How to measure the script execution time?

I just use super simple calculation that uses microtime function for getting the timestamp at the beginning and on the end of the operation.

$start = microtime(true);

get_posts([
  'post_type' => 'post',
  'posts_per_page' => 1000,
]);

printf(microtime(true) - $start);

Put the code between the functions and you'll get the results. Simple, but really useful! You can save this simple code snippet in your vscode settings and use measure keyword for adding this immediately to your code.

"measure": {
  "prefix": "measure",
  "body": [
    "\\$start = microtime(true);",
    "printf(microtime(true) - \\$start);"
  ]
},
