readline_callback_handler_install
READLINE_CALLBACK_HANDLER_INSTALL(3) 1 READLINE_CALLBACK_HANDLER_INSTALL(3)readline_callback_handler_install - Initializes the readline callback interface and terminal, prints the prompt and returns immediatelySYNOPSIS
bool readline_callback_handler_install (string $prompt, callable $callback)
DESCRIPTION
Sets up a readline callback interface then prints $prompt and immediately returns. Calling this function twice without removing the previ-
ous callback interface will automatically and conveniently overwrite the old interface.
The callback feature is useful when combined with stream_select(3) as it allows interleaving of IO and user input, unlike readline(3).
PARAMETERS
o $prompt
- The prompt message.
o $callback
- The $callback function takes one parameter; the user input returned.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
Example #1
Readline Callback Interface Example
<?php
function rl_callback($ret)
{
global $c, $prompting;
echo "You entered: $ret
";
$c++;
if ($c > 10) {
$prompting = false;
readline_callback_handler_remove();
} else {
readline_callback_handler_install("[$c] Enter something: ", 'rl_callback');
}
}
$c = 1;
$prompting = true;
readline_callback_handler_install("[$c] Enter something: ", 'rl_callback');
while ($prompting) {
$w = NULL;
$e = NULL;
$n = stream_select($r = array(STDIN), $w, $e, null);
if ($n && in_array(STDIN, $r)) {
// read a character, will call the callback when a newline is entered
readline_callback_read_char();
}
}
echo "Prompting disabled. All done.
";
?>
