using fwrite to create PHP files

[Vince Lamonica]

Hi all,

I wish to use fwrite() to create a small PHP file. So far, when I attempt
to do this, php parses the contents of the file that fwrite needs to
create. Eg, I have this:

$new_id = mysql_insert_id();
// create brand new file
$new_file = fopen("/var/www/html/$sitename/$submitted_url", "w");
$new_file_content = "\n"
.." <?php \n"
.." if ($_GET['preview'] == \"y\") { \n"
.." readfile(\"http://www.foo.bar/${'sitename'}.display?${'sitename'}id=$new_id&prev iew=y\"); \n"
.." } else { \n"
.." readfile(\"http://www.foo.bar/${'sitename'}.display?${'sitename'}id=$new_id\"); \n"
.." } \n"
.." ?>";

write($new_file, $new_file_content);
fclose($new_file);

Note that $sitename is defined earlier in the script.

I know that $new_id and $sitename get expanded, as I tried this:

$new_file_content = "hello world. Look at my ${'sitename'}.display and my $new_id";

and the new file was created with the above text and the two vars
expanded. My problem lies in the fact that I need to put "<?php" tags
inside the contents of $new_file_content. I'm not sure how to do that w/o
generating lots of errors. As you can see in my above example, I've tried
to escape the double quotes, but that didn't seem to help. PHP insists on
processing the "if" line instead of ignoring it.

I'm running 4.3.3 under apache 1.3.28.

Any help would be most appreciated!

To answer your question, you probably can do
$new_file_content="<"."?"."php\n" . [...] . "?".">";

But why in the world do you need this complication?

Hi,

Ik think the parser is teasing you.
Try this workaround:

$myphpopentag = "";
$myphpopentag .= "<";
$myphpopentag .= "?php";

and use that $myphpopentag instead where needed.

Try the same for the closetag.

Hope that helps,

regards,
Erwin

Vince,
You also need to escape the $, so instead of
.." if ($_GET......
use
.." if (\$_GET.....

You may have to escape the single quotes.

I have written two pretty lame code generators. The first one did not use
"templates", the second one does. You've got the lines of code in your
"builder" script. I recommend moving those lines of code out, and put them
into a template, then use str_replace() to change the template as/where
needed.

You need to escape the dollar signs in your string.

.." if (\$_GET['preview'] == \"y\") { \n"

[Chris Sherwood]

this is a sample of what I do when I need to write a php file

$stringtowrite = "<?PHP\n// Bulletin Board
forum\n$"."ForumId=".$tabletofind.";\n";

$stringtowrite .=
"$"."ForumActive='1';\n$"."ForumName='".$sportname ."';\n";

$stringtowrite .= "$"."ForumDescription='".$sportname." forum';\n";

$stringtowrite .= "$"."ForumConfigSuffix='';\n";

$stringtowrite .= "$"."ForumFolder='0';\n";

$stringtowrite .= "$"."ForumParent='0';\n";

$stringtowrite .= "$"."ForumLang='lang/english.php';\n";

--- and so on until finally

$fd=fopen($final_destination,"w") or die ("file won't open");
/*if ($fd===false)
{
echo "file create failed";
exit();
//return;
} */
fwrite($fd,$stringtowrite);
fclose($fd);
