php注释
用于描述代码功能,不会被视为php代码.
php注释分单行注释和多行注释
php单行注释使用: // 或 #
php多行注释使用:/* 中间为注释内容 */
例如:
<?php echo "This is a test"; // This is a one-line c++ style comment /* This is a multi line comment yet another line of comment */ echo "This is yet another test"; echo 'One Final Test'; # This is a one-line shell-style comment ?>
要确保不要嵌套多行注释。试图注释掉一大块代码时很容易出现该错误。
<?php /* echo "This is a test"; /* This comment will cause a problem */ */ ?>
