$string = '1100225,Lakshmin,pkrrrr College,"PKRRRRR University, Choice",nandhaaaaa,"Nandhaa University, Kumali"';

$string = preg_replace_callback(
        '|"[^"]+"|',
        create_function(
            // single quotes are essential here,
            // or alternative escape all $ as \$
            '$matches',
            'return str_replace(\',\',\'*comma*\',$matches[0]);'
        ),$string );
$array = explode(',',$string);
$array = str_replace('*comma*',',',$array);
print_r($array);       
exit;

What encoding does it assume the string to be in? – Tammitammie

the preg function got a u modifier to set UTF8, see php.net/manual/en/reference.pcre.pattern.modifiers.php other function are binary-safe – Saltarello

create_function in php 7.2 is deprecated. Is there any solution about it? thank you in advance – Faggoting
