I know PHP is usually used for web development, where there is no standard input, but PHP claims to be usable as a general-purpose scripting language, if you do follow it's funky web-based conventions. I know that PHP prints to stdout
(or whatever you want to call it) with print
and echo
, which is simple enough, but I'm wondering how a PHP script might get input from stdin
(specifically with fgetc()
, but any input function is good), or is this even possible?
It is possible to read the stdin
by creating a file handle to php://stdin
and then read from it with fgets()
for a line for example (or, as you already stated, fgetc()
for a single character):
<?php
$f = fopen( 'php://stdin', 'r' );
while( $line = fgets( $f ) ) {
echo $line;
}
fclose( $f );
?>
