note 74337 added to function.urlencode

Uniform Resource Locators (URL) & XHTML compliance Reference to http://www.rfc-editor.org/rfc/rfc1738.txt The following is compliant for a redirect (but not for a link in <a>anchor</a> tags): <?php $url = "www.some.com/query.php" foreach ($aQuery as $key => $val){ $aTemp[] = urlencode($key) . '=' . urlencode($val); } $url_query_string = join('&', $aTemp); header("Location: $url . $url_query_string" ); ?> For links the '&' in the join must be an HTML entity to be XHTML compliant. <?php $url = "www.some.com/query.php" foreach ($aQuery as $key => $val){ $aTemp[] = urlencode($key) . '=' . urlencode($val); } $url_query_string = '?' . join(htmlspecialchars('&'), $aTemp); echo '<a href="' . $url . $url_query_string . '>Compliant</a>' ; ?> For both examples the $aQuery is an associative array: <?php $aQuery = array( "example_one" => "redirect", "example_two" => "link" ); ?> ---- Server IP: 194.145.210.3 Probable Submitter: 81.158.78.51 ---- Manual Page -- http://www.php.net/manual/en/function.urlencode.php Edit -- https://master.php.net/note/edit/74337 Del: integrated -- https://master.php.net/note/delete/74337/integrated Del: useless -- https://master.php.net/note/delete/74337/useless Del: bad code -- https://master.php.net/note/delete/74337/bad+code Del: spam -- https://master.php.net/note/delete/74337/spam Del: non-english -- https://master.php.net/note/delete/74337/non-english Del: in docs -- https://master.php.net/note/delete/74337/in+docs Del: other reasons-- https://master.php.net/note/delete/74337 Reject -- https://master.php.net/note/reject/74337 Search -- https://master.php.net/manage/user-notes.php
