fgetc

(PHP 3, PHP 4, PHP 5)

fgetc -- Gets character from file pointer

Description

string fgetc ( resource handle )

Returns a string containing a single character read from the file pointed to by handle. Returns FALSE on EOF.

The file pointer must be valid, and must point to a file successfully opened by fopen() or fsockopen().

Varning

Den h�r funktionen kan returnera det booleska v�rdet FALSE, men den kan ocks� returnera ett icke-booleskt v�rde som �r likv�rdigt med FALSE, till exempel 0 eller "". V�nligen l�s sektionen om booleska datatyper f�r mer information. Anv�nd ===- operatorn f�r att testa returv�rdet fr�n den h�r funktionen.

Exempel 1. A fgetc() example

<?php
$fp
= fopen('somefile.txt', 'r');
if (!
$fp) {
    echo
'Could not open file somefile.txt';
}
while (
false !== ($char = fgetc($fp))) {
    echo
"$char\n";
}
?>

Not: Den h�r funktionen �r bin�r-s�ker.
