Question

我在数据库中有这样的字符串。很抱歉，但我可以更改数据库。

TuesLunch|MonLunch|MonDinner|TuesBKfast

所以一般来说它的所有日子都有晚餐，午餐和BKfast 现在我想让这个字符串在php中显示如下

Tues Lunch 
Mon Lunch 
Mon Dinner
Tues BKfast

到目前为止我已经完成了

$weekdays = TuesLunch|MonLunch|MonDinner|TuesBKfast;
$days = explode('|',$weekdays);

有人能告诉我怎么做吗？任何帮助和建议都会非常明显。感谢

Answer 1

您可以使用基本为preg_split的{{1}}和正则表达式:(正则表达式拼写为大写字母）

explode()

Answer 2

您可以使用正则表达式执行此操作：

$weekdays = "TuesLunch|MonLunch|MonDinner|TuesBKfast";
$days = explode('|', $weekdays);

$strings = [];
foreach ($days as $day) {
  preg_match_all('/[A-Z][^A-Z]*/', $day, $results);
  $strings[] = implode($results[0], ' ');
}
print_r($strings);

Answer 3

这将按预期工作：

$weekdays = "TuesLunch|MonLunch|MonDinner|TuesBKfast";
$days = explode('|', $weekdays);

function spacify($str, $delim = ' ') {
    $str = preg_replace('/([a-z0-9])([A-Z])/', "$1$delim$2", $str);
    return $str;
}

foreach (spacify($days) as $key => $val){
    echo $val."<br>";
}

php爆炸值并创建空格
