如何應用此正則表達式？在php

Question

如何應用這個正則表達式？在Php 我有代碼

$a = "{temp}name_temp1{/temp} Any thing Any thing {temp}name_temp2{/temp}"; 

我只需要name_temp1和name_temp2

任何名稱裏面{溫度} 這 {/ TEMP}

感謝您

Answer 1

你可以使用一個懶惰的量詞：

{temp}   # look for {temp} 
(?P<value>.+?) # anything else afterwards 
{/temp}  # look for {/temp} 

---

在 PHP這將是：

<?php 

$a = "{temp}name_temp1{/temp} Any thing Any thing {temp}name_temp2{/temp}"; 

$regex = '~{temp}(?P<value>.+?){/temp}~'; 
preg_match_all($regex, $a, $matches, PREG_SET_ORDER); 

foreach($matches as $match) { 
    echo $match["value"]; 
} 
?> 

Answer 2

試試這個正則表達式：{temp}(.*?){\/temp}

而且你可以使用它在PHP這樣的：

$a = "{temp}name_temp1{/temp} Any thing Any thing {temp}name_temp2{/temp}"; 

preg_match_all('/{temp}(.*?){\/temp}/', $a, $matches); 

var_dump($matches[1]); // Returns ['name_temp1', 'name_temp2']
