Converting print_r() output to an array

Hey everyone, I was pretty sure there was an easy built-in solution for
what I want to do, but I've been googling around with no luck.
Basically, I just want to take a string containing the output of
print_r() and convert it back into an array again.

That is possible, right?  If so, how do I go about it?  If not, what's a
quick and easy way to parse a string and turn it into an array (I don't
necessarily need the string to be in the format print_r returns).

Thanks!

James

Re: Converting print_r() output to an array

first off, if you pass print_r($var, true) it will return it instead
of printing it. if you go that route.

have you looked at var_export() ?

Re: Converting print_r() output to an array

Hi,

May be you want to take a look at serialize and unserialize functions,
serialize generates a string from a variable and then unserialize can
give you the value of the variable back from the string.

Regards,

Jonathan

    Well, print_r() simply iterates the array and prints it.... so if
you just want the array, skip print_r() entirely and use the variable
you were passing to it.

    There's plenty of ways to parse strings into arrays, it just
depends on how you want to do it.  For one example, if you wanted to
split each word into an individual array value, you could do:

<?php
$sentence = "This is a test.";
$words = explode(' ',$sentence);
/*
Then $words would contain:
    [0] => This
    [1] => is
    [2] => a
    [3] => test.
*/
?>

POST without POSTing

I'm sure this has been covered before, but I'm not even sure how to
search in the archives for it.

I have a form that collects certain info via POST. It is re-entrant, so
when the user hits the "submit" button, it checks the input and does
whatever sanity checks it needs to. If all is okay, it must now pass
some of that info to another URL (offsite) via POST. Normally, the
information would be passed via a series of GET variables or SESSION
variables. But in this case the site the user is being directed to must
receive the information via POST.

I'm not sure how to do this. Please no exotic external libraries my
shared hosting provider doesn't include. RTFM will be fine; just tell me
which Fine Manual to Read.

Paul

    Nothing too exotic at all, Paul.  Check out cURL:

I was afraid you were going to say that, and I wasn't sure cURL was
supported on that server. But I just loaded phpinfo on that server, and
it is supported.

However, assuming it *wasn't*, I've found the following example from a
google search (thank goodness for google's "hinting" or I couldn't have
found it):

$fp = fsockopen("www.site.com", 80);
fputs($fp, "POST /script.php HTTP/1.0
Host: www.site.com
Content-Length: 7

q=proxy");

I don't know much about doing things this way. It appears that when done
this way, the "body" must be separated by a newline, just like email.
And it appears that the content-length of 7 indicates the length of the

    Yes.  Hosts are more likely to have cURL installed and available
than fsockopen() or URL-based fopen() calls, so portability is greater
with cURL.  It's also a bit faster.  Still, as you know, there's
always more than one way to skin a cute, furry, delicious little
kitten.

fsockopen() appears to be part of the standard network functions in PHP,
