in_array doesn't work on class array variable

[pemodig]

Hi!
I got a problem with the in_array() function when the haystack is an class-array.

I'm only get a match with value at first position in the array.

What i'm doing wrong?
The print_r() function seems to print what I expect.

class excludeMail 
{
	var $mailadresses =  array();

function excludeMail($file = "", $file_name = "",  $file_size = "", $file_type = "")
{
	if ($file<>"none" AND $file_name != "") 
		{
			echo $file_name."<br>";
			echo $file_size."<br>";	
			echo $file_type."<br>";					
			if ($file_size > 3000000)
				{
					echo "Filen ".$file_name." är för stor. Uppladdningen har avbrutits<p>";
				}
			if ($file_type != "text/plain")
				{
					echo "Filen ".$file_name." är i fel textformat. Uppladdningen har avbrutits<p>";
				}
			if(!@copy($file, $path.$file_name))
				{
					echo "Problem med att ladda upp filen ".$file_name.". Uppladdningen avbröts!<p>";
				} 

		$filename = $path.$file_name;
		$fd = fopen($filename, "r");
		$contents = fread($fd, filesize($filename));
		fclose($fd);
		$this -> mailadresses = explode("\r", $contents);
	}
}

function checkadress($mail) 
{
	if(is_array($this -> mailadresses)) {
		print_r( $this -> mailadresses);
		if(in_array($mail ,  $this -> mailadresses)) {
				return false;
			} else {
			return true;
		}

	} else {
		return true;
	}
}
}

what datatype is $mail supposed to be? a string?

[pemodig]

Hi!
Yes the datatype of $mail is string.

are you sure it should be the otehr way around? like if its in the array, return true? think about your logic some more, and get back to me...

[pemodig]

Hi!
The logic is like i want it to be, i could have reverse it and returned true with match and false otherwise, but the problem is still the same.

I only get match on the first value in the array (e.g. first row in file). If i switch the two first rows in the file i get match on the new first value.

You'd probably have more success if you used file() to read the whole file into an array, and then use trim() on each element to get rid of the newline characters.

$this -> mailadresses = explode("\r", $contents); 

would only do what you want on Macs; other systems use different characters to delimit lines in text files.

Check your data. I've had no problem using in_array on member arrays.

<?php
class a {
  var $a = array( "no", "yes" );
  function find($string){
    if(in_array($string, $this->a)){
      echo "found";
    }
  }
}
$a = new a();
$a->find("yes");

?>

to expand upon wheat weed said...

$array = array_map('trim', file($file));
