How To Read One Character from a File
How To Read One Character from a File? - PHP Script Tips - Reading and Writing Files
✍: FYIcenter.com
If you have a text file, and you want to read the file one character at a time, you can use the fgetc() function. It reads the current character, moves the file pointer to the next character, and returns the character as a string. If end of the file is reached, fgetc() returns Boolean false. Here is a PHP script example on how to use fgetc():
<?php $file = fopen("/windows/system32/drivers/etc/services", "r"); $count = 0; while ( ($char=fgetc($file)) !== false ) { if ($char=="/") $count++; } fclose($file); print("Number of /: $count\n"); ?>
This script will print:
Number of /: 113
Note that rtrim() is used to remove "\n" from the returning string of fgets().
