php - 在php中将数组更改为用逗号按asc排序的字符串

Question

我有一个数组：

$array = array(
"peter",
"john",
"maria",
"bob"); 

现在我需要以某种方式将数组更改为字符串（按 asc 排序），例如：

$string_with_commas = "bob, john, maria, peter";

Answer 1

<?php

$array = array('lastname', 'email', 'phone');
sort($array)
$comma_separated = implode(",", $array);

echo $comma_separated; // email,lastname,phone

?>

Answer 2

$array = array("peter", "john", "maria", "bob"); 

sort($array);

$string_with_commas = implode(', ', $array);

Answer 3

<?php
sort($array);
echo implode(', ', $array);

sort()将修改您的阵列。如果你不想要那个，你必须复制那个数组。

<?php
$sorted_array = $array;
sort($sorted_array);

Answer 4

sort($array); //sort array in ASC order
$string = implode(', ', $array); //store as comma separated string

Answer 5

只需这样做：

$string_with_commas = implode(', ', $array);
