Hi everyone.

I´m facing a big trouble that a don understand why is it happenin.

I´ve got an array with 1046 elements in it like this.

Here is a part of a print_r of my array.

Array ( [0] => 0001-01 [1] => 0003-01 [2] => 0140-01 [3] => 0141-01 [4] => 
0142-01 [5] => 0170-03 [6] => 0181-01 [7] => 0182-04 [8] => 0186-06 [9] => 
0186-08 [10] => 0550-01 [11] => 0720-01 [12] => 0730-01 [13] => 0740-01 [14] 
=> 0750-01 [15] => 1311-07 [16] => 1316-01 [17] => 1316-02 [18] => 1316-03 
[19] => 278980198657138 [20] => 278980198657139 [21] => 278980198657141 [22] 
=> 278980198657142...

I get some data from mysql and try to use both functions that´s in the 
subject to test if the code returned by database is in array, but it isn´t 
working.

By a for i pass by each register returned by database and print the code and 
if it´s in my array, something like this:

for($y=0; $y<$con->count;$y++){
   $con->Seek($y);
   echo $con->result['cod_loja']." - 
".(array_search($con->result['cod_loja'],$_SESSION["cod_loja"])?"Found":"Not 
found")."<br>";
  }

Here is a part of result of the code above:

0003-01 - Not found
0140-01 - Not found
0141-01 - Not found
0142-01 - Not found
0170-03 - Not found
0181-01 - Not found
0182-04 - Not found
0186-06 - Not found
0186-08 - Not found
0550-01 - Not found

Notice that the code 0003-01 is one code that is in my arrasy, but the 
function do not found it.

Could anyone help me in this, please?

Thanks a lot.
