PHP Time Comparison

/**
* PHP Time Comparison
*/
Define the start time, notice that the time is a string format, so you must enclose the error in quotation marks Otherwise, do not call me, and the colon inside must be a colon
$start _time = ' 7:00 ';

Define the end time, don't ask me why I wrote 18 in the six o'clock in the afternoon, I would suggest you re-read primary school.
$end _time = ' 18:00 ';

Get the current time period, the use of the date () function I will not talk nonsense, do not understand directly read the previous article or Google
$now _time = Date (' h:i ');

Judge
if ($start _time<= $now _time && $end _time>= $now _time) {
Echo ' I want to post a message! ‘;
}else{
Echo ' elder brother, now only what time AH ~ ~ ~ People have not been awake yet!!! ‘;
}
