Re[2]: [PHP] is it possible to communicate javascript and php?
I've used the tag in Internet Exploder to talk to the server via
javascript. It may be possible using a regular frame also. Here's the low
down on how I did it.
1.) Some onclick, onchange ... action calls a javascript function that looks
like this
function getData() {
document.all.hidden_frame.src =
"databaseactions.php?getmesomedata=something";
}
2.) The output of databaseactions.php would look like
var contacts = new Array("Jeff Boyer","555-555-);
Put something here for debugging
The frame is hidden (width and height set to 0) so the client does not see
the output.
3.) A function on the main page called loadselectbox gets the array of data
returned from the server. You need to rawurlencode the data elements in the
array or javascript will complain.

[PHP] exec() bug?
Hi,
Can someone confirm this behavior on their system. I've tried it on 4.0.2
and 4.03pl1, both on Linux boxes, both with the same results.
echo "One Character: " . exec("echo 't'",$tmp) . "\n";
echo "One Character: " . $tmp[0] . "\n";
echo "Two Characters: " . exec("echo 'te'",$tmp) . "\n";
My output is:
One Character:
One Character: t
Two Characters: te
It seems if the output of exec is one character it gets discarded somewhere.
The ouput is correct in the array argument, but the "last line of output" is
not returned by the function if the length of the "last line of output" is
1.
Thanks,
Dustin

Put the story in an array and grab the first x elements? Say you want 50
words you would do:
$num_of_words = 50;
$story_array = explode(" ", $story, $num_of_words);
$story_preview = implode(" ", array_pop($story));
Assuming all words are seperated by a space.

RE: [PHP] Strange problem
There are FTP functions if it's an FTP download. You could also use socket
functions to create the request if it's HTTP. Check your system for the
utility called wget, you could exec() wget to retrieve the file also.

RE: [PHP] Problem with a regex!
Zack,
Your not going to find {title} when $var = "TITLE". Everything PHP is case
sensitive. Also $string is not changed if there are matches, ereg_replace
returns the modified string.
