PHP删除指定字符。
输出的 3,7,14,3,60, ,现在用什么方法能把最后一个","去掉,结果:3,7,14,3,60
------解决方案--------------------
变通一下
- PHP code
$d = array( 0 => array( 'a' => string 'Days_3' (length=6) 'b' => string '3 Days' (length=6) ) 1 => array( 'a' => string 'Days_7' (length=6) 'b' => string '7 Days' (length=6) ) 2 => array( 'a' => string 'Days_14' (length=7) 'b' => string '14 Days' (length=7) ) 3 => array( 'a' => string 'Days_30' (length=7) 'b' => string '30 Days' (length=7) ) 4 => array( 'a' => string 'Days_60' (length=7) 'b' => string '60 Days' (length=7) ));foreach($d as $v){ echo ltrim($v['a'],"Days_").",";}

substr($str,0,-1)或者放入数组中。再用implode连接相关文章
