How to display special characters in PHP
After much banging-head-on-table, I have a bit better understanding of the issue that I wanted to post for anyone else who may have had this issue.
While the UTF-8 character set will display special characters on the client, the server, on the other hand, may not be so accomodating and would print special characters such as à
and è
as �
and �
.
To make sure your server will print them correctly, use the ISO-8859-1
charset:
<?php
/*Just for your server-side code*/
header('Content-Type: text/html; charset=ISO-8859-1');
?>
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"><!-- Your HTML file can still use UTF-8-->
<title>Untitled Document</title>
</head>
<body>
<?= "àè" ?>
</body>
</html>
This will print correctly: àè
Edit (4 years later):
I have a little better understanding now. The reason this works is that the client (browser) is being told, through the response header()
, to expect an ISO-8859-1
text/html file. (As others have mentioned, you can also do this by updating your .ini
or .htaccess
files.) Then, once the browser begins to parse that given file into the DOM, the output will obey any <meta charset="">
rule but keep your ISO characters intact.
So I try htmlspecialchars() or htmlentities() which outputs <p>Résumé<p> and the browser renders <p>Résumé<p>.
If you've got it working where it displays Résumé
with <p></p>
tags around it, then just don't convert the paragraph, only your string. Then the paragraph will be rendered as HTML and your string will be displayed within.
You can have a mix of PHP and HTML in your PHP files... just do something like this...
<?php
$string = htmlentities("Résumé");
?>
<html>
<head></head>
<body>
<p><?= $string ?></p>
</body>
</html>
That should output Résumé
just how you want it to.
If you don't have short tags enabled, replace the <?= $string ?>
with <?php echo $string; ?>
In PHP there is a pretty good function utf8_encode() to solve this issue.
echo utf8_encode("Résumé");
//will output Résumé instead of R�sum�
