如何在PHP中使用逗号从数组中创建单个qoutes列表？

这是我的问题，我有这种类型的字符串

04/19/2017, 04/20/2017, 04/26/2017, 04/28/2017

我想输出如下输出

'04/19/2017','04/20/2017','04/26/2017','04/28/2017'

对于您的特定示例，您可以使用：

$result = preg_replace('%([\d/]+)%sim', '"\1"', $string);

---

输出：

"04/19/2017", "04/20/2017", "04/26/2017", "04/28/2017"

正则表达式解释：

([\d/]+)

Match the regex below and capture its match into backreference number 1 «([\d/]+)»
   Match a single character present in the list below «[\d/]+»
      Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
      A “digit” (any decimal number in any Unicode script) «\d»
      The literal character “/” «/»

"\1"

Insert the character “"” literally «"»
Insert the text that was last matched by capturing group number 1 «\1»
Insert the character “"” literally «"»

不使用爆炸和内爆

$string=“2017年4月19日、2017年4月20日、2017年4月26日、2017年4月28日”；
$string=“””。str_替换（“，”，“，”，“，$string）。”
查看和。您应该粘贴您的代码，然后添加正则表达式的解释？

<?php
// dates in a string
$data = '04/19/2017, 04/20/2017, 04/26/2017, 04/28/2017';

// break them apart into array elements where the , is
$dates = explode(',', $data);


/* You then have array of dates you can use/display how you want, ie:: */
foreach($dates as $date){
    echo $date. '<br/ >';
}

/* OR select single date */
echo $dates[0];
