But, when run php run.php string_here on command line windows then error

Not sure which editor you are using but it appears to be entering invalid characters at the start of the file. Some people say changing the encoding of the file works however that last time i had this issue it didn’t work for me. I would recommend downloading notepad++ (its free) and then editing the file and re-saving with that program.

Edit: I tend to use ANSI for my encoding (since its the default selected in notepad anyway) without any issues. Given the size of your file you could just retype it in notepad and save with ANSI (Do not open in notepad and re-save as it may not show the byte mark for you to delete it)
