Why my php can't print out the string I input?

Here is the code I input...

mysql_query("INSERT INTO test (string) VALUES ('tes><ssst')");    

And this is how I query the result out:

$result = mysql_query("SELECT * FROM test");     

while($row = mysql_fetch_array($result))
  {
  echo $row['id'] . " ----开发者_JAVA技巧 " . $row['string'];
  echo "<br />";
  }   

but I only get this result:

3 ---- tes>

I miss the missing part: "<ssst", but when I go to the db, I can retrieve the string I inserted. What's happen? Thank you.

That's because your browser thinks <ssst is an html tag. You should encode your output

while($row = mysql_fetch_array($result)) {
  echo $row['id'] . " ---- " . htmlspecialchars($row['string']);
  echo "<br />";
} 

use htmlspecialchars to encode output
