| 1 | timestamp (required) This specifies a timestamp. |
| 2 | format (optional) This specifies the format you need to use for the result value. You can pass three constants as the value of this parameter; i.e., SUNFUNCS_RET_STRING（string），SUNFUNCS_RET_DOUBLE（Floating point number) and SUNFUNCS_RET_TIMESTAMP Integer. |
| 3 | latitude (optional) By default, this option specifies the latitude of a location, which specifies the north direction. To specify the latitude value of the south, it needs to be passed as a negative value. |
| 4 | longitude (optional) By default, it specifies the longitude of a location, which specifies the east direction. To specify the longitude value of the west, it needs to be passed as a negative value. |

The following example demonstratesdate_sunrise()Function usage-
<?php
$sun_info = date_sunrise("02-17-2012");
print_r($sun_info);
?>Test and see‹/›Output result

?>Test and see‹/›Output result

The following example verifies the case with no sunrise-
<?php
$sun_info = date_sunrise("25-12-2016", SUNFUNCS_RET_STRING, 69, 41
print("Sunrise Time: ").$sun_info,
print("\n");
var_dump($sun_info);
?>Test and see‹/›Output result
Sunrise Time: bool(false)
<?php
echo("Date: ".date("D M d Y"));
echo("\n");
echo("Sunrise time: ");
echo(date_sunrise(time(), SUNFUNCS_RET_STRING,38.4,-9,90,1));
?>Test and see‹/›Output result
