How to read console/user input in PHP?

I use gets to get an user input in Ruby.

# in 0015.rb
input_num = gets.to_i
p "Your input number is #{input_num}."

And I use it in a terminal.

➜  rubytest: ruby 0015.rb
24
"Your input number is 24."

Can I do like this in PHP with terminal?

You can use readline function. But if you search for array input then you have to also use explode function. See given example for get array input,

<?php 
    //input 1 6 5
    $a = explode(' ', readline()); //read array
    for($i=0;$i<sizeof($a);$i++)
    {
       echo $a[$i]." ";
    }

?> 
Output:
1 6 5

Using fscanf() function works same as the fscanf() function in C. We can read 2 integers from Keyboard(STDIN) as below:

This is defferent from the previous method

<?php 
  
// Input 1 5 
fscanf(STDIN, "%d %d", $a, $b); 
   
// Output 
// The sum of 1 and 5 is 6 
echo "The sum of " . $a . " and "
    . $b . " is " . ($a + $b); 
?> 


Output:
The sum of 1 and 5 is 6

If you don't have readline installed, -or- you're writing a library, you should do this:

if (!function_exists('readline')) {
    function readline($question)
    {
        $fh = fopen('php://stdin', 'r');
        echo $question;
        $userInput = trim(fgets($fh));
        fclose($fh);

        return $userInput;
    }
}

$age = readline('What is your age? ');
echo "You are $age years old.\n";

I think you are looking for the readline function

$number = readline("Enter a number: ");
echo 'You picked the number: '.$number;
