最近用PhpSpreadsheet导出数据的时候发现，包含某一数据的时候总是报错，报错信息如下:

PhpOffice\PhpSpreadsheet\Calculation\Exception: 订单信息!F278 -> Uninitialized string offset: 1 in /vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Cell/Cell.php:270
Stack trace:

看信息大概是F列278行数据有问题，我就上网查了查，看见有人也遇见了这个问题，说大致是数据中有以=号开头的字符了，可能是出发了execl的函数啥的，导致参数不足，导致的错，我也是用其他字符吧这个=号替换掉就号了，希望能帮助到也遇见问题的你。
