| | | | | | | | | | | |
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.
  • The programs below illustrate the fgetc() function.Program 1 : In the program below, a file named gfg.txt contains the following text. This is the first line.
    This is the second line.
    This is the third line.
    // the file is opened using the fopen() function $my_file = fopen ( "gfg.txt" , "rw" );
    // Prints one character from
    // pointer to open file echo fgetc ( $my_file );
    // file is closed with fclose() fclose ( $my_file );
    ?>
    Output:
    T
    Program 2 : In the program below, the file named gfg.txt contains the following text. This is the first line.
    This is the second line.
    This is the third line.
    // the file is opened using the fopen() function $my_file = fopen ( " gfg.txt " , " rw " );
    // prints one character at a time // until end of file is reached while ( ! feof ( $my_file )) { echo fgetc ( $my_file ); }
    // the file is closed using the fclose() function fclose ( $my_file ); ?>
