PHP localtime() Function

The PHP localtime() function returns the local time. The array by this function is identical to that of the structure returned by the C function call.

Syntax

localtime(timestamp, associative)

Parameters

Return Value

If associative is set to true the function returns an associative array otherwise returns a numerically indexed array. The keys of the associative array are as follows:

• [tm_sec] - seconds, 0 to 59
• [tm_min] - minutes, 0 to 59
• [tm_hour] - hours, 0 to 23
• [tm_mday] - day of the month, 1 to 31
• [tm_mon] - month of the year, 0 (Jan) to 11 (Dec)
• [tm_year] - years since 1900
• [tm_wday] - day of the week, 0 (Sun) to 6 (Sat)
• [tm_yday] - day of the year, 0 to 365
• [tm_isdst] - is daylight savings time in effect? Positive if yes, 0 if not, negative if unknown.

Exceptions

If the time zone is not valid, generates a E_WARNING.

Example: localtime() example

The example below shows the usage of localtime() function.

<?php
//displaying the local time as
//a numerically indexed array
echo ("The local time is :\n");
print_r(localtime());
?>

The output of the above code will be:

The local time is :
Array
(
    [0] => 31
    [1] => 6
    [2] => 7
    [3] => 30
    [4] => 8
    [5] => 121
    [6] => 4
    [7] => 272
    [8] => 0
)

Example: using associative parameter

When associative parameter is set to true, the function returns an associative array as shown in the example below:

<?php
//displaying the local time as
//an associative array
echo ("The local time is :\n");
print_r(localtime(time(), true));
?>

The output of the above code will be:

The local time is :
Array
(
    [tm_sec] => 28
    [tm_min] => 9
    [tm_hour] => 7
    [tm_mday] => 30
    [tm_mon] => 8
    [tm_year] => 121
    [tm_wday] => 4
    [tm_yday] => 272
    [tm_isdst] => 0
)
