如何通过点爆炸字符串时排除图像

Question

I have this string for example:

 $str = 'The quick fox. <img src="image.jpg" /> Jumped over. The lazy Dog.';

I need to get the first two sentence (or first two dots). How can I skip <img src="image.jpg" /> from being exploded when using $arr = explode('.', $str);

Here's my current code.

$len   = 2;
$arr    = explode('.',  $str);
$arr2   = array_slice($arr, 0, $len);

$str = implode('.', $arr2).'.';

Answer 1

you can use strip_tags function to remove all html tags from the string.

like this

$arr = explode('.', strip_tags($str));

for more information http://php.net/manual/en/function.strip-tags.php

--Edit--

$arr = explode('.', strip_tags($str)); 

will not modify ur original string.it remains as it is.

$str = 'The quick fox. <img src="image.jpg" /> Jumped over. The lazy Dog.';
$arr = explode('.', strip_tags($str));
print_r($arr);
//output :- Array ( [0] => The quick fox [1] => Jumped over [2] => The lazy Dog [3] => ) 
echo "<br/>".$str;
//output :- The quick fox. <img src="image.jpg" /> Jumped over. The lazy Dog.
