    To accomplish what you are trying to do, simply follow this example:

    $top_h_text_**I want to use $i here!**

    becomes

    ${"top_h_text_".$i}

    So you basically take the string you want (which should be the name of an existing variable) and wrap it with ${}

    If this is in fact WordPress, and your top_h_icon_ and top_h_text are in fact defined. This would be appropriate method for concatenation of your $i increment and the variables. This is how you join two parts to make a single string.

    Note that with WordPress and outputting dynamic variables, you should escape them.

    <?php
for ( $i = 1; $i < 4; $i++ ) {
    if ( $top_h_text_ . $i ) {
        ?>
        <li>
            <?php
            if ( $top_h_icon_ . $i ) {
                ?>
            <i class="<?php echo esc_attr( $top_h_icon_ . $i ); ?>"></i>
                <?php
            }
            if ( 'fa fa-envelope' === $top_h_icon_ . $i ) {
                ?>
            <a href="mailto:<?php echo esc_attr( $top_h_text_ . $i ); ?>"><span class="top_header_text"><?php echo esc_attr( $top_h_text_ . $i ); ?></span></a>
                <?php
            } else {
                ?>
            <span class="top_header_text"><?php echo esc_attr( $top_h_text_ . $i ); ?></span>
                <?php
            }
            ?>

        </li>
        <?php
    }
}
