Inserir dado de célula Google Spreadsheet no PHP

[crola 0]

Estou tentando inserir dados de células do Google Spreadsheet no meu php para preencher o texto do HTML, contidos no arquivo page.php do Wordpress. Mas não sei como fazer, alguém saberia me ajudar?

<?php // The default template for displaying pages ?>

<?php get_header(); ?>

<div class="bnt-container">

    <div class="content content-page">
        <main class="site-main">

            <?php 
            // Start the Loop
            if ( have_posts() ) { 
                while ( have_posts() ) { 
                    the_post(); 
                    // Include the page content
                    get_template_part( 'content', 'page' );     

                    // If comments are open or the page has at least one comment, load the comments template.
                    if ( comments_open() || get_comments_number() ) {
                        comments_template();
                    }

                // End the Loop
                } 
            }

            ?>
            <?php
function gpus_scripts(){
    wp_enqueue_script( 'projagnt-script', get_template_directory_uri().'/includes/js/proj_agnt.js', array('jquery'), false, false );
    wp_enqueue_script( 'projagnt-script', get_template_directory_uri().'/includes/isotope/isotope.pkgd.js', array('jquery'), false, false );
}

add_action( 'wp_enqueue_scripts','gpus_scripts');?>
<?php global $post; ?>
<?php if(is_page('Project')){ ?>

                <div id="cellA1_text">...</div>
                <div id="cellA2_text">...</div>
                <div id="cellA3_text">...</div>
                <div id="cellA4_text">...</div>                            
<?php } ?>

        </main>
    </div>
