Wordpress functions.php有一个解析错误[重复]

Hi I ran into a prob while setting up the functions.php file for Wordpress. My localhost server is showing this error: Parse error: syntax error, unexpected 'if' (T_IF) in /Applications/MAMP/htdocs/wdnomads-wp/wp-content/themes/womendigitalnomads/functions.php on line 3

I've tried googling and pasting Wordpress' own code, but the error still exists. Not sure what I'm doing wrong.

<? php

    if ( ! isset( $content_width ) ) {
    $content_width = 660;
}

</div>

<? php should be <?php.

What exactly is your question?

Your formatting should have no space before php

Try out this, just replace your code with following code :-

function prefix_content_width() {
    $GLOBALS['content_width'] = apply_filters( 'prefix_content_width', 660 );
}
add_action( 'after_setup_theme', 'prefix_content_width', 0 );
