php调用有输出的函数,但是不输出,赋值到变量中。
假如有一个函数,如下:
function a(){
  echo "abc";
}
那么,每次调用a()函数的时候就会输出内容,如何实现调用后不输出,而赋值到一个变量中。

------解决方案--------------------

PHP code
<?phpfunction a(){  echo "abc";}ob_start();a();$str = ob_get_contents();ob_end_clean();echo $str;?><div class="clear">
                 
              
              
        
            </div>
Copy after login
