Arrays are a powerful tool.
Once you get the hang of it, you can do almost anything.
Notice that some of them have named keys.
Anyway, I remember when I first started using arrays, especially with
named keys, and the world of possibilities
that they opened up. So I thought I would share this...
Hope it helps.
(then find a good tutorial/book and use your imagination...)
glenn
$myarray[1][0] = 'somekey';
$myarray[1][] = '1234';
$myarray[1][] = '5678';
$myarray[1][] = '9101112';
print "example a\n";
print_r($myarray);
print "example b\n";
print_r($myarray[1][1]);
print "\n";
// or
$myarray = array(
'somekey' => array()
);
$myarray['somekey'][] = '1234';
$myarray['somekey'][] = '5678';
$myarray['somekey'][] = '910112';
print "example c\n";
print_r($myarray['somekey']);
print "example d\n";
print_r($myarray['somekey'][1]);
print "\n";
//or
$myarray = array(
'somekey' => array(
'someotherkey' => array(),
'anotherkey' => array()
)
);
$myarray['somekey']['someotherkey'][] = '1234';
$myarray['somekey']['someotherkey'][] = '5678';
$myarray['somekey']['someotherkey'][] = '910112';
$myarray['somekey']['anotherkey'][] = 'aaaa';
$myarray['somekey']['anotherkey'][] = 'bbbb';
$myarray['somekey']['anotherkey'][] = 'cccc';
print "example e\n";
print_r($myarray['somekey']);
print "example f\n";
print_r($myarray['somekey']['someotherkey']);
print "example g\n";
print_r($myarray['somekey']['anotherkey']);
Output from the above code is;
example a
Array
(
[1] => Array
(
[0] => somekey
[1] => 1234
[2] => 5678
[3] => 9101112
)
)
example b
1234
example c
Array
(
[0] => 1234
[1] => 5678
[2] => 910112
)
example d
5678
example e
Array
(
[someotherkey] => Array
(
[0] => 1234
[1] => 5678
[2] => 910112
)
[anotherkey] => Array
(
[0] => aaaa
[1] => bbbb
[2] => cccc
)
)
example f
Array
(
[0] => 1234
[1] => 5678
[2] => 910112
)
example g
Array
(
[0] => aaaa
[1] => bbbb
[2] => cccc
)

Okay, here's one of the places I don't really get and can use some
help on. On my text processing script I'm going to slurp up host
names. They come in as the first, counting from 0, element. I can
explode and create the array, which gives me a string:
$hostname[1] = somehost.example.com
I can safely get rid of the ".example.com" bit, leaving $hostname[1]
as "somehost". What I need to understand is how to take $hostname[1]
and make it an array in it's own right so I can assign it a list of
numbers.
For example, my text file looks something like this:
Bug ID: 1234
Affected Machines:
somehost1
somehost2.example.com
somehostwehavenotseeninyears.example.com
Bug ID: 3456
Affected Machines:
somehost1
somehostwehanvenotseeninyears.example.com
At the end I need to print out something like this:
somehost1: 1234, 3456
somehost2: 1234
somehostwehavenotseeninyears: 1234 3456
Recommendations for a neophyte PHP'r?
Thanks!
