<pre>
<?php
$d = array(
"ap" => "php",
"db" => "sql");
$results = print_r($d, true);
echo "hi/n";
echo $results;
echo "$d["ap"]";
?>
</pre>
为什么会报错呢？先记下来
Parse error: parse error, unexpected '"', expecting T_STRING or T_VARIABLE or T_NUM_STRING in d:/usr/www/html/1.php on line 19
<?php
echo (3 == 2);
echo (2 == 2);
?>
为什么只输出 １，而没有 ０ 呢？
