拆分字符串并在php中形成一个新字符串

Question

如何将表单中的字符串“A，B，C，D”拆分为php中的新字符串“A B C D”？

非常感谢！ explode将形成一个数组，str_split需要长度。

Answer 1

echo implode(" ", explode("," , "A,B,C,D"));

Answer 2

str_replace(',', ' ', $str)

或

join(' ', explode(',', $str))

Answer 3

您可以使用str_replace(",", " ", "A,B,C,D");

Answer 4

<?php

$string = 'A,B,C,D';
$split  = explode(',',$string);  //this will give an array 

$newString = implode(' ',$split); // array mixed with character to form a string /

?>
