php7 performance test

The execution code is as follows:

$start_time = microtime(true);

$a = array();

for($i=0;$i<90000;$i++){

$a[$i] = $i;

}

foreach($a as $i)

{

array_key_exists($i, $a);

in_array($i, $a);

}

$end_time = microtime(true);

echo "use time=".($end_time - $start_time);

in Time spent on php5.5.30:

use time=68.47440290451

It takes time to execute after installing php7 in the virtual machine

use time=8.4918169975281

The above has introduced the php7 performance test, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
