HomeBackend DevelopmentPHP Tutorial 怎么将print_r()的输出存入变量

如何将print_r()的输出存入变量
希望将多维数组转换为类似print_r()输出的格式,用了var_export()和var_dump()都是直接输出了

不止可否将输出的内容接受到某个变量,或者将数组以类似的格式转化为字符串的方法。

不胜感激。

------解决方案--------------------
print_r 和 var_export 都可以将第二个参数设为 true (默认是 false) 来使结果保存大变量中

PHP code
$a = array(1,2,3);
$r1 = print_r($a, 1);
$r2 = var_export($a, 1);

echo $r2;
echo $r1; <div class="clear">
                 
              
              
        
            </div>
