变量初始化你如何写
变量初始化你怎么写?
数量少的变量初始化信手拈来
如果数量较多的时候就有点难受了
$a,$b,$c,$d,$e.....
写成这样
$a=0;
$b=0;
$c=0;
$d=0;
$e=0;
....
不好看,不方便,不舒服...
那么你怎么初始化?别告诉我不初始化,关闭错误提示.
------解决方案--------------------
$a=$b=$c=...=0;
$d=$e=...=array();
这样好看点了不? 哈哈 没碰到太多需要初始化的变量了
------解决方案--------------------
如果没有规律那就只能人肉了。有规律还好写。如果从数组中可以用 extract/list;
引用一段:
- PHP code
$my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse"); extract($my_array); echo "\$a = $a; \$b = $b; \$c = $c"; //输出:$a = Cat; $b = Dog; $c = Horse <br><font color="#e78608">------解决方案--------------------</font><br>我不会设计这么多变量哈哈。有几个就老老实实写几行 <br><font color="#e78608">------解决方案--------------------</font><br> php 允许不初始化变量,这表现出了 php 的灵活性、简便性<br>如果一定要初始化,倒不如<br>extract(array_flip(explode(',', 'a,b,c,d,e,f,g,h')));<br><br>$a=0;<br>$b=0;<br>$c=0;<br>$d=0;<br>$e=0;<br>.... 烦!!<br><br>$a=$b=$c=...=0;<br>$d=$e=...=array();也烦!!<br> <br><font color="#e78608">------解决方案--------------------</font><br>等哪天,php 变成编译型语言了,就不烦这个了。那又烦什么呢.... <br><font color="#e78608">------解决方案--------------------</font><br> 不仅要隔行写,而且每行还要加满注释。<br>话说做报表为啥要初始化这么多变量?共享下你的设计呗。<br>我也做过一个自定义的报表功能,选表选字段选关联选条件添加统计添加过滤搜索,好像没有类似说初始化多个变量的需要啊。 <br><font color="#e78608">------解决方案--------------------</font><br>本来人家php设计的时候,就是可以变量啥时候用啥时候定义,不知道。那位哥,把php修正成了一种类似强类型的不伦不类的东西。跟个杂种一样。太不容易了,php程序员苦逼啊 <div class="clear"> </div>
