$str = "CSS, HTML, PHP, Java, JavaScript" For example, if you specify 2, all the strings would show, but the index won’t be more than 2. If you specify a limit in the explode() function, the index(es) won’t be more than that number. ![]() We are printing an array, so we can use print_r() Remember that arrays use zero-based indexing. If the string is passed into an explode() function, Hello takes an index of 0 in the array, and World takes an index of 1. ![]() Let's say that I have the string "Hello World". You can use the limit parameter to specify the number of arrays expected. So, just like the string split into an array, the separator is required. Unlike implode() which works even if the separator is not provided, the explode() function won’t work without the separator. The full syntax looks like this: explode(separator, string, limit) The explode() function takes in three parameters: Like the built-in implode() function, the explode function does not modify the data (string). Each of the characters in the string is given an index that starts from 0. I do not have much programming in php and I hope I can help those that I want to do is that when entering in the form the date 1 and the date2 I calculate if between those two dates if they have passed 5 or more years and I add 3 more days taking As reference date 2, I do not know if I understand.The PHP explode() function converts a string to an array. My simple function to count up the number of weekdays between the dates (inclusive for both ends), one can add a holidays between the dates to take them into account as well as the weekends, the weekend days could also be changed.įunction count_week_days($_date_from, $_date_to, $_holidays_between=array(), $_weekend_days=array(5,6)). Do this for each date, then return the absolute value of the difference. So in the functions below, we find the total numbers of days in full years since the mythical, then add the number of days before the current one in the year passed. ![]() unless the year is divisible by 400, then it really is. unless the year is divisible by 100, then it isn't. If the year is divisible by 4, it's a leap year. It looks a little insane, but keep in mind the full set of rules for leap years: You can change to a different unit from that. ![]() If you want to find out the number of days between two dates, use below. It should work between 19, but outside that it'll be a little off. $total = ((( $diff -> y * 365.25 + $diff -> m * 30 + $diff -> d ) * 24 + $diff -> h ) * 60 + $diff -> i )* 60 + $diff -> s Įven the top rated comment here, Sergio Abreu's, doesn't treat leap years entirely correctly.
