Answer 1

Utilizing substring to make a smaller string with the last position of " ".

substr($s1, 0, strripos($s1," "));

With a sample code:

$s1 = "ABC Hospital (rawalpindi)";
$s2 = "ABC Hospital (New) (Rawalpindi)";
$s3 = "XYZ Hospital (old) (Lahore)";

echo substr($s1, 0, strripos($s1," "));
echo substr($s2, 0, strripos($s2," "));
echo substr($s3, 0, strripos($s3," "));

This will produce the output:

ABC Hospital
ABC Hospital (New)
XYZ Hospital (old)
