How to escape quotes in php

$name = "khan's";
$name = htmlentities(str_replace("'", "\'", $name));
echo $response = "<img src=\"images/action_delete.gif\" onClick=\"confirmDelete('" . $name . "')\"/>";

?>

php to encode special characters but not html tags

For Latin-1 you can escape characters easily with:

$html = preg_replace('/[\x80-\xFF]/e', '"&#x".dechex(ord("$0")).";"', $html);

For UTF-8 it's a bit more involving:

$html = preg_replace_callback("/(?!\w)\p{L}/u", "xmlent", $html);
function xmlent($m) {
    $str = mb_convert_encoding( $m[0] , "UCS-2BE", "UTF-8");
    return "&#x" . bin2hex($str) . ";";
}
