PHP gets the content between specified characters implementation code_PHP tutorial

php implementation code for obtaining the content between specified characters. This is a substring between two substrings in a string. For example, to obtain the hzhuti substring from the string www.hzhuti.com, let this PHP function Let’s implement it,

the code is as follows:

代码如下	复制代码
function get_between($input, $start, $end) {      $substr = substr($input, strlen($start)+strpos($input, $start),    (strlen($input) - strpos($input, $end))*(-1));      return $substr;    }    $string = "www.hzhuti.com";    $start = "www.";    $end = ".com";    echo get_between($string, $start, $end);  // output:hzhuti

However, this function has a limitation, that is, the $start substring and $end substring can only appear once in the entire string. Please see the example below:

代码如下	复制代码
$string = "http://www.hzhuti.com/";    $start = "http://";    $end = "/";

Obviously I want to get the domain name part of this standard URL. Since the $end substring is not unique in the entire string, problems will occur. Please be careful when using it!

Example

as
NAS/NMS COMPSITE (NasdaqSC:^IXIC) Quote data by ReutersIndex Value:2,030.08Trade Time:5:16PM ETChange: 35.40 (1.71%)Prev Close:2,065.48Open:2,072.95Day 's Range:2,026. 20 - 2,073.4252wk Range:1,359.32 - 2,153.831d

For such a string, I want to intercept the data 2,030.08 between Index Value: and Trade Time:. How to intercept it? I want a universal method

Code

The code is as follows

代码如下	复制代码
$str= "NAS/NMS COMPSITE (NasdaqSC:^IXIC) Quote data by ReutersIndex Value:2,030.08Trade Time:5:16PM ETChange: 35.40 (1.71%)Prev Close:2,065.48Open:2,072.95Day 's Range:2,026.20 - 2,073.4252wk Range:1,359.32 - 2,153.831d "; preg_match( " 'Index Value:(.+)Trade Time 's ",$str,$arr); if($arr){ echo $arr[ "1 "]; } ?>

Copy code

$str= "NAS/NMS COMPSITE (NasdaqSC:^IXIC) Quote data by ReutersIndex Value:2,030.08Trade Time:5:16PM ETChange: 35.40 (1.71%)Prev Close:2,065.48Open:2,072.95Day Range:2,0 26.20 - 2,073.4252wk Range:1,359.32 - 2,153.831d ";

preg_match( " 'Index Value:(.+)Trade Time 's ",$str,$arr);

if($arr){ echo $arr[ "1 "]; } ?> http://www.bkjia.com/PHPjc/631594.html
