This is an issue of composer as well: https://github.com/composer/composer/issues/4628

Description:
------------
fopen() function cannot access files whose path is more than 258 characters long.


Test script:
---------------
<?php
// Generates a sample file whose path is exactly 259 characters long
$testFile = __DIR__."\\".str_repeat("a", 254 -
strlen(__DIR__)).".dat";
echo "Generating a file with a path length of ".strlen($testFile)."
characters...\r\n";
touch($testFile);

echo "Opening file... ";
if ($fp = fopen($testFile, "r")) {
  fclose($fp);
  echo "OK";
}

Expected result:
----------------
Generating a file with a path length of 259 characters...
Opening file... OK

Actual result:
--------------
Generating a file with a path length of 259 characters...
Opening file... 
Warning:
fopen(S:\Emanuele\Temp\aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.dat):
failed to open stream: Invalid argument in test.php on line 8
