Reading input in php from terminal

I want to read the following input in php which is entered in termial

3
5  
1 4 0 2 5  
2 0 5 1 4  
4  
1 1 7 2
1 13 2 1 
3
3 1 7
2 5 4 

Where:

• The first line of input consists of an integer T which is the number of test cases.
• The first line of each test case contains an integer n which indicates the size of both arrays.
• The second and third line of each test case contains n space separated integers which are the elements of the first and second arrays respectively.

I am new to PHP, can anybody explain me the code logic of reading the input?

I don’t want to store the input in a file and read it from there.

Any help would be appreciable, Thank you.

Answer

function read_from_console ($prompt = '') {
    if ( function_exists('readline') ) { 
        $line = trim(readline($prompt));
        if (!empty($line)) {
            readline_add_history($line);
        }
    } else {
        echo $prompt;
        $line = trim(fgets(STDIN));
    }
    return $line;
}

$values = preg_split('/s+/', trim(read_from_console()));
