else that wont loop

[maxwel]

while(false!== ($file = readdir($res))) {
if(strpos(strtolower($file),$q)!== false &&!in_array($file,$exclude)) {

if (($info["extension"] == "mp3") || ($info["extension"] == "wav")) {
}else{}
}
}

the problem is that when i put an error msg in the else of the red code part it loops as much as files that are not mp3 or wave type. so how i can stop that from happening? and if i did put it outside it wont read $file variable. or even is it possible to know how to make another variable that can bring results of my search outside the while loop cuz i tried alot of things but didnt work :S

 

Thanks in advance,

Maxwel

what, exactly, are you trying to achieve?

[maxwel]

i want to simply echo an error msg without this error msg being looped

 

another question please: is it possible to get value of certain value from one server to another by php?

so you want to break() out of the loop after the first error? or you want to show the last error message?

 

your other question is too vauge to answer with aything more than "it depends".

[maxwel]

no i want to keep the loop but not to loop the error msg as its inside the loop, is that possible?

[Muddy_Funster]

if it's inside the loop, it's part of the loop. Although you could use a conditional to set the error only if it is not already set, something like

if(...
}
elseif(!isset($errorMsg)){
  $errorMsg = "Your Error Message";
}
else{
...
}

Muddy_funster is right. You can set the error message in the loop and echo the error message after the loop completes:

while(false!== ($file = readdir($res))) {
if(strpos(strtolower($file),$q)!== false &&!in_array($file,$exclude)) {

if (($info["extension"] == "mp3") || ($info["extension"] == "wav")) {
}elseif(!isset($errorMsg)){
  $errorMsg = "Your Error Message";
}
}
}// now we are out of the loop
if (isset($errorMsg)) echo $errorMsg;

That's a completely different question, I suggest you make a new thread, with a good title, and a very informative description of your problem.
