search mysql column with similar_text() matching percentage

i want to echo one value from mysql column which is 90% similar to php variable. echo only the value that is 90% similar to php value. i think like clause wont help in this case.

<?php
  $x = $_GET[x];
  $con=mysqli_connect("example.com","peter","abc123","my_db");
  $res =  mysqli_query($con,"SELECT * FROM text");
  while ($row = mysql_fetch_assoc($res))
 {
     $string[] = $row['text'];
 }
  foreach ($string as $y)
 {
  similar_text($x, $y, $percent);
 }
  if ($percent>"90")
 {
   echo $string ; 
  ?>

i think the above code has many mistakes. i welcome some new solution for my task.

finally myself i found the solution for this and its working too.
<?php
$con=mysqli_connect("localhost","user","pass","table");
$dbf = mysqli_real_escape_string($con, $f);
if(mysqli_num_rows($qf) == 0){
		// if the number of lines exceeds 50% of the total, no line is returned,
		// the following query ensures that this does not occur
	$qf = mysqli_query($con, "SELECT * FROM table WHERE MATCH(f) AGAINST ('$dbf' IN BOOLEAN MODE)");
	if(mysqli_num_rows($qf) == 0){
			// echo "it's not matches  above 90%";
	}else{
		$percent = 0;

		while($row = mysqli_fetch_row($qf)){
			similar_text($row[2], $f, $percent);
			if($percent >= 90){
				$id = $row[0];
break;
			}
		}
	}
}else{
	
	$row = mysqli_fetch_row($qf);

	$percent = 0;
	
	similar_text($row[2], $f, $percent);

	if($percent >= 90){
		$id = $row[0];
}
}

Welcome to EE, chrisvee.  Here are some general guidelines to make your use of this site more enjoyable and productive for you...

At EE, the experts exchange answers and advice for points.  If you look at the questions awaiting answers in this zone, you will see a lot of 500 point questions.  Your question is competing for the experts' attention among those high-point questions.  So as a matter of simple economics you might be able to envision which questions will get the experts' attention first.   Just a thought.

We are experts, but not mind readers.  Inquiries that are broad, vague and hypothetical may not get answers that are as succinct and effective as inquiries that have actual URLs, complete code examples, and clearly expressed questions.  "It doesn't work" is not an error message.  Whenever possible, please provide the inputs and tell us what you want for the outputs.  An incredibly important concept is the SSCCE; please read the online page and embrace the SSCCE strategy.  If you do not have the SSCCE, stop what you're doing and create one, and post it with your question.  And please accept that sometimes the right answer is, "Don't do that -- it doesn't work that way."

If you want us to be able to share working code, we need you to show us where you have put your test data.  If you have no test data, please create some.  We do not want you to post "live" passwords and such.  Instead, please set up a testbed and show us the links to that, instead of the live data.

We answer questions and provide teaching examples, but we cannot build applications for you.  If you do not understand the basics of computer science and the programming languages involved in your applications, you might be better off to hire a developer.  Often a great deal of trial and error, plus a depth of knowledge and background information is necessary to get a piece of an application working.  The experts will try to help, but sometimes the only reasonable answer is, "Please read the fine manuals" or "Be respectful of your time; don't take a year learning information technology -- hire a professional developer and you'll get good results in a couple of weeks."

All of us who have been at EE for a while have seen questions like, "How do I do 'X' in 'Y' language, and by the way, I do not know anything about 'Y' language."  For some reason we never see anyone ask, "I want to play a piano sonata, and by the way, I have never taken piano lessons."  It is hardly a sin if you do not know a particular programming language -- I do not know most of them -- but it is not reasonable to expect that you will learn a programming language by asking questions in an online forum, any more than you could learn to play the piano by asking questions in an online forum.  Instead your best question might be, "What are good learning resources to get a foundation in 'Y' language?"  We are glad to help with that.

Here are some good learning resources for PHP.

The only thing I see wrong with the code snippet is that the last line should not be ?> (never use the close PHP tag if you can avoid it).  Instead it should be } to close the control structure.

You could do it like this as well - eliminating the superfluous second loop
<?php
$x = $_GET[x];
$con=mysqli_connect("example.com","peter","abc123","my_db");
$res =  mysqli_query($con,"SELECT * FROM text");
while ($row = mysql_fetch_assoc($res)) {
  if (similar_text($x, $y, $percent) > 90) {
    echo $row['text'] . "<br/>";
    // Save only strings > 90% here $string[] = $row['text']
  }
   // Save all strings here $string[] = $row['text'];
}
?>

html page collects fonts like above through javascript and sends it to php page. fonts are different for different browsers.but those are almost same in all browsers. we store fonts  mysql column.

 I want to find  similar fonts string($_GET)  with already stored fonts in database.

Normally WHERE clause is used to find exact match. But here in this case, return only above 90% matching.

nemws1Database AdministratorCommented:
You'd have to tokenize everything (meaning break things down to individual words), but you might be able to use SOUNDEX()

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_soundex

To find similar matches.  There's nothing that will easily give you a "90%" match. (Genetic pattern matching algorithms might let you specify a '.9' match, but there isn't anything that I know of in MySQL or PHP besides SOUNDEX() that can do "close" matches).

The test data looks a little garbled, but this will work for an example.  You can adapt it to your own data base.  Moving parts are at the end.

similar_text() in PHP!  Hmm.   Learn something new every day. :)

Ray PaseurCommented:
This might not work as expected... the return value is the matching character count.

if (similar_text($x, $y, $percent) > 90)

If you want a value greater than 90% matched, you would want to test the $percent variable.

At Experts-Exchange it is traditional to award points when you have exercised the volunteer community.  Now it seems that you want to close the question without awarding any points.

It is not our job to write working code for you (although you got several examples of working code here).  For that, you need to hire a paid professional developer.  Our role here in the EE community is to help you find answers to your questions.  I thought we did a pretty good job of that.

So what you're saying to us is that there was nothing here at all that helped you in any way?  You already knew all about similar_text()?  You already knew how to set up test data and simulate queries?
