最近我从thinkphp的‘RUNTIME_ALLINONE'借鉴到经验:不怕缓存多,就怕调用乱,索性将所有常用的文件全部合并成一个文件,岂不美哉。。。
复制代码 代码如下:
function strip_whitespace($content) {
    $stripStr = '';
    //分析php源码
    $tokens =   token_get_all ($content);
    $last_space = false;
    for ($i = 0, $j = count ($tokens); $i         if (is_string ($tokens[$i])){
            $last_space = false;
            $stripStr .= $tokens[$i];
        }
        else{
            switch ($tokens[$i][0]){
                //过滤各种PHP注释
                case T_COMMENT:
                case T_DOC_COMMENT:
                    break;
                //过滤空格
                case T_WHITESPACE:
                    if (!$last_space){
                        $stripStr .= ' ';
                        $last_space = true;
                    }
                    break;
                default:
                    $last_space = false;
                    $stripStr .= $tokens[$i][1];
            }
        }
    }
    return $stripStr;
}

该自定义函数有效解决了php_strip_whitespace系统内置去注释空格函数不能正确理解使用方法
复制代码 代码如下:
$str = strip_whitespace('
前面一定要拼接这个,我也搞不懂,不拼接的话执行生成的结果是错误的结果
php_strip_whitespace
string php_strip_whitespace (string$filename )
如果仅仅是单文件并且没有heredoc的话,还是建议使用快捷的php_strip_whitespace函数
