Search notes:
PHP code snippets: the urldecode() function
urldecode() can be used to decode
percent encoded characters of an
URI .
The following example tries to demonstrate that the values in the super global
associative array $_GET is already url-decoded, but not the the value of
$_SERVER ['QUERY_STRING'].
<?php
print('<html><head>
<meta charset="utf-8">
<title>urldecode</title></head><body>
');
printf('<form>
<input type="text" name="words" value="%s" />
<input type="submit"/>
</form>', htmlentities(
array_key_exists('words', $_GET) ? $_GET ['words'] : "O'briän & company"
)
);
print("<hr><table border=1 style='border-collapse:collapse'>");
printf("<tr><td>\$_GET['words']</td><td>%s</td></tr>" , htmlentities(array_key_exists('words' , $_GET ) ? $_GET ['words' ] : "") );
printf("<tr><td>\$_SERVER['QUERY_STRING']</td><td>%s</td></tr>" , htmlentities(array_key_exists('QUERY_STRING', $_SERVER) ? $_SERVER['QUERY_STRING'] : "") );
printf("<tr><td>urldecode(\$_SERVER['QUERY_STRING'])</td><td>%s</td></tr>", urldecode(htmlentities(array_key_exists('QUERY_STRING', $_SERVER) ? $_SERVER['QUERY_STRING'] : "")));
print("</table>");
print("</body></html>");
?>
