为什么会出现乱码“Parse error: syntax error, unexpected '：' (T_STRING) in /54/883/GWMP/index.php on line 9”
<?php
$a = TRUE; //A同意
$b = TRUE; //B同意
$c = FALSE; //C反对
$d = FALSE; //D反对
//咱顺便复习下三元运算符
echo ($a and $b)?"通过":"不通过";
echo "<br />";
echo ($a or $c)?"通过"："不通过";
echo "<br />";
echo ($a xor $c xor $d)?"通过":"不通过";
echo "<br />";
echo !$c? "通过":"不通过";
echo "<br />";
echo $a && $d ? "通过":"不通过";
echo "<br />";
echo $b || $c || $d?"通过":"不通过";
?>
