Bug #23298 Floating point data loss in serialize() (and sessions)
This bug seems to be not fixed!
Script:
<?php
ini_set("precision", 32);
$var = 1.4285714285714286476;
var_dump($var);
$foo = serialize($var);
echo ' ', $foo, "\n";
$x = unserialize($foo);
var_dump($x);
var_dump($x === $var);
ini_set("precision", 12);
$var = 1.4285714285714286476;
var_dump($var);
$foo = serialize($var);
echo ' ', $foo, "\n";
$x = unserialize($foo);
var_dump($x);
var_dump($x === $var);
?>
output:
float(000ý)
d:000ý;
bool(false)
bool(false)
float(000ý)
d:000ý; n
bool(false)
bool(false)
