我查看了堆栈溢出讨论Can't access global variable inside function。
它解决了这个问题。但我无法让代码工作。我试图从函数 ConvertCsvFile 中访问 $batch_fl_str 和 $batch_str 但我无法访问这两个变量。
有什么建议么?这是我的代码:
$today = date(ymd);
$curr_time = date(Hi);
$local_time = localtime();
$curr_min = str_pad($local_time[1], 2, '0', STR_PAD_LEFT);
$curr_hr = str_pad($local_time[2], 2, '0', STR_PAD_LEFT);
$batch_fl_str = "-" . $today . "-" . $curr_hr . $curr_min;
$batch_str = $today . "-" . $curr_hr . $curr_min ;
function ConvertCsvFile($input_path, $input_file, $input_hist_path, $hdl_output_fl, $hdl_out_hist_fl) {
// Define static variable
global $batch_fl_str;
global $batch_str;
static $fl_no = 0; //NOTE: static variable
$fl_no++;
$fl_no_str = str_pad($fl_no, 3, 0, STR_PAD_LEFT);
$batch_fl_id = $batch_fl_str . "-" . $fl_no_str . "." ;
$batch_id = $batch_str . "-" . $fl_no_str . "-";
echo "Batch fl str = $batch_fl_str \n";
echo "Batch str = $batch_str \n";
echo "Batch file id = $batch_fl_id \n";
echo "Batch id = $batch_id \n";
}
运行上述程序时,我收到以下输出:
Converting the file: DOC#9553814.CSV
Batch fl str = -130511-0316
Batch str = 130511-0316
Batch fl str =
Batch str =
Batch file id = -001.
Batch id = -001-
