With a more reliable test script:

# cat t.php
<?php
$str = "0";
var_dump(substr($str, 0, 1));
var_dump(substr($str, 1, 1));
var_dump(substr($str, 5, 1));
?>

# php t.php
string(1) "0"
bool(false)
bool(false)

No bug here.

Description:
------------
substr() returns "0" for any offset on the string "0" using the length
1.

This causes an infinite loop if you are checking for leading zeros in
your string using substr().

Reproduce code:
---------------
$str = "0";

print (substr($str, 0, 1) == "0");
print (substr($str, 1, 1) == "0");

print (substr($str, 5, 1) == "0");

// only the first line should evaluate to true

Expected result:
----------------
111
