![]() ![]() Remember to measure the execution time of the specific code you want to analyze rather than the entire script if you're interested in a specific portion's performance.'. You can choose the method that suits your requirements best. These are some of the common ways to measure script execution time in PHP. This allows you to analyze the performance and memory consumption of your script. The output will display the script execution time in seconds and the peak memory usage in bytes. You can place this code snippet at the beginning and end of the section you want to measure. In this example, the microtime(true) function is used to get the current timestamp with microseconds, and the memory_get_peak_usage() function is used to get the peak memory usage in bytes. $memoryUsage = $endMemory - $startMemory Įcho "Peak memory usage: ". Code to measure execution time and memory usage Here's an example of measuring script execution time and peak memory usage using the microtime(true) function in combination with the memory_get_peak_usage() function in PHP: Note that the hrtime() function provides more accurate timing measurements compared to microtime() or time() functions. The output will display the script execution time in seconds with high precision. By subtracting the start time from the end time and dividing it by 1e9 (10^9), we obtain the total execution time in seconds. ![]() In this example, the hrtime(true) function is used to get the current high-resolution time in nanoseconds. $executionTime = ($end - $start) / 1e9 // Convert to seconds Here's an example of measuring script execution time using the hrtime() function in PHP (available in PHP 7.3 and later): If you require more precise measurements, you may want to consider using the microtime() function instead. However, please note that the time() function only provides accuracy up to a second. The output will display the script execution time in seconds. By subtracting the start time from the end time, we obtain the total execution time in seconds. In this example, the time() function is used to get the current timestamp as a Unix timestamp (the number of seconds since January 1, 1970). Here's an example of measuring script execution time using the time() function in PHP: In this example, the microtime(true) function is used to get the current timestamp with microseconds. Here's an example of measuring script execution time using the microtime() function in PHP:Įcho "Script execution time: ". Using the microtime(true) function in combination with the memory_get_peak_usage() function to measure peak memory usage Using the hrtime() function (available in PHP 7.3 and later) There are several ways to measure script execution time in PHP. ![]() PHP scripts are executed on the server, and the resulting HTML is sent to the client's browser. It allows developers to embed PHP code within HTML, making it easy to mix server-side logic with the presentation layer. PHP is primarily used to develop dynamic web pages and web applications. It was originally created by Rasmus Lerdorf in 1994 and has since evolved into a powerful language used by millions of developers worldwide. PHP: PHP (Hypertext Preprocessor) is a widely-used open-source server-side scripting language that is specifically designed for web development. ![]()
