使用分隔符在PHP中创建JSON树视图

<?php
$data = [
    'CEO',
    'CTO,Development,QA',
    'CFO,Finance,Accounting',
    'CTO,Development,Frontend,React',
    'CTO,Development,Backend,Node.js',
    'CTO,QA,Manual',
    'CFO,Finance,Budgeting',
    'CFO,Accounting,Payroll'
];

function buildTree($data, $delimiter = ',') {
    $tree = [];
    $references = [];

    foreach ($data as $item) {
        $parts = explode($delimiter, $item);
        $node = &$tree;
        $path = [];

        foreach ($parts as $part) {
            if (!isset($node[$part])) {
                $node[$part] = [];
            }
            $path[] = $part;
            $node = &$node[$part];
            $references[$part] = &$node;
        }
    }

    return ['tree' => $tree, 'references' => $references];
}

$result = buildTree($data);
$json = json_encode($result['tree'], JSON_PRETTY_PRINT);

echo $json;
?>
