Question

如何将 OPTIONS 列拆分为数组，其中数组的索引将为字符串中的数字。例如，使用此

[OPTIONS] => {0: 'phy','chem','bio'},{1: 'webtech','algo'}

将导致

Array
(
    [0] => [
        [0] => 'phy',
        [1] => 'chem',
        [2] => 'bio'
    ],
    [1] => [
        [0] => 'webtech',
        [1] => 'algo'
    ]
)

Index.php

<?php
    try {
        $pdo = new PDO('mysql:host=localhost;dbname=mydb','root','');
        $pdo->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
    } catch (PDOException $e) {
        die("Eror");
    }

    $stmt = $pdo->query("SELECT * FROM table");
    $data = $stmt->fetchAll(PDO::FETCH_OBJ);


    foreach ($data as $key) {
        echo "<pre>";
        print_r($key);
        echo "</pre>";
    }
?>

结果

stdClass Object
(
    [ID] => 1
    [FACULTY_NAME] => APPLIED SCIENCE
    [DEPT] => SLT,COMPUTER SCIENCE,FOOD TECHNOLOGY,NUD,HMT,
    [OPTIONS] => {0: 'phy','chem','bio'},{1: 'webtech','algo'}
)

不同爆炸和str_replace的组合将为您提供结果。

我同时使用爆炸和多重爆炸。
首先，我展开到不同的子数组，然后再进行多重分解，并且第一个值是键，其余的是值，然后用array_slice拆分。

$str = "{0: 'phy','chem','bio'},{1: 'webtech','algo'}";

$arr = explode("},{", str_replace("'", "", $str));
foreach($arr as $a){
    $temp = multiexplode([": ", ","], str_replace(["{", "}"], "", $a));
    $res[$temp[0]] = array_slice($temp, 1);
}


var_dump($res);

function multiexplode ($delimiters,$string) {

    $ready = str_replace($delimiters, $delimiters[0], $string);
    $launch = explode($delimiters[0], $ready);
    return  $launch;
}

$ res：

array(2) {
  [0]=>
  array(3) {
    [0]=>
    string(3) "phy"
    [1]=>
    string(4) "chem"
    [2]=>
    string(3) "bio"
  }
  [1]=>
  array(2) {
    [0]=>
    string(7) "webtech"
    [1]=>
    string(4) "algo"
  }
}
