The following code:
<?php
function varToString($var) {
$allInternalFunctions = array_filter($allInternalFunctions, function($func) {
});
}
class Test {
public string $prop {
set => strtoupper($value);
}
}
$test = new Test();
var_dump($test);
$script1_dataflow = $test;
define("MAX_64Bit", 9223372036854775807);
define("MAX_32Bit", 2147483647);
$otherVals = array(0, 1, -1, 7, 9, 65, -44, MAX_32Bit, MAX_64Bit);
foreach ($script1_dataflow as $longVal) {
}
$GLOBALS[array_rand($GLOBALS)];Resulted in this output:
