Using mktime() without arguments is not supported, and will result in an ArgumentCountError. time() can be used to get the current timestamp.
Syntax:
mktime(hour, minute, second, month, day, year)
Parameters:
mktime(hour (0-23), minute(0-59), second (0-59), month (1-12), day(1-31), year(four-digit))
Examples:
-Create a Unix timestamp for January
$timestamp = mktime(12, 0, 0, 1, 1, 2022);
echo $timestamp;
-Create a Unix timestamp for the current time
$hour = date('H');
$minute = date('i');
$second = date('s');
$month = date('n');
$day = date('j');
$year = date('Y');
$timestamp = mktime($hour, $minute, $second, $month, $day, $year);
echo $timestamp;
Points to consider:
1. `mktime()` assumes the input values are in the local timezone.
2. If no arguments are provided, `mktime()` returns the current Unix timestamp.
3. Be cautious when using `mktime()` with daylight saving time (DST) transitions.
PHP's explode() function:
Syntax:
explode(separator, string, limit)
Parameters:
1. separator - as a (string): The delimiter to split the string.
2. string - as a (string): The input string to be split.
3. limit -(int, optional): The maximum number of characters to be return.
Output :
Returns Array of strings
Examples:
Split a string by commas
$string = "apple,banana,cherry";
$fruits = explode(",", $string);
print_r($fruits);
Output:
Array ( [0] => apple [1] => banana [2] => cherry )
Notes to Remember:
1. explode() returns an array, even if only one element is found.
2. If limit is negative, explode() returns all elements except the last -limit -elements.
3. If separator is not found, explode()returns the original string as the only element.
