Help with an error

[Javis]

alright I'm new to php so im trying to learn some stuff and ive already done most of the basics. Im following a tut to build my first web site and when i debug my file i get this error

 

Fatal error: Cannot redeclare hash_file() on line 180

 

the code on line 180 looks like this

 function hash_file ($strFilename) {
    $n = 0;
    for ($posFilename = strlen($strFilename) -1; $posFilename >= 0; $posFilename-- ) {
      $n *= 2;
      if ($n & 4096) { $n |= 1; }
      $n ^= (ord($strFilename[$posFilename])*11);
      $n &= 4095;
    }
    return sprintf ("%02o/%02o", ($n/64) & 63 , $n&63);
  }

 

any one know what i should do? thanks in advanced

PHP 5 already has a function called hash_file

[trq]

There is already a function built into php5 and above called hash_file. Rename your function to something else.

thorpe got an axample or you mean like any name? im extremely new to this stuff

[rhodesa]

I'm not familiar with the function, but it looks to do the same thing as PHPs version. My guess would be that the function was added so it would work on PHP4. Add an if around it to test it's existence:

 

if(!function_exists('hash_file')){
function hash_file ($strFilename) {
    $n = 0;
    for ($posFilename = strlen($strFilename) -1; $posFilename >= 0; $posFilename-- ) {
      $n *= 2;
      if ($n & 4096) { $n |= 1; }
      $n ^= (ord($strFilename[$posFilename])*11);
      $n &= 4095;
    }
    return sprintf ("%02o/%02o", ($n/64) & 63 , $n&63);
  }
}

Any name will do. Just remember, when you call the function you'll need to use the same name. In fact you can probably proceed without the function at all and just use the newer built in hash_file function in its place.

lol i keep missing the reply button.

 

any ways ill rename it something random.

[Javis]

got a new problem went through and fixed a few others but i dont know what to do with this one

 

Call to a member function query() on a non-object on line 20

 

lines 19-22 look like the following

$sSQL="Select * from ".$pho_main." where parent=$num order by name";
  $q->query($DB, $sSQL);
  $rec=(object)$q->getrow();
  if($q->numrows()==0){

 

any suggestions

[trq]

Where is $q defined?

[Javis]

your asking for this right? if not sorry

    $rec=(object)$q->getrow();

[rhodesa]

No, on this line:

$q->query($DB, $sSQL);

You access the variable $q. Where is $q set?

[Javis]

umm fixed that one will post back if i have any more errors that i need help with
