$_POST don't give any result

I try with a little script on php but it doesn't give any result.

example.html:

<form action="action.php" method="post">
 <p>URL <input type="text" name="url"></p>
  
 <p><input type="submit" value="OK"></p>
</form>

action.php:

<html>
  <? echo $_POST['url'];?>
</html>

Even when the field of url is full, it doesn't give any result.

First be sure that action.php is located in the same directory as the html file containing the form.

Second, change your php code to the following:

<?php echo $_POST['url']; ?>

Regarding short tags:

When PHP parses a file, it looks for opening and closing tags, which are which tell PHP to start and stop interpreting the code between them.

PHP also allows for short open tag http://php.net/manual/en/language.basic-syntax.phptags.php

Short tags example:

<? echo $variable ?>
<?= $variable ?>

These do not contain the opening "<?php" and is discouraged per the quote above.

However, starting in 5.4 the second version of the short tags will always be on regardless of the short tag setting in the php.ini. That means the 

 <?= $variable ?>

will always be available.

How to use short tags prior to PHP 5.4

Open you php.ini file, search for "short_open_tag" and change the value to "1". http://php.net/manual/en/ini.core.php#ini.short-open-tag

you should use <?php echo $_POST['url']; ?> this is standard tags instead <? echo $_POST['url'];?>

<? ?> is short tags, need short_open_tag enabled in php.ini
