PHP randomly extracts titles from the content

<? Php

 

$ Temp = $ LabelArray ['content'];

$ Temp = preg_replace ("% <[^>] +> %", ',', $ temp); // prevent matching of letters on the website

$ Temp = make_semiangle ($ temp); // halfwidth Conversion

If (preg_match_all ("% [[: punct:] ([^ [: punct:] {5, 30}) [[: punct:] % u", $ temp, $ arr )){

$ I = rand (0, count ($ arr [0])-1 );

$ LabelArray ['title'] = $ arr [1] [$ I];

}
