Find the test file bench.php. There are a lot of test codes written in this file, such as
// 执行一百万次字符串 hallo 长度的计算
function simplecall() {
for ($i = 0; $i < 1000000; $i++)
strlen("hallo");
}Execute /usr/local/php-5.6.8/bin/php bench.php, the test results are as follows

Through comparison, it is found that the performance of PHP 7 has improved significantly. PHP 5 takes about 25 seconds to execute the test code, while PHP 7 does not exceed 4 seconds. In addition, PHP 7.4 has much better performance than PHP 7.2 improvement. Of course, the test results will be different in different test environments, but the performance improvement is definitely the same.
In addition, the Zend directory also has a more complex test file micro_bench.php. Interested partners can test it by themselves. If the stable version of PHP 8 is officially released, friends can also experience the performance of PHP 8 for themselves.
The above is the detailed content of About the performance comparison between PHP5 and PHP7. For more information, please follow other related articles on the PHP Chinese website!
