making print_r use PHP_EOL

Question

My PHP_EOL is \"\\r\\n\", however, when I do print_r on an array each new line has a \"\\n\" - not a \"\\r\\n\" - placed after it.

Any idea if it\'s pos

This may not be the most elegant solution, but you could capture the print_r() output using buffer output, then use str_replace() to replace existences of \n with your PHP_EOL. In this example I've replaced it with x to show that it's working...

ob_start();

$test_array = range('A', 'Z');
print_r($test_array);

$dump = ob_get_contents();
ob_end_clean();

As pointed out by dognose, since PHP 4.3 you can return the result of print_r() into a string (more elegant):

$dump = print_r($test_array, true);

Then replace line endings:

$dump = str_replace("\n", "x" . PHP_EOL, $dump);
echo $dump;

Output:

Arrayx
(x
    [0] => Ax
    [1] => Bx
    [2] => Cx
    [3] => Dx
    [4] => Ex
    [5] => Fx
    [6] => Gx
    ... etc
    [25] => Zx
)x
