array

[Piotr Wolski]

i've got numbers written in file like that:

0.005465
0.004564
....

I want to read them into an array and have the same effect like:
$arr=array(0.005465,0.004564,..)

Do you know how to o it?

i tried something like that:

$file_name = "file_name";
$fp=fopen($file_name,"r");
$arr=implode(' ',file($file_name));
$arr2=explode(' ',$arr);

and wanted that an arr2 to be my array..

but it has no result...

You're using 2 methods here to do "the same thing". I'd suggest reading
about the file() function on php.net =)
$arr = file($file_name);
That's it! $arr is now your array as you're requiring. To test this, try:
<?php
$arr = file($file_name);
var_dump($arr);
?>
HTH =)

Since file() returns elements with newline character attached, you might
want to do this:

$arr = array_map('floatval', $file_name);

thanks, it finally worked, however you made mistake, it should be:

$arr=array_map('floatval',$arr);
