php ForEACh输出数组

输出<?php$arr = [1, 2, 3, 4, 5, 6, 7, 8];foreach ($arr as $k => $v) { echo $arr[$k] . " ";}或者直接 echo $v . " ";

你想要这样:foreach ($arr2 as $key){$i=rand(0,$c);echo $arr[$i]+$key->alias;}

foreach($arr as $e){echo $e[0];}字符串的【0】即是第一个字符

第二个foreach是不必要的,直接用$product['products_options_values_name']. 赞同

以下是编写json数据转换成数组时写foreach嵌套循环输出的代码: $arr = (array) json_decode($json,true); foreach($arr as $arrvalue) { foreach($arrvalue as $key=>$value) { echo "[$key] = $value "; } }?>

foreach($arr as $val){var_dump($val)}

foreach 语法结构提供了遍历数组的简单方式.foreach 仅能够来应用于数组和对象,如果尝试应用于其他数据类型的变量,或自者未初始化的变量将发出错误信息.有两种语法:foreach (array_expression as $value) statementforeach (array_

$a=array("h1","h2","h3");$b=array("c1","c2","c3");for($a as $key => $value){ echo $value . $b[$key];}希望能够帮到你$a=array("h1","h2","h3");$b=array("c1","c2","c3");for($a as $key => $value){ echo $value . $b[$key];}

//定义一个string类型的一维数组 string[] names=new string[5];//为数组赋值 for (int i = 0; i names[i]=integer.tostring(i); }//使用foreach遍历数组 int index=0; for (string name : names) { system.out.println("第"+index+"元素是:"+name);

foreach($ceshi as $name => $info){ foreach($info as $key => $val){ echo $info[0]; }}一般说来 你最好构造数据的时候 弄个下标吧 别这样用到自增的$ceshi[]=array("name"=>"zhangsan","area"=>"wangwu");这样最好 这样就可以foreach($ceshi as $name => $info){ foreach($info as $key => $val){ echo $info['name']; }}
