[chiPHPug-discuss] troublesome PHP behavior

[Arlo L. <ar...@ar...>]

Hi folks,

Consider the following PHP code, which explodes an empty string:

    $string = "";
    $array = explode("|", $string);
    print_r($array);
    print "Length: ".count($array);

I would expect this to output an empty array:

    Array ( ) Length: 0

But it actually outputs:

    Array ( [0] => ) Length: 1

Does anyone else find this odd? It has bitten me a few times lately, when I
test the existence of data with a count(), or try to process data with a FOR
loop. I end up writing this a lot to get the expected results:

    $array = ($string) ? explode(",", $string) : array() ;

I was considering logging a bug report but wondered what your thoughts were.

Cheers,
-Arlo
