Question

我问的是转换字符串公式的最佳方法，如JSON输入[＆＃34; num1＆＃34;，＆＃34; num2＆＃34;，＆＃34; num3＆＃34;，...]到PHP 7和JS中的数组数组应该是那样的

$tobeconverted= "[\"1\",\"2\",\"3\"]" ; // consider escape character so ["1","2","3"] 
$number= array("1", "2", "3");

Answer 1

＆＃34; JS数据＆＃34;之间的转换（JSON）和PHP可以使用json_encode和json_decode

完成

<?php
$number= array("1", "2", "3");
$json = json_encode($number);
echo $json;

# ["1","2","3"]

$array = json_decode($json);
var_dump($array);

# array(3) {
#  [0]=>
#  string(1) "1"
#  [1]=>
#  string(1) "2"
#  [2]=>
#  string(1) "3"
# }

Answer 2

var x=[32,31,30,29];
var y=JSON.stringify(x);

document.getElementById("hidden").value=y;


<input type="hidden" id="hidden">

PHP

$a=json_decode($_POST['hidden'],1);

var_dump($a);

Answer 3

这是我找到的解决方案。希望它对你有所帮助。
PHP：

<?php
    $tobeconverted= "[\"1\",\"2\",\"3\"]";
    $arraystring = substr($tobeconverted, 1, strlen($tobeconverted) - 2);
    $array = explode(",", $arraystring);
    foreach ($array as $item) {
        echo $item . '<br/>';
    }
?>

JS：

  var tobeConverted = "[\"3\",\"4\",\"5\"]";  
  var array = JSON.parse(tobeConverted);

将数字字符串转换为数组
