Detailed explanation of the method of checking whether it matches the specified time period in PHP

Due to the needs of work development, it is necessary to determine whether a time is within a specified time period, and it needs to support the determination of days of the week and spans of days, so I wrote the following method and shared it with everyone to learn and use.

The code is as follows:

<?php/**
 * 判断时间是否匹配指定时间段
 *
 * Date:    2017-10-29
 * Author:  fdipzone
 * Version: 1.0
 *
 * @param  Array    $config  指定日期时段设定
 * @param  Int      $time    判断的日期时间，默认为当前日期时间
 * @return Boolean
 */function check_time_match($config, $time=null){

    $curtime = isset($time)? $time : time();    // 当前周几
    $curw = date(&#39;w&#39;, $curtime);    // 上一天周几
    $prew = date(&#39;w&#39;, $curtime-86400);    // 当前时分
    $curhm = date(&#39;H:i&#39;, $curtime);    // 循环指定日期时段，检查是否匹配
    foreach($config as $k=>$v){        // 循环时段
        foreach($v[&#39;range&#39;] as $t){            list($range, $next_day) = explode(&#39;,&#39;, $t);            // 获取时段的开始结束时间
            list($starttime, $endtime) = explode(&#39;-&#39;, $range);            // 当天
            if($next_day==0){                // 检查周几是否匹配
                if(in_array($curw, $v[&#39;week&#39;])){                    // 检查时间是否匹配
                    if($curhm>=$starttime && $curhm<=$endtime){                        return true;
                    }

                }            // 跨天
            }else{                // 检查当天周几是否匹配
                if(in_array($curw, $v[&#39;week&#39;])){                    // 检查当天时间是否匹配，开始时间－当天零点
                    if($curhm>=$starttime){                        return true;
                    }

                }                // 检查上一天周几是否匹配
                if(in_array($prew, $v[&#39;week&#39;])){                    // 检查上一天时间是否匹配，当天零点－结束时间
                    if($curhm<=$endtime){                        return true;
                    }

                }

            }

        }

    }    return false;

}?>

demo:

<?php// 指定日期时段设定$config = array(    array(        &#39;week&#39; => array(1,2,3,4,5), // 周一至周五
        &#39;range&#39; => array(&#39;08:00-12:00,0&#39;, &#39;14:00-18:00,0&#39;, &#39;20:00-22:00,0&#39;)
    ),    array(        &#39;week&#39; => array(0,6), // 周六周日
        &#39;range&#39; => array(&#39;08:00-18:00,0&#39;, &#39;20:00-02:00,1&#39;), // 0:不跨天，1:跨天
    )
);// 检查时间是否匹配$check_time = array(    null,               // 当前日期时间,2017-10-29 11:40 周日
    &#39;2017-10-23 11:00&#39;, // 周一
    &#39;2017-10-24 12:01&#39;, // 周二
    &#39;2017-10-25 19:59&#39;, // 周三
    &#39;2017-10-26 21:59&#39;, // 周四
    &#39;2017-10-27 22:00&#39;, // 周五
    &#39;2017-10-28 12:01&#39;, // 周六
    &#39;2017-10-28 18:01&#39;, // 周六
    &#39;2017-10-29 01:59&#39;, // 周日
    &#39;2017-10-30 01:59&#39;, // 周一
    &#39;2017-10-30 02:01&#39;, // 周一
    &#39;2017-10-31 01:59&#39;, // 周二);foreach($check_time as $time){
    var_dump(check_time_match($config, strtotime($time)));
}?>

Output:

boolean trueboolean trueboolean falseboolean falseboolean trueboolean trueboolean trueboolean falseboolean trueboolean trueboolean falseboolean false
