The PASSWORD_BCRYPT duration evolves exponentially based on COST.
Measure picture : https://static.lortet.io/files/php.net.bcrypt_evolves.png
The "constant" depends on your machine (for me is 1).
Method :
<table border="1">
<?php
for( $cost = 0; $cost <= 10; $cost=$cost+0.1){
$start = microtime(true);
password_hash("test".$cost, PASSWORD_BCRYPT, ["cost" => $cost]);
$end = microtime(true);
echo '<tr><td>' . $cost . '</td><td>' . ( $end -
$start ) . '</td></tr>';
}
?>
</table>
