Using PHP fgetc() to Read Characters from a File

Syntax

mixed fgetc ( resource $handle )

Parameter Description

handle

: required. File pointer resource specifying the file to read.

Return Value

If successful, returns the read character; if the end of file is reached, returns FALSE.

Notes

Before calling fgetc(), you must open the file with fopen() and pass the returned handle to fgetc(). After reading all characters, close the file with fclose().

Usage Example

$handle = fopen("file.txt", "r"); // open file
if ($handle) {
    while (($char = fgetc($handle)) !== false) { // read each character
        echo $char;
    }
    fclose($handle); // close file
}

In this example, fopen() opens "file.txt" and returns a file handle stored in $handle. A while loop with fgetc() reads characters one by one until false indicates EOF, and fclose() closes the file.

Note that fgetc() reads only a single character at a time; to read an entire line or the whole file you can use fgets() or file_get_contents().

Summary

fgetc()

is a PHP function for reading a single character from a file. It requires the file to be opened with fopen() and closed with fclose(). For larger reads, consider using fgets() or file_get_contents().
