Receiving Non-ASCII Characters with POST Method
This section provides a tutorial example on how enter non-ASCII characters in HTML forms and receive them correctly with the POST method. The HTML form is using the iso-8859-1 encoding.
To test the POST method, I wrote the following script, InputIsoPost.php:
<?php # InputIsoPost.php #- Copyright 2009 (c) HerongYang.com. All Rights Reserved. # #- Promoting CGI values to local variables global $r_English, $r_Spanish, $r_Korean, $r_ChineseUtf8; global $r_ChineseGb2312; import_request_variables("GPC","r_"); #- Generating HTML document print("<html>"); print('<meta http-equiv="Content-Type"' .' content="text/html; charset=iso-8859-1"/>'); print("<body>\n"); print("<form action=InputIsoPost.php method=post>"); print("English ASCII: <input name=English" ." value='$r_English' size=16><br>\n"); print("Spanish UTF-8: <input name=Spanish" ." value='$r_Spanish' size=16><br>\n"); print("Korean UTF-8: <input name=Korean" ." value='$r_Korean' size=16><br>\n"); print("Chinese UTF-8: <input name=ChineseUtf8" ." value='$r_ChineseUtf8' size=16><br>\n"); print("Chinese GB2312: <input name=ChineseGb2312" ." value='$r_ChineseGb2312' size=16><br>\n"); print("<input type=submit name=submit value=Submit>\n"); print("</form>\n"); #- Outputing input strings back to HTML document print("<hr>"); print("<pre>"); foreach ($_POST as $k => $v) { print "$k = ($v)\n"; } print("</pre>"); print("</body>"); print("</html>"); #- Dumping input strings to a file $file = fopen("\\temp\\InputIsoPost.txt", 'ab'); $str = "------\n"; fwrite($file, $str, strlen($str)); foreach ($_REQUEST as $k => $v) { $str = "$k = ($v)\n"; fwrite($file, $str, strlen($str)); } fclose($file); ?>
If you test this script with Internet Explorer, you will get the same result as InputIsoGet.php.
I was looking for a way to dump the input strings submitted by the POST method. But I could not find the right function to do this.
