Keep in mind this code will return only one client, i also suppose max health is 100HP, so i putted 101 in min.

PHP Code:

new client = HasLowestHealth() 


PHP Code:

HasLowestHealth()
{
    new min = 101
    new client, health
    
    for(new i = 1; i <= MaxClients; i++)
    {
        if(IsClientInGame(i) && IsPlayerAlive(i))
        {
            health = GetClientHealth(i)
            
            if(health < min)
            {
                min = health
                client = i
            }
        }
    }
    
    return client
}
