從一個字符串中提取日期php

Question

我需要從一個字符串中提取日期：例如字符串是「...從06/01/2014到2014年6月30日的期間」。我怎樣才能提取這兩個日期爲：

$date1 = "06/01/2014"; 
$date2="06/30/2014"; 

Answer 1

這樣

$string = "period from 06/01/2014 to 06/30/2014"; 

$results = array(); 

preg_match_all('#\d{2}/\d{2}/\d{4}#', $string, $results); 

$date1 = $results[0][0]; 
$date2 = $results[0][1]; 

Answer 2

正則表達式是你最好的選擇。

<?php 
$string = "period from 06/01/2014 to 06/30/2014"; 

$pattern = "/(\d{2}\/\d{2}\/\d{4})/"; 

preg_match_all($pattern, $string, $matches); 

$date1 = $matches[0][0]; 
$date2 = $matches[0][1]; 

echo "Date1: " . $date1 . "<br />"; 
echo "Date2: " . $date2; 

輸出：

Date1: 06/01/2014 
Date2: 06/30/2014
