更改陣列與逗號字符串命令在PHP

Question

ASC我有一個數組：

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

現在我莫名其妙地需要將數組改變爲一個字符串（有序ASC），如：

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

Answer 1

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

sort()會修改你的數組。如果你不想這樣做，你必須複製該數組。

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

Answer 2

<?php 

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

echo $comma_separated; // email,lastname,phone 

?>

Answer 3

只是這樣做：

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

Answer 4

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

Answer 5

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

sort($array); 

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