<?php
$n_matrix_val=4;
for ($y = 1; $y <= $n_matricx_val; $y++) {
   fscanf(STDIN ,"%s\n", $the_matricx_val);
   fwrite(STDOUT, $the_matricx_val);
}

My input is: 

5 8 9 7
3 4 9 8
1 5 4 9
3 2 7 6

and my out put is:

5313

You can also do :

<?php 
    $i=trim(fgets(STDIN));
?>

This code will get you the whole line.

Your pattern is worng. Try this.

$n_matrix_val = 4;
for ($y = 1; $y <= $n_matrix_val; $y++)
    {
    $the_matricx_val = fscanf(STDIN, "%s %s %s %s");
    fwrite(STDOUT, implode(' ', $the_matricx_val) . PHP_EOL);
    }

But if you want to read whole line just use fgets.

    $the_matricx_val = fgets(STDIN);
    fwrite(STDOUT, $the_matricx_val);

Use "%[^\n]s" to get whole line:

$n_matricx_val=4;

for($y=1;$y<=$n_matricx_val;$y++)
{
    fscanf(STDIN ,"%[^\n]s", $the_matricx_val);
    fwrite(STDOUT, $the_matricx_val . "\n");
}
