1) leave first img tag
2) remove all another img tags
3) cut text by length
So you get simple text short text with one image on it.

This code tracks visits to your site 15 different bots. Naturally, the list can be extended – is represented by no means all of the existing ones.

Use it, you can read: let’s say your site has a template, and its “assembly” used files header.php ( “cap” of the site) and footer.php ( “basement”). Typically, these files are inserted at the beginning and end of each page on your site.
To carried out statistics on the Hits In of SE bots in this case, you must add the file header.php following code:

include("bot.php");

Now all the bots will be tracked and kept locked in a file bots.txt on your server.
PS. Do not forget to change CHMOD of bots.txt to 777

Thus, the code of Utf-8 has variable physical length of every character. In this connection sometimes there are problems at programming of multilanguage sites.

For example, in a programming of PHP of function of strlen and substr language give out improper results, if there are characters of national alphabet in a line (as intended for work with an onebyte code). Certainly, in PHP there are such functions as mb_strlen and mb_susbtr, specially intended for work with multibyte lines. But, by default support of Multibyte String Functions in PHP is turned off,that automatically limits the choice of khostinga for the designed site. In addition, during connecting of the module of mb_string the set of the supported languages is specified. And that is why there is probability, that the language required you can not appear in the list of supported.

However, there is other, more comfortable and flexible decision of problem. Taking advantage of functions of PCRE, correctly perceiving the code of Utf-8, it is possible to write the functions of utf8_strlen and utf8_substr:
