Extract a phrase from a string in php

Question

I have a string, extracted from the database, witch contains more phrases. I need to extract only first phrase witch is ending with a dot. somthing like this:
$string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";

and the result to be: Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Thanks in advance for idei(I am new in php).

$phrases = explode('.', $string, 2);
echo $phrases[0];

You forgot to add an dot at the end :p `echo $phrases[0] . ".";` – Joran Den Houting Sep 19 '13 at 13:49

You can use the 3rd param `limit` to prevent processing the rest of the string unnecessarily. – Scott Helme Sep 19 '13 at 13:49
@LazKarimov it would need to be a limit of 2 for it to work. – Scott Helme Sep 19 '13 at 13:57
Yes, that was it!, Laz Karimov. Thanks:) – Stefan C Sep 19 '13 at 14:35

As I mentioned above, you can use the 3rd param `limit` to prevent processing the rest of the string unnecessarily. – Scott Helme Sep 19 '13 at 13:50
Thanks Scott for a great addition :) I'll add it to my example. – Joran Den Houting Sep 19 '13 at 13:51

You need to explode it: http://php.net/manual/en/function.explode.php

$firstSentence = explode(".", $string, 2);
echo $firstSentence[0] . ".";

Edit to add . to end of echo.

Well, first find the position of the first dot. Then read the string up to and including the dot.

$lorem  = 'Lorem ipsum dolor sit amet...';
$dotpos = strpos($lorem, '.');
$phrase = substr($lorem, 0, $dotpos + 1);

Database level solution:

  SELECT SUBSTRING_INDEX('your.text.here', '.', 1)

Did they ask for SQL code? – Sverri M. Olsen Sep 19 '13 at 13:51
The question is tagged as `php`, and they use PHP code in the question. At no time was SQL mentioned. – Sverri M. Olsen Sep 19 '13 at 13:56

"I have a string, extracted from the database" I posted sql referring to this. – Kuzgun Sep 19 '13 at 13:57

Use substr() and strpos() in PHP

<?php
$string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";
echo (substr($string,0,strpos($string,'.')+1));
