Bug description:On empty files, SplFileObject::fgets() returns not FALSE but
EMPTY STRING
Description:
------------
I don't know whether this is a bug or a documentation problem.
In SplFileObject::fgets documentation,
Example is shown as following:
<?php
$file = new SplFileObject("file.txt");
while (!$file->eof()) {
echo $file->fgets();
}
?>
But this should be:
<?php
$file = new SplFileObject("file.txt");
while (($buffer = $file->fgets("file.txt")) !== "") {
echo $buffer;
}
?>
I show you the test script.
Test script:
---------------
<?php
$arr = array();
$file = new SplFileObject("empty_file.txt");
while (!$file->eof()) {
$arr[] = $file->fgets();
}
var_dump($arr);
Expected result:
----------------
array(1) {
[0]=>
bool(false)
}
# Actually, this substitution should not occurr.
Actual result:
--------------
array(1) {
[0]=>
string(0) ""
}
# I think this can give us lots confusion.
