use double quotes outside, you need to escape all double quotes and dollar chars inside, but can use single quotes without escaping.
If you use a heredoc string, you need to escape dollar chars but can use both single and double quotes without escaping.
If you use a nowdoc string, you do not need to escape anything unless you have FOO; in the string at the beginning of a new line.

So the solution is to use a nowdoc string:

$message = <<<'EOF'
your stuff with " or ' or $ here!
EOF;

I suggest using either Heredoc or Nowdoc

Example

$foo = 'test';

// Heredoc
$here = <<<HERE
I'm here, $foo!
HERE;

// Nowdoc
$now = <<<'NOW'
I'm now, $foo!
NOW;

Heredoc will print the contents of $foo when echoed while Nowdoc will simply echo $foo.

You can escape the quotes with a slash character like so: \"

This should work, you can't open Php tag without closing before.

<?php

$message = '<div class="gebruiker">';
$fh = fopen('_gebruiker.txt','r');
        while ($line = fgets($fh)) {
          $message .=$line.'<br/>';
        }
        fclose($fh);
$message.='</div>';
echo $message;
