PHP | fgetc( ) Function
The fgetc() function in PHP is an inbuilt function which is used to return a single character from an open file. It is used to get a character from a given file pointer.
The file to be checked is used as a parameter to the fgetc() function and it returns a string containing a single character from the file which is used as a parameter.
Syntax:
fgetc($file)
Parameters: The fgetc() function in PHP accepts only one parameter $file. It specifies the file from which character is needed to be extracted.
Return Value: It returns a string containing a single character from the file which is used as a parameter.
Errors And Exception:
- The function is not optimised for large files since it reads a single character at a time and it may take a lot of time to completely read a long file.
- The buffer must be cleared if the fgetc() function is used multiple times.
- The fgetc() function returns Boolean False but many times it happens that it returns a non-Boolean value which evaluates to False.
