How can I delete all the text after the point, while leaving the text to the point? It should be borne in mind that there may not be a point in the text, then you do not need to trim anything. Symbols can be both Cyrillic and Latin, using utf8.

  • php.net/manual/ru/function.mb-strstr.php - Mike
  • Need to leave a point? Or anyway? - cheops
  • @cheops yes, you need it, but as far as I understand it, if you use the function proposed by Mike, you will get something like this: $ var = strstr ($ var, '.', true); $ var = $ var. '.'; - misc

$str="тестовая строка"; $a=mb_strstr($str,".",true); if($a) $str=$a."."; print $str;

Option a bit faster than using regular expressions.

    You can do the following if you want to save the point

     <?php $text = 'до точки.после точки'; echo preg_replace('/(?<=\.).*$/u', '', $text);

    and so if it is not needed

     <?php $text = 'до точки.после точки'; echo preg_replace('/\..+$/u', '', $text);

      (?<=\.).*$ requires 13 steps of the regularizer for the string "123.456". plus 2 steps for each character. Similar \.\K.*$ - only 5 steps, since just runs along the line, searches for a point, steps over it and takes everything to the end of the line, backtracking is excluded - Mike
    • Accepted, thank you. - cheops

    I will offer another option:

     $str = 'Lorem ipsum dolor sit amet. Consectetur adipiscing elit.'; $str = explode( '.', $str )[0]; echo $str;
