This article illustrates the method of PHP to calculate title title similarity ratio. Share to everyone for your reference. Specifically as follows:

<?php 
/
 * *
 @param string $title _1 topic 1
 * @param string $title _2 Title 2
 * @return Similar percentage of float $percent
 * *
function title_similar ($title _1, $title _2) {
  $title _1 = get_real_title ($title _1);
  $title _2 = get_real_title ($title _2);
  Similar_text ($title _1, $title _2, $percent);
  return $percent;
}
/**
 * PHP collect article title and copyright
 * @param string $html The HTML source code to be collected
 * @return string
 /
function Get_real_ Title ($STR) {
  $str = str_replace (Array ('-', '-', ' | '), ' _ ', $str);
  $splits = Explode (' _ ', $str);
  $l = 0;
  foreach ($splits as $TP) {
    $len = strlen ($TP);
    if ($l < $len) {$l = $len; $tt = $TP;}
  }
  $tt = Trim (Htmlspecialchars ($TT));
  return $tt;
}
The following is the test
$title _1 = ' Code PHPCMS V9 products officially released public beta version ';
$title _2 = ' Phpcms V9 products officially released public beta version ';
$percent = Title_similar ($title _1, $title _2);
echo ' similar percentage: '. $percent. ' %';
echo "<br/>\n";
