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
例
- 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>
