如何将代码收集到一个变量中

Question

I need to be able to get all of this information (as text) into the variable $all so that I can use it later in my script. But when I echo $all later on it doesn't work. And don't anyone say anything about the use of font tags, I'm as depressed about it as you are.

   $all = <<< STOPTHISCRAZYTHING
    echo "<br><br><textarea rows=\"30\" cols = \"100\">";
    echo "<div align=\"center\"><font size=\"7\">I Have</font></div>";
    foreach($same as $match)
        {
        echo "<img src=\"" . $match . "\">";
        }
    echo "<div align=\"center\"><font size=\"7\">I Need</font></div>";
    foreach($different as $diff)
        {
        if(!in_array($diff, $reject))
        {
        echo "<img src=\"" . $diff . "\">";
        }
        }
    echo "<div align=\"center\"><font size=\"7\">I Am Unable To Obtain</font></div>";
    foreach($retired_different as $unabletoget)
        {
        echo "<img src=\"" . $unabletoget . "\">";
        }
    echo "</textarea>";
STOPTHISCRAZYTHING;

You are looking for output buffering:

ob_start(); // Start capturing the script's output

echo "<br><br><textarea rows=\"30\" cols = \"100\">";
echo "<div align=\"center\"><font size=\"7\">I Have</font></div>";
foreach($same as $match)
    {
    echo "<img src=\"" . $match . "\">";
    }
echo "<div align=\"center\"><font size=\"7\">I Need</font></div>";
foreach($different as $diff)
    {
    if(!in_array($diff, $reject))
    {
    echo "<img src=\"" . $diff . "\">";
    }
    }
echo "<div align=\"center\"><font size=\"7\">I Am Unable To Obtain</font></div>";
foreach($retired_different as $unabletoget)
    {
    echo "<img src=\"" . $unabletoget . "\">";
    }
echo "</textarea>";

$all = ob_get_flush(); // Stop capturing output, and store the output 
// that was captured up until now into the variable $all
