echo help

[newbtophp]

Im haivng some trouble when i place.

 

echo "\x64\x69\"; and open it in a browser it echos text.

 

but when i put that some code in a field and submit it just echos whats been submitted.

 

<?php
$code = stripslashes($_POST['code']);
$submit = $_POST['submit'];
if($code == "") echo "";
else {


echo "$code";


}
?>

Not entirely sure what you want to accomplish here but I would change your if condition to read cleaner by doing this.

 

if (!$code == "") {
    echo $code;
}

 

The ! means 'NOT'... so it will only run the code block if $code is NOT "". 

 

Please provide more info on what you want to accomplish and I will try to help.

are you trying to make the code you submit to be treated as php code not as plain text?

if you want to parse what has been submit as php then use eval

$code = stripslashes($_POST['code']);
$submit = $_POST['submit'];
if($code == "") 
echo "";
else
eval($code)";

Thanks for all your replies, not still no luck.

 

Let me further explain, if you copy this code, save it and open it:

 

<?php
echo "\x64\x69\x73\x70\x6C\x61\x79";

?>

 

You'll get:

 

display

 

 

I've created a form which uses $_POST to submit \x64\x69\x73\x70\x6C\x61\x79 (code) and echo it which is supposed to give: display

 

But is just echoing whats been inserted.
