Php Str_更换未完全更换

我有以下代码：

<?php
$str ='[ "spiderman", "xmen", "barbie", "avengers" ]';

$array= str_replace("[", "",$str);
$array= str_replace("]", "",$str);

$array =explode(',',$array);


print_r($array);

而是它的输出

Array
(
    [0] => [ "spiderman"
    [1] =>  "xmen"
    [2] =>  "barbie"
    [3] =>  "avengers" 
)

为什么它没有完全替换

[

的所有实例？ 我怎样才能做好呢？

这是一种

json

格式。不要使用

str\u replace

和

explode

对其进行解码。您可以使用

json\u decode

进行解析

$str ='[ "spiderman", "xmen", "barbie", "avengers" ]';
$arr = json_decode($str);

echo "<pre>";
print_r( $arr );
echo "</pre>";

您的字符串是json，但代码的正确形式是：

Array (
    [0] =>  "spiderman"
    [1] =>  "xmen"
    [2] =>  "barbie"
    [3] =>  "avengers"

)

这看起来与Javascript无关-请适当标记您的问题

Array
(
    [0] => spiderman
    [1] => xmen
    [2] => barbie
    [3] => avengers
)

<?php

$str ='[ "spiderman", "xmen", "barbie", "avengers" ]';

$array= str_replace("[", "",$str);
$array= str_replace("]", "",$array);

$array =explode(',',$array);


print_r($array);

Array (
    [0] =>  "spiderman"
    [1] =>  "xmen"
    [2] =>  "barbie"
    [3] =>  "avengers"

)
