php数组转字符串

$array=["php","Java","web"];

$result=implode(",",$array);

<?php

// PHP数组转字符串的方法

// 方法一:implode(glue, pieces)

$arr = ['Lucy','Mike','Jery','Haly'];

$str = implode(',', $arr);

// var_dump($str);

//方法二，利用循环遍历数组元素拼接成字符串

$arr1 = ['Lucy','Mike','Jery','Haly'];

$str1 = '';

foreach ($arr1 as $key => $value)

{

$str1 .=','.$value;

}

var_dump($str1);

<?php

//数组转字符串 org.apache.commons.lang3.StringUtils

String str3 = StringUtils.join(arr); // 数组转字符串,其实使用的也是遍历

System.out.println(str3); // 012345

String str4 = StringUtils.join(arr, ","); // 数组转字符串(逗号分隔)(推荐)

System.out.println(str4); // 0,1,2,3,4,5
