writing code to file

[gmdavis]

I'm sure this is going to seem obvious once someone explains it to me but...

I'm have some code that writes updated html files to my server. I want to embed some php code in the html. I've been experimenting with how to escape the code so it doesn't get parsed with the folowing results:

<?
$string = "<";
$string .= "?php echo(\"php is great\"); ?>";
echo "$string";
?>

Will output NOTHING.

I tried escaping the first echo

$string = "\<";

but all this output is only

\"

.

If it delete the "<", the rest of the code is output fine.

<?
$string = "";
$string .= "?php echo(\"php is great\"); ?>";
echo "$string";
?>

Will output:

?php echo("php is great"); ?>

If I comment out the rest of the sting leaving only "<", I get this weird result:

"; echo "$string"; ?>

How do I get complete PHP code into a file written by PHP?

Are you running this script in a browser? If so, you should try viewing the HTML source of the resulting page. The reason nothing is displayed is that the browser doesn't know how to handle <?php tags, and therefore doesn't display them.

Also, if you really want to save the output to a file, you should do something like this:

<?php
$file = "foo.php";
$fp = fopen($file,'w+');

$string .=  "<?php echo(\"php is great\"); ?>";
fwrite($fp,$s);


fclose($fp);
?>

Like I said "I'm sure this is going to seem obvious once someone explains it..."

You are correct. I forget that html also uses "<" to open tags. Viewing the source does reveal the expected result.

Thanks
