weird error with file() and implode()

[Stephen Kay]

Maybe I don't understand how to use this yet, but I was using (example):

$html = implode('', file('http://www.mysite.com/transbar.html') );
echo $html;


This works.

But if I try it on a .php file:


$html = implode('', file('http://www.mysite.com/transbar.php')) ;



I get this error:

Warning: file("http://www.mysite.com/transbar.php") - Success in
/home/cust1/usr2345/html/setuptransbar.p hp on line 47

Warning: Bad arguments to implode() in
/home/cust1/usr2345/html/setuptransbar.p hp on line 47


Can't you read in a php file this way?

Thanks,

Apparently not - I presume the script doesn't generate any output and you
really want the source?

i agree that the script may not be genarating any output. you check it
doing this:

echo '<pre>'; print_r(file('h ttp://www.mysite.com/transbar.php')) ; echo
'</pre>';

it shows up the array you got from this request. however you won't be
able to read the source once you're making a http request.

and if you want the output as a string you should use
file_get_conten ts().

Thanks, I would if my ISP was using PHP >= 4.3. It's using 4.1.

Any efficiency difference between fopen() etc. and file()?


I'm wondering if there is any advantage one way or the other to these two
methods of reading an html file:

1. using fopen and friends:

$myFile = "http://www.example.com/page.html";
$fh = fopen($myFile, 'r');
$content1 = fread($fh, filesize($myFil e));
fclose($fh);


2. using imploed, and file:

$content1 = implode('', file("http://www.example.com/page.html"));


They both seem to work equally well, but the number 1. seems to be more
robust with different file types...


Note: I can't use file_get_conten ts() because my ISP's PHP version is 4.1 or
so.
