I want to display a little php code inside Echo<<< function but I get an error,
this code is just an example. inserting {} is not working.

[code=php]
echo <<<EOD
<html>

<body>

if ($error == 1) {
echo “<center>n<font style=”color: #FF0000″>n”;
foreach($errstr as $err) {
echo “<li> ” . $err . “</li>n”;
}
echo “</font>n</center>n<br />nn”;
}

</body>
</html>
EOD;

[/code]

@MindzaiApr 26.2010 — If you want to display PHP code as part of an (X)HTML document, place the code in a single-quoted string and use htmlentities() or htmlspecialchars() to output it. You can also use highlight_string() to have the code syntax highlighted.

@UltimaterApr 26.2010 — I believe you are looking for a nowdoc but they aren't supported 'til PHP 5.3.0:

http://www.php.net/manual/en/language.types.string.php

You could store the content in a database or a separate file or use a literal string as Mindzai suggested then all you'd need to escape would be single quotes

or, my personal favorite, use [url=http://us3.php.net/manual/en/function.halt-compiler.php]__halt_compiler[/url] and avoid even having to escape those:

[code=php]
<?php
echo highlight_string(file_get_contents(__FILE__,null,null,__COMPILER_HALT_OFFSET__),true);
__halt_compiler()?>
<?php
if ($error == 1) {
echo "<center>n<font style="color: #FF0000">n";
foreach($errstr as $err) {
echo "<li> " . $err . "</li>n";
}
echo "</font>n</center>n<br />nn";
}
?>
[/code]


Some notes about __halt_compiler:

Either __halt_compiler()?> or __halt_compiler(); work well but not the combination of __halt_compiler();?> because after PHP sees the semicolon then PHP halts the compiler from that point onwards and the two characters ?> will splash to screen.

Success!
