Description:
------------
I want to introduce certain chinese text into a database. The SQL Query requires that all apostrophes are escaped.
Like "'" -> "\\'" .
As I want to process chinese and other languages that don't use latin characters I opted for a string replace with "mb_ereg_replace()".
I found that "mb_ereg_replace()" could replace latin character names within the Text and also apostrophes between latin character passages but was unable to do that when a chinese character was just before the apostrophes.
Like "位于't Goor Park" -> "位于\\'t Goor Park"
I tried to use this command to achieve this. On many texts it worked, but on this text it failed.
$srs = mb_ereg_replace("[\']", "\\'", $srs);

Curious was that I can detect the apostrophe with "mb_strpos()", but I can't replace it.
$iapops = mb_strpos($srs, "'");

Test script:
---------------
This Script shows that some passages can be replaces but that important apostrophe can't be touched, but yes it can be detected.

$iapops = mb_strpos($srs, "'");

if($iapops !== false)
{
  echo "apostrophe found on '$iapops'\n";

  echo "test 0: '$srs'\n";

  $srs = mb_ereg_replace("(goor)", "[GREEN]", $srs, "i");

  echo "test 1: '$srs'\n";

  $srs = mb_ereg_replace("[\']", "[apostrophe]", $srs);

  echo "test 2: '$srs'\n";

  if(mb_strpos($srs, "'") !== false)
    echo "replace failed!";

}  //if($iapops !== false)

Expected result:
