The file being scanned is used as a parameter to the fgetc() function and returns a string containing one character from the file, which is used as a parameter.Syntax:
 fgetc ($file)
Parameters:The fgetc() function in PHP takes only one parameter, $file. It specifies the file from which to extract the symbol.Return value:returns a string containing one character from the file, which is used as a parameter.Errors and Exceptions :
  • This function is not optimized for large files as it reads one character at a time and a long file can take a long time to fully read.
  • The buffer must be cleared if fgetc() is used multiple times.
  • The fgetc() function returns a Boolean False, but it often happens that it returns a non-boolean value that evaluates to False.
