Remove text after last full stop " . "

i want to remove all the text after the last occurring of " . " in a given paragraph.

For example from this paragraph i want to remove all text after last full stop.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making开发者_Go百科 it over 2000 years old. Rich

Length of the paragraph is dynamic only thing to be removed is text after last " . "

You can do this with strrpos and substr:

$pos = strrpos($paragraph, '.');
$withOutDot = substr($paragraph, 0, $pos). '.';

Maybe something like this:

new_string = substr(old_string, 0, strchr(old_string, '.'));

strchr finds the position of the last occurrence of '.' in old_string. substr returns a new string consisting of the characters in old_string between positions 0 and the position found by strchr.

For me, the above solutions didn't work out so finally i got some code by myself so it may help to other people.

<?php 
    $trim_content = "Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Rich";
    $place = strripos($trim_content,".");
    $content = substr($trim_content,$place);
    echo str_replace($content,".",$trim_content);
?>

You can do it with explode.

$summary = explode(".",$summary);

$summary=$summary[1]

here you will get text till the first full stop
