未修改前，excel活动sheet转为json数据，运行
$sheetData = $sheet->toArray(null, true, true, true);
echo json_encode($sheetData);
返回的数据格式是：
{"1":{"A":"id","B":"c_ddid","C":"c_khid","D":"c_gyid","E":"c_dgrq","F":"c_dhrq","G":"c_fhrq","H":"c_yhs","I":"c_yhf","J":"c_hzmc","K":"c_hzdz","L":"c_hzcs","M":"c_hzdq","N":"\u8d27\u4e3b\u90ae\u653f\u7f16\u7801","O":"c_hzgj"},"2":{"A":9,"B":10256,"C":"WELLI","D":3,"E":"1996\/7\/15","F":"1996\/8\/12","G":"1996\/7\/17","H":2,"I":13.97,"J":"\u4f55","K":"\u5c71\u5927\u5317\u8def237\u53f7","L":"\u6d4e\u5357","M":"\u534e\u4e1c","N":873763,"O":"\u4e2d\u56fd"},"3":{"A":10,"B":10257,"C":"HILAA","D":4,"E":"1996\/7\/16","F":"1996\/8\/13","G":"1996\/7\/22","H":3,"I":81.91,"J":"\u738b","K":"\u6e05\u534e\u8def78\u53f7","L":"\u4e0a\u6d77","M":"\u534e\u4e1c","N":502234,"O":"\u4e2d\u56fd"},"4":{"A":11,"B":10258,"C":"ERNSH","D":1,"E":"1996\/7\/17","F":"1996\/8\/14","G":"1996\/7\/23","H":1,"I":140.51,"J":"\u738b\u5148\u751f","K":"\u7ecf\u4e09\u7eac\u56db\u8def48\u53f7","L":"\u6d4e\u5357","M":"\u534e\u4e1c","N":801009,"O":"\u4e2d\u56fd"},"5":{"A":12,"B":10259,"C":"CENTC","D":4,"E":"1996\/7\/18","F":"1996\/8\/15","G":"1996\/7\/25","H":3,"I":3.25,"J":"\u6797\u5c0f\u59d0","K":"\u9752\u5e74\u897f\u8def\u7532245\u53f7","L":"\u4e0a\u6d77","M":"\u534e\u4e1c","N":705022,"O":"\u4e2d\u56fd"}
我需要的是第一行作为字段名。修改后，运行
// 注意取数从第二行开始

echo json_encode($sheetData);

下面是修改后的函数内容。
/**
* Create array from a range of cells.
*
* @param string $pRange Range of cells (i.e. "A1:B10"), or just one cell (i.e. "A1")
* @param mixed $nullValue Value returned in the array entry if a cell doesn't exist
* @param bool $calculateFormulas Should formulas be calculated?
* @param bool $formatData Should formatting be applied to cell values?
* @param bool $returnCellRef False - Return a simple array of rows and columns indexed by number counting from zero
* True - Return rows and columns indexed by their actual row and column IDs
