hashtag后面的字符串中的特定于样式的单词-php

我的场景：我尝试在字符串中的hashtag后面设置一些名称的样式

例如：

$string = 'Lorem #Stewie Smith ipsum dolor #Peter Griffin sit amet, consectetuer #Stewie Griffin.';

首先，我想将这些名称放入如下数组：

array(

    [item 1]
    [firstname] => 'Peter'
    [surname] => 'Griffin'

    [item 2]
    [firstname] => 'Stewie'
    [surname] => 'Griffin'

    [item 3]
    [firstname] => 'Stewie'
    [surname] => 'Smith'

)

因此，我可以在数组中循环并检查数据库中是否存在名字和姓氏

数据库数据：

|id |名|姓|

|1 |彼得|格里芬|

|2 |斯图迪|史密斯|

验证之后，我喜欢在字符串中的名字和姓氏周围加一个div

谁知道答案

提前感谢

您需要使用正则表达式：

//Regular expression (explained below)
$re = "/\\#([a-zA-Z]*)\\s([a-zA-Z]*)/"; 

//String to search
$str = "Lorem #Stewie Smith ipsum dolor #Peter Griffin sit amet, consectetuer #Stewie Griffin."; 

//Get all matches into $matches variable
preg_match_all($re, $str, $matches);

$matches

现在是：

Array ( [0] => Array ( [0] => #Stewie Smith [1] => #Peter Griffin [2] => #Stewie Griffin ) [1] => Array ( [0] => Stewie [1] => Peter [2] => Stewie ) [2] => Array ( [0] => Smith [1] => Griffin [2] => Griffin ) ) 将其放入数组：

$names = [];

foreach($matches[0] as $i => $v){
    $names[] = array("firstname" => $matches[1][$i], "lastname" => $matches[2][$i]);
}

现在，

$names

是：

Array ( [0] => Array ( [firstname] => Stewie [lastname] => Smith ) [1] => Array ( [firstname] => Peter [lastname] => Griffin ) [2] => Array ( [firstname] => Stewie [lastname] => Griffin ) ) 排列 ( [0]=>阵列 ( [名字]=>Stewie [姓氏]=>史密斯 ) [1] =>阵列 ( [名字]=>彼得 [姓氏]=>格里芬 ) [2] =>阵列 ( [名字]=>Stewie [姓氏]=>格里芬 ) )

从这里，您可以循环使用此数组，检查数据库，根据需要进行验证，然后对结果数据执行任何操作。

谁知道答案？我愿意！我赢了什么？A非常感谢：你先生赢了“非常感谢”！谢谢！整天编码有时会让你的脑袋有点晕；） Array ( [0] => Array ( [firstname] => Stewie [lastname] => Smith ) [1] => Array ( [firstname] => Peter [lastname] => Griffin ) [2] => Array ( [firstname] => Stewie [lastname] => Griffin ) )
