You should pass the destination string to charsmax in string functions, not the source string. Also, you can remove the return PLUGIN_HANDLED in the if statement since the one immediately follows it outside of the if-else statement.

PHP Code:

public cmdGetArgs(id)
{
    new args[ 32 ];
    
    read_args( args , charsmax( args ) );
    remove_quotes( args );

    if( strlen( args ) > 31 )
    {
        client_print( id , print_chat , "You cant do that" );
        client_cmd( id , "messagemode SetArgs" );
    }
    else
    {
        copy( PlyrArgs[ id ] , charsmax( PlyrArgs[] ) , args );
    }
    
    return PLUGIN_HANDLED;
}
