CLI-Prompt

While prompting for user input using fgets() is quite easy, sometimes you need to prompt for sensitive information. In these cases, the characters typed in by the user should not be directly visible, and this is quite a pain to do in a cross-platform way.

This tiny package fixes just that for you:

<?php

echo 'Say hello: ';

$answer = Seld\CliPrompt\CliPrompt::hiddenPrompt();

echo 'You answered: '.$answer . PHP_EOL;

// Output in the CLI:
// 
// Say hello:
// You answered: hello

Installation

composer require seld/cli-prompt

API

  • Seld\CliPrompt\CliPrompt::hiddenPrompt($allowFallback = false);

    Prompts the user for input and hides what they type. If this fails for any reason and $allowFallback is set to true the prompt will be done using the usual fgets() and characters will be visible.

  • Seld\CliPrompt\CliPrompt::prompt();

    Regular user prompt for input with characters being shown on screen.

In both cases, the trailing newline the user enters when submitting the answer is trimmed.

Requirements

PHP 5.3 and above
