in_array not working--trouble with needle array

[RopeADope]

Hi all.

 

I've got this bit of code:

   $needles=array(`.`,`..`,`css`,`php`,`input_forms`);

   $t1=scandir($_SERVER['DOCUMENT_ROOT']);
   foreach($t1 as $t1_value){
      if(!is_dir($t1_value)){
         unset($t1[array_search($t1_value,$t1)]);
      }else{
         unset($t1[array_search($needles,$t1)]);
      }
   }

 

As you can see, I'm trying (in the else statement) to array search $t1 for everything in $needles, then unset the matches from $t1.  But its not working and I'm not sure why.  I also tried...

unset($t1[array_search(in_array($needles,$t1),$t1)]);

 

But that doesn't work either.  It only removes the "." directory from the array.  Any ideas on what's going wrong?

In your $needles array, your using backticks instead of quotes.

That was a last ditch effort sort of thing.  I've also tried single/double quotes and still no luck.

Have you tried to dump $tl or $tl_value to see what is stored?

var_dump($tl_value); // inside the else statement of course

Have you tried to debug your code and find out why it's not matching yet?

The problem is that you are using an array as your needle in the array_search() in your else statement.  It is using only the value at key 0 for this (a.k.a your '.' directory).

 

Here's a quick fix:

 

<?php

$needles=array('.','..','css','php','input_forms');
$t1=scandir($_SERVER['DOCUMENT_ROOT']);

foreach($t1 as $t1_value){
   if (!is_dir($t1_value)){
      unset($t1[array_search($t1_value,$t1)]);
   }else if (array_search($t1_value,$needles) !== false){
      unset($t1[array_search($t1_value,$t1)]);
   }
}
   
?>

 

This time, if it's a directory, it is checked against the $needles array, and if it does in fact match, then it is unset from the scandir array.
