{% if
user_name == "YangQing-rong‘s username" || user_name == ‘admin‘ %}
{{10*20.043123+8*times}}
{% endif %}
以上是待切分的模板view/test1.html。
以下是lexer.php,用来测试切分效果的。
<?php use Wudimei\View\Lexer; $viewName = ‘view/test1.html‘; $c = file_get_contents(__DIR__.‘/‘ . $viewName ); $l =new Lexer(); $dt = $l->scan($viewName , $c ); print_r( $dt );
切分是1.先按{%%}和{{}}切分成文本块和代码块，2.然后再对代码块进行切分，主要切分的有 数字，运算符，字符串，名称。
以下是切分后的输出。有tokens元素的是代码块。
