a replacement for unserialize that returns whether it worked and populates the unserialized variable
by reference:
<?php
function funserialize($serialized, &$into) {
static $sfalse;
if ($sfalse === null)
$sfalse = serialize(false);
$into = @unserialize($serialized);
return $into !== false || rtrim($serialized) === $sfalse;//whitespace at end of serialized var is
ignored by PHP
}
$s_foo = 'b:0;';
var_dump(funserialize($s_foo, $foo), $foo);
$s_bar = 'bar';
var_dump(funserialize($s_bar, $bar), $bar);
$s_foo = 'a:0:{};';
var_dump(funserialize($s_foo, $foo), $foo);
?>
gives:
bool(true)
bool(false)
bool(false)
bool(false)
bool(true)
array(0) {
}
