-----------------------
上面显示的值:057188885281-001
怎么截取-后面001 

大虾求解


回复讨论(解决方案)

$str='057188885281-001';$str=$value['haoma'];echo substr($str,stripos($str,'-')+1);

$str='057188885281-001';$str=$value['haoma'];echo substr($str,stripos($str,'-')+1);

现在是可以截取到了,但是如果有些号码没有-001 可以为空不?
----------------------
显示:
号码                   工号
057188885281-001       001
057188885282           


$str='057188885281-001';$str=$value['haoma'];echo substr($str,stripos($str,'-')+1);

现在是可以截取到了,但是如果有些号码没有-001 可以为空不?
----------------------
显示:
号码                   工号
057188885281-001       001
057188885282           

为空可以啊,有啥问题?自己试下代码不就好了

foreach ( $info as $key => $value)
     {

     }

--------------------
在循环显示出来的时候,有的是没有带工号的
--------------------------
现在的效果是:
号码                     工号
057188885281-001         001
057188885282             057188885282    

--------------------------
我想要的效果是:
   号码                     工号
057188885281-001         001
057188885282                 

$str = '057188885281-001';$str = $value['haoma'];if (stripos($str, '-') !== FALSE) {    echo substr($str, stripos($str, '-') + 1);} else {    echo $str;}

1、

echo substr('057188885281-001',-3,3);


2、
echo substr($str,-3,3);

2、

$arr = explode('-', '057188885281-001'); echo $arr[1];

也可以用 stristr...

$str = '057188885281-001';$str = $value['haoma'];if (stripos($str, '-') !== FALSE) {    echo substr($str, stripos($str, '-') + 1);} else {    echo $str;}


--------------------------------------------

页面显示的格式是:
号码                          工号
057188885281                  001         ---这是带工号的
057188885281                              -- 没带工号的
13111113086                               -- 没带工号的
-----------------------------------------------
上面是我想实现的效果

------------------------------------------------
下面是你们给我的代码显示的效果

页面显示的格式是:
号码                          工号
057188885281-001            001         ---这是带工号的
057188885281                057188885281          -- 没带工号的
13111113086                 13111113086    -- 没带工号的





谢谢大家 我搞定了
