Hello everyone,
I have a very long array. I want to pull all the data from the array

$myarray = array('0'='me', '1'='you','2'='her','3'='him','4'='them',
'5'='us');
Yes I know the array above it small it's an example, mine has over 150
positions.
$foundyou = array_search('you', $myarray);
$foundthem = array_search('them', $myarray);
Now I want to take all the array positions from $foundyou to $foundthem and
put their values into a variable;
For the life of me I can't remember how I did it.
I DO NOT want to foreach over the array positions that would be
counterproductive.
Well, depends on exactly what you mean by and put their values into a
variable. Do you mean concatenate all the values into one single
flat variable. Or do you mean to make a subset array of the values
between your two points you found?
First, check out array_slice.
Second, look at join
?php
$myarray = array(
'0'='me',
'1'='you',
'2'='her',
'3'='him',
'4'='them',
'5'='us',
);
$s_pos = array_search('you', $myarray);
$f_pos = array_search('them', $myarray);
# Calculate the length, it is needed by array_slice()
$length = ($f_pos - $s_pos);
$subset_array = array_slice($myarray, $s_pos, $length);
print_r($subset_array);
$all_values = join(', ', $subset_array);
echo $all_values;
?
Obviously, you need to add in some error checking. But that should get
you started.

Length was my problem the whole time.
Thank you very much.

Hi,
I was using gethostbyname up until recently but switched to Net_DNS2
due to lack of support for a timeout. Now I discovered some worrying
behaviour and hope someone here get shed some light onto it.
I am running PHP inside an Apache 2 installation as module and noticed
that once I call gethostbyname it appears to block all other
concurrent independent requests to PHP pages until the call returned.
I do seem to remember that there were some reentrant issues with the
native gethostbyname function but I wouldnt assume there is some kind
of global lock on it blocking the entire runtime.
What is even more worrying is that Net_DNS2 appears to show the same
behaviour, even though from my understanding it is supposed to work
completely independent with its own streams/sockets.
Of course this behaviour only shows with a domain with non-responding
name

Of course this behaviour only shows with a domain with non-responding

it easily with
?php
echo gethostbyname('vuav.com');
// OR ..
require('Net/DNS2.php');
$dr=new Net_DNS2_Resolver(['nameservers'=['8.8.8.8']]);
$ans=$dr-query('vuav.com');
echo $ans-answer[0]-address;
?
Could it have to do something with a configuration setting or might I
be onto something?
Thanks a lot!

My apologies, it looks like it was a false alarm and the blocking
actually comes from PHP's session manager.
Sorry,

[PHP] redirect a shell command to stdout in real time
Hi All, I want to redirect the stdout of an executing shell command to stdout of php called by browser The command some stream like command like ffmpeg -i rtmp://192. - rtmpdump -v -r rtmp://192 -a app -y stream -o - so its live video, and the execution not stops, till the user navigate out with browser. What I want loading this php from web based, to print the live video content to the stdout of php, So the call result of php is video and starts almost with header(Content-Type: video/x-flv); Hope there's solution in php Thanks Zocs
Re: [PHP] redirect a shell command to stdout in real time
You can use pipe to run the command and capture the stdout. Then dump it with proper header to browser. Note, If the external command (specially video encoding) takes long time you should probably use cron for this and maintain a queue. I recommend you apply some sorts of caching also. -- Shiplu.Mokadd.im ImgSign.com | A dynamic signature machine Innovation distinguishes between follower and leader

Re: RES: [PHP] fets() escaping some characters
Or, if that string is the only thing you want to output and nothing else
you will set the correct content type for your output by putting
header('Content-Type: text/plain; charset=utf-8');
at the beginning of your script
