Example #1 $GLOBALS 范例
<?php
function test() {
$foo = "local variable";
echo ‘$foo in global scope: ‘ . $GLOBALS["foo"] . "\n";
echo ‘$foo in current scope: ‘ . $foo . "\n";
}
$foo = "Example content";
test();
?>以上例程的输出类似于：
$foo in global scope: Example content $foo in current scope: local variable
