Using non-executing (plain-text) PHP code in a variable

I'd like to use non-parsing/executing PHP code in a variable, as I will be writing the content to a file where it will actually be parsed at a later time.

$setting['content'] .='
<?php
if ( ! defined( 'INCLUDED' ) )
{
      print "<h1>Invalid access</h1>";
      exit();
}
else{
$variable =\'';

$setting['content'] .= 'content here';
$etting['content'] .= '\';
}
?>';

In the end, I want $settings['content'] to have a value of something like:

<?php
if ( ! defined( 'INCLUDED' ) )
{
      print "<h1>Invalid access</h1>";
      exit();
}
else{
$variable ='content here';
}
?>

I need most of everything to stay intact the way I have it, using .= becuase it's going to be a class system and the only thing that will change for the different files is the "content here" area. It's important to keep in mind, I am NOT trying to parse any of the value of the variable. I just want to collect all of the values so I can write that to a file that will actually be parsed as normal.

you can use eval command to evaluate some string as php code later, for example in your case do :
<?php
$setting['content'] .='
if ( ! defined( \'INCLUDED\' ) )
{
print "<h1>Invalid access</h1>";
exit();
}
else{
$variable =\'\';

$setting[\'content\'] .= \'content here\';
$etting[\'content\'] .= \'\';
}'; //storing content in your $setting array

eval($setting['content']); //evaluating
?>

this also works when writing to a file
<?php
$setting['content'] .='
if ( ! defined( \'INCLUDED\' ) )
{
print "<h1>Invalid access</h1>";
exit();
}
else{
$variable =\'\';

$setting[\'content\'] .= \'content here\';
$etting[\'content\'] .= \'\';
}'; //storing content in your $setting array

$file = fopen('textfile.txt', 'w');
fwrite($file, $setting['content']);
fclose($file);

?>
open your textfile.txt and your result will be :
if ( ! defined( 'INCLUDED' ) )
{
print "<h1>Invalid access</h1>";
exit();
}
else{
$variable ='';

$setting['content'] .= 'content here';
$etting['content'] .= '';
}

I just needed to use escaped single quotes as quad341 said. Thanks :)
