如何从数组中检索数据

Question

是yii2的初学者。在我的程序中有一个名为Place的数组。它包含如下值：

Array
(
    [0] => Array
        (
            [0] => Aluva
            [1] => Paravoor
        )

    [1] => Array
        (
            [0] => Ernakulam
            [1] => Paravoor
        )

    [2] => Array
        (
            [0] => Aluva
            [1] => Ernakulam
        )

    [3] => Array
        (
            [0] => Kottuvally
            [1] => Paravoor
        )

)

如何从此数组中检索每个元素？

Answer 1

使用foreach？

library(alr4)
library(ggplot2)
p <- ggplot(walleye, aes(x= age)) + geom_histogram() + facet_grid(~age)
p %+% subset(walleye, age %in% 1:4)

Answer 2

示例代码 -

<?php
$data = array(
        0 => array(0=>'Aluva', 1=>'Paravoor'),
        1 => array(0=>'Ernakulam', 1=>'Paravoor'),
        2 => array(0=>'Aluva', 1=>'Ernakulam'),
        3 => array(0=>'Kottuvally', 1=>'Paravoor')
    );


foreach ($data as $key => $value) {
    foreach ($value as $key1 => $value1) {
        echo '<br>'.$value1;
    }
}

Answer 3

myScript1.py

$var = $Place[0][1]; 现在在哪里＆＃34; Paravoor＆＃34;

Answer 4

您可以使用array_walk函数

$total = [];
array_walk($sales, function($value) use(&$total) {
    foreach ($value as $key => $arr) {
        echo $arr. "<br>";
    }
});
