MMMHUHU假设你 变量 $data["fimgs"] 的值是 ["a1"=>"b1","a2"=>"b2"]那么会循环两次第一次 $key 等于 "a1" $value 等于 "b1"第二次 $key 等于 "a2" $value 等于 "b2"0 0 0沧海一幻觉 遍历$data[["fimgs"] 数组 , $key 数据的键 $value 是数组的值 0 0 0...
foreach(array_expressionas$value)statement foreach(array_expressionas$key=>$value)statement 第一种格式遍历给定的 array_expression 数组。每次循环中,当前单元的值被赋给 $value 并且数组内部的指针向前移一步(因此下一次循环中将会得到下一个单元)。 第二种格式做同样的事,只是除了当前单元的值以外,键值也会...
for循环来进行带数字索引数组遍历,而foreach()可以遍历一切数组,foreach($arr as $key => $val),as就是从$arr中取值$val,然后再在循环里面打印数组的值,关联数组索引被称为键值对,list和each遍历数组,感觉麻烦,while(list($key,$val) = each($arr)){echo "{$key}:{$val}";多维数组,数组里面套数组,...
把$_POST 带入到了查询函数,然后 foreach key ,foreach 出来的 key 做了查询中的 column。防止方法一般是把数据库中的 column 查询出来,然后 in_array 判断一下 $_POST 出来的 key 是否在数据库中的 column 中。参考漏洞:云人才系统 SQL 注入,绕过 WAF wooyun-2014-060166.html参考漏洞:Cmseasy SQL ...

This can be done by specifying both the key and value in the foreach definition, like this:Example Print both the key and the value from the $members array: $members = array("Peter"=>"35", "Ben"=>"37", "Joe"=>"43"); foreach ($members as $x => $y) { echo "$x : $y ...
Once your round robin mailer has been defined, you should set this mailer as the default mailer used by your application by specifying its name as the value of the default configuration key within your application's mail configuration file:...
