Echo an $_POST in PHP
How can I print a $_P开发者_如何转开发OST
?
Example:
echo $_POST['data'];
This returns nothing...
You can also wrap your code with <pre>
tags to make your array prints out nicer instead of just 1 continuous line. A trick that was shown by a member on this site.
<pre>
<?php var_dump($_POST); ?>
</pre>
Your code is correct.
You can use either:
var_dump($_POST);
or
print_r($_POST);
to print out the entire POST array for debugging.
You can only show the values of keys that exist. array_keys()
returns an array containing the keys that exist in the array. If there is no output for a key despite the fact that the key exists then the array may contain an empty value for that key.
