[PHP] Muti-Dimensional Array Help Please
hello all,
I have some text files in a directory that contain newline delimited IP
addresses. Here is what i would like to do with them, and what i have
achieved so far:
I read the files into a multi-dimensional array like: (pseudo code)
array(IP_blocks) = (
File_number[1] = array('ip1', 'ip2', 'ip3')
File_number[2] = array('ip1', 'ip2', 'ip3')
File_number[3] = array('ip1', 'ip2', 'ip3')
)
the ip files have variable numbers of ips, some have 5 ips, some 40
etc..
What i want to do is to run a loop through the whole thing doing a task
on each IP address. Easy so far right? - Well, where im stuck is that i
want to operate on them like this:
do_stuff(File_number[1][ip1])
do_stuff(File_number[2][ip1])
do_stuff(File_number[3][ip1])
do_stuff(File_number[1][ip2])
do_stuff(File_number[2][ip2])
do_stuff(File_number[3][ip2])
I cant even get that far LoL! but then there is the problem of what
happens when there is no IP left in an array? (its a short file of
ips..)? - I need to start that particular array back at the beggining
but continue the cycle (it doesnt matter that an ip is worked on more
than once..)
Here is the *actual* code I have so far:
##CODE
?php
/*
* Open the proxies dir and read all of the
* ips contained within each file into a mutidimensional
* array ($machines)
*/
$dir = dir('proxies');
while(FALSE !== ($file = $dir-read())) {
if($file != '.' $file != '..') {
$machines[$file] = file($dir-path . '/' .$file);
}
}
$dir-close();
foreach($machines as $machineId = $ips) {
// do stuff here
}
###END CODE
Im not really expecting anyone to be able to do my work for me but some
*guidance* regardig how to tackle this problem would be magnificent...
Thankyou..

It looks like you're hading in the right direction. You've grabbed an array
of each file. Then cycle through that array and read data from each file.
The fread function will allow you to pull data from each file line by line,
so you can store each line in an array. Using your idea of pseudo-code:
$data = array();
$i = 1;
foreach ( file ) {
$n = 1;
fp = fopen
while ($line = fread() ){
$data[$i][$n] = $line;
}
}
foreach ($data as $key = $line ) {
foreach ($line as $line_number = $ip) {
// do stuff
}
}

hehe, not sure i get it but im playing with it ;-) i need to see code in
action for my head to understand it. I did have one rather good though
though (i think): If i can create an array with all of the ips in order
like this
123.123.123.1 // 1st IP from machine 1
123.123.123.2 // 1st IP from machine 2
123.123.123.3 // 1st IP from machine 3
123.123.123.4 // 2nd IP from machine 1
123.123.123.5 // 2nd IP from machine 2
123.123.123.4 // 2nd IP from machine 3
etc...
then i would have *exactly* what the application needs. Does that make
the problem any easier?
