Solution in PHP (judge verdict: Accepted)

<?php
// Your code here!
// fscanf(STDIN, "%d %d %d", $a,$r,$n);
$w = trim(fgets(STDIN));

$array = [];
while(true){
    $stdin = trim(fgets(STDIN));
    if($stdin == ""){
        break;
    }
    $array[] = explode(" ", $stdin);    
}
// var_dump($array);
$newarr = array_reduce($array, 'array_merge', array());
$ans = 0;
foreach($newarr as $v){
    if(strcasecmp($v, $w) == 0){
        $ans++;
    }
}
// var_dump($newarr);
echo $ans,PHP_EOL;

?>
