What I'm trying to do is fairly simply, but does not seem work.
In this main page, I'm trying to insert a piece of code from another page like so.
<?php
include_once $_SERVER['DOCUMENT_ROOT'].'\attach\common.php';
$clear = False;
echo $code;
if($clear){
echo 'Clear was cleared';
}
?>
This is common.php
<?php
$code = "if(isset($_GET['n'],$_GET['c'])) {";
$code .=" echo 'Name and Country were set <br />';";
$code .=" $clear = True;";
$code .="} else {";
$code .=" echo 'An error occured <br />';";
$code .="}";
?>
How can I do this in php?
Update
<?php
include_once $_SERVER['DOCUMENT_ROOT'].'\attach\common.php';
$clear = False;
d();
if($clear){
echo 'Clear was cleared';
}
?>
<?php
function d() {
if(isset($_GET['n'],$_GET['c'])) {
echo 'Name and Country were set';
$clear = True;
} else {
echo 'An error occured <br />';
}
}
?>
Please be careful using eval() as it's a very dangerous way of achieving what you want.
Why can't you just put code in common.php instead of putting it up as a string inside variable?
i.e. common.php:
<?php
if(isset($_GET['n'],$_GET['c'])) {
echo 'Name and Country were set <br />';
$clear = true;
} else {
echo 'An error occured <br />';
}
?>

In the case where you'd really need to do so:
Use eval() to parse $code. That's because your code is a string variable and not actual code.
<?php
include_once $_SERVER['DOCUMENT_ROOT'].'\attach\common.php';
$clear = False;
eval($code);
if($clear){
echo 'Clear was cleared';
}
?>
You don't put code in a string to include it in another file, just put the code as it is.
common.php should be
<?php
if(isset($_GET['n']) && isset($_GET['c'])) {
echo 'Name and Country were set <br />';
$clear = True;
} else {
echo 'An error occured <br />';
}
?>
