using "for"

[Anon]

hi everyone,
i need help on this issue,
i have an array and i would build something like this:
for ($obj in $target["a","b","c"]😉
{
if ($obj=$target["a"])
{$msg="caution";}
elsif($obj=$target["b"])
{$msg="alert";}
else {$msg="warning";}
foreach ($goal as $obj)
{
print $goal;
print $msg;
}

wich is the correct syntax?
Is there a way to code it fatest?
Thank's a lot in advance and sorry for my English!!!!!!!

For one, $obj will always equal $target["a"]. You are not setting your if, else statements correctly.

It should read:

if ($obj == $target["a"])
{your output here}

You are not testing for a comparison in your code...

[Anon]

yes it's correct, i wrote "=" instead of "==", but what about the rest? it's correct?

I don’t for sure understand what are you mean but maybe use switch function will be right instead of if function

[Anon]

i'm sure switch work better then "if-elseif-else" in this case, but my problem is not there, i need a good way to write the first "for" statement, i'm receiving an error on that line!!!
any ideas?

[mersal]

I can't understand you maybe if give me the idea which your work maybe I find the solution

OK,
I have several servers, each one run a service such as pop,smtp,http.
pop servers are pop1,pop2,pop3 ecc
http serve are web1,web2,web3 ecc
smtp server are smtp1,smtp2,smtp3 ecc
i create an array like this:
$target= array (
"smtp" => array ("1"=>"smtp1.csi",
"2"=>"smtp2.csi",
"3"=>"smtp3.csi",
)
"pop" => array ("1"=>"pop1.csi",
"2"=>"pop2.csi",
"3"=>"pop3.csi",
)
"web" => array ("1"=>"web1.csi",
"2"=>"web2.csi",
"3"=>"web3.csi",
)
);

I want to monitor services for every server on specific port with:
$fd=fsockopen($host,$port,$errno,$errstr,10);

If i use foreach three times it's easy
example:
foreach($target["smtp"] as $host){
$port="25";
$fd=fsockopen($host,$port,$errno,$errstr,10);
if (!$fd) {
$color="red";
$msg="not active";
}
else {
$color="green";
$msg="active";
fclose ($fd);}
//then i change target and port for two times, but in this way i have to use function foreach three times.
Now, what kind ok structure i need to use only one time the functio foreach?
I hope i explained good my problem?

if you have php 4.0.6
Try:
while(isset(array_search($obj,$target)))
{
your code here
}
instead of: for ($obj in $target["a","b","c"]😉

If you don't have php 4.0.6 here is a neutered version of a function I wrote a long time ago:

function findinarray($searchvalue,$array)
{
if(isset($array))
{
do{ if (current($array) == $searchvalue){ return TRUE;}}
while (next($array));
}
else { return "null"; }
}

while("null" != findinarray($obj,$target))
{
your code here
}

i have php 4.0.6 but the first statement oyu suggest doesn't work, i receive an error like this:
Parse error: parse error, expecting T_VARIABLE' or'$'' in c:\programs\apache group\apache\htdocs\testmon.php on line 61, which is the line
while(isset(array_search($obj,$target)))

[cordex]

I'm terribly sorry,
while(array_search($obj,$target))
{
// your code here
}
isset() is not needed

You will have to change the value of $obj in your code or you'll end up with an infinite loop (always fun!)

i'm not sure but array_search is not a function, i'm running apache 1.3.19 and php 4.0.6 under win2000 , i search array_search also on www.php.net but i couldn't find it!!!
