Question

I’m trying to use PHP variables into echoed file, and couldn’t get where is a trouble at first using that script:

$head = new mod_head("head.php");
$id="ASDSSgdfsfsdfS";
echo $head;

mod_head class:

class mod_head
{
private $out="";
function __construct($arg)
{
$this->out=$this->parts($arg);
}
public function __toString()
{
return $this->out;
}
private function parts($file)
{
return fread(@fopen(PATH . "parts/".$file, 'r'), filesize(PATH . "parts/".$file));
}
}

and the file is “head.php”

<h1><center style="background:orange; border-radius:15px;">LOGO</center></h1>
<br><?php print_r($id)?>
<div>BANNER <div>$id <?php echo $id ;?></div></div>

i dont want to create global vars, why it doest echo $id var?

Answer 1

First, you’re going to need to parse the file, not just read it. The second problem you’ll have is a scope issue. $id is outside of the scope of the parts() function. In order to return the contents of the required file instead of just printing it I’ve used the output control functions

Try changing your parts function to this:

private function parts($file)
{
    ob_start();
    require(PATH . "parts/".$file);
    $output = ob_get_contents();
    ob_end_clean();
    return $output;
}

To fix the scope issue try changing $id="ASDSSgdfsfsdfS"; to $head->id = "ASDSSgdfsfsdfS";, then change head.php to be the following:

<h1><center style="background:orange; border-radius:15px;">LOGO</center></h1>
<br><?php print_r($this->id)?>
<div>BANNER <div>$id <?php echo $this->id ;?></div></div>
