Question

你好我有一个数组如下。

$testArray = array
    (
        '12 AM - 01 AM',
        '01 AM - 02 AM',
        '02 AM - 03 AM',
        '03 AM - 04 AM',
        '04 AM - 05 AM',
        '06 AM - 07 AM',
        '07 AM - 08 AM',
        '08 AM - 09 AM',
        '09 AM - 10 AM',
        '10 AM - 11 AM',
        '11 AM - 12 PM',
        '12 PM - 01 PM',
        '01 PM - 03 PM',
        '03 PM - 04 PM'
    );

现在我只想将字符串显示为

 12 AM -05 AM,06 AM - 04 PM

请小小的提示或帮助可以节省我的时间。感谢名单...

Answer 1

这是一些输出的工作示例代码：

12 AM - 05 AM, 06 AM - 04 PM

您可以使用此功能，也可以根据需要对其进行编辑：

<?php

    $testArray = array
    (
        '12 AM - 01 AM',
        '01 AM - 02 AM',
        '02 AM - 03 AM',
        '03 AM - 04 AM',
        '04 AM - 05 AM',
        '06 AM - 07 AM',
        '07 AM - 08 AM',
        '08 AM - 09 AM',
        '09 AM - 10 AM',
        '10 AM - 11 AM',
        '11 AM - 12 PM',
        '12 PM - 01 PM',
        '01 PM - 03 PM',
        '03 PM - 04 PM'
    );

$now = time();
foreach($testArray as $trange){
    $matches = array();
    preg_match_all('/(\d+ (?:A|P)M) - (\d+ (?:A|P)M)/', $trange, $matches);
    if(!isset($start)){
        $start = $matches[1][0];
        $end = $matches[2][0];
    }else if(strtotime($end, $now) === strtotime($matches[1][0], $now))
        $end = $matches[2][0];
    else{ // End time not equal to previous start time
        echo $start , ' - ' , $end, ', '; 
        $start = $matches[1][0];
        $end = $matches[2][0];
    }
}

echo $start , ' - ' , $end;

?>

Using string functions:

$temp = explode('-',$testArray[0]);
        $start_str = $temp[0];
        $comma = '';

for ($i = 0; $i <= count($testArray); $i++) {

        $temp = explode('-',$testArray[$i]);

        $prev_start = $temp[0];
        $prev_end = $temp[1];
        $prev_endtime = (integer) $prev_end;

        $temp = explode('-',$testArray[$i+1]);
        $start = $temp[0];
        $end = $temp[1];

        $starttime = (integer) $start;
        if($prev_endtime != $starttime){
            $op .= " $comma $start_str - $prev_end";
             $comma = ',';
            $start_str = $start;
        }
}
echo $op;

PHP Date Array到用户友好的字符串
