![]() So just use whatever function makes the most practical and readable sense to you as a programmer. ![]() There are perturbations including other processes running that are interfering with the execution times. According to these quick and dirty tests, any of the six chosen functions will get the job done in a reasonable amount of time. Strpos/ substr: 1.0082197189331E-7 secondsĬonclusion It turns out that the speed between these functions varies widely and is not as consistent between test runs as you might expect. Str_word_count: 3.7025549411774E-6 secondsĪnd the results after inverting the order of the functions: strtok: 4.2612719535828E-7 seconds ![]() This is a good practice generally when using the global scope for your helper functions.If you want to know how fast each of these respective functions is, I ran some crude benchmarking in PHP 7.3 on the six most voted answers here ( strpos with substr, explode with current, strstr, explode with trim, str_word_count and strtok) with 1,000,000 iterations each to compare their speeds. This keeps it from breaking in case you upgrade and forget that you added it. If you do not have PHP 8, you can use these functions to get the capability of the new string functions.īut! Remember to use a conditional check to make sure the function is not already defined. With credit to Paul Phillips for the original polyfill posted.
