$str = '(function(){XQScript_0({"dataType":1,"transfer":false,"dataComplete":true,
    "isSameCity":false,"count":18,"arriCity":"新化","deptCity":"怀化","arriCity_py":"xinhua",
    "ticketInfo":{"K9058/K9055":[{"tl":112,"type":"硬座","pr":"38"},{"tl":90,"type":"硬卧上","pr":"84"},
    {"tl":90,"type":"硬卧中","pr":"89"},{"tl":90,"type":"硬卧下","pr":"92"},';
preg_match('/"ticketInfo":\{"([^"]+)/i', $str, $matches);
echo $matches[1];
/**
输出结果：
