File handling questions

[mendhak]

1. If I use

$fileget = file("zzz.txt"); 

Do I need to close the file after I have used it? If so, how can I close it?



2. Suppose there is a file named telephone.php. I wish to include only its 3rd and 4th lines. THe 3rd and 4th lines happen to contain PHP code by the way, and I would like that PHP code to be executed. How can I do this?

1.) You don't need to close it.

2.) erm.. the 3rd and 4th lines... You could get them using file(), but I don't know how you could get them to execute.

Btw. file() returns an array of lines, readfile() returns the file as one big string.

Thanks.

I figured out how to get the lines 3 and 4...

$filelines = sizeof($fileget);
if ($filelines > 4){
echo $fileget[3];
echo $fileget[4];
}

//$fileget was used earlier as $fileget=file("zzz.php"); for example 

But that won't execute the PHP.

Welcome back, btw.

I think I might have got it...

Write the lines to a temporary .php file, and then use include() or virtual()

Good idea. I'll try it out.
