PHP Error while trying to install wordpress

I am trying to install wordpress to an old site that hasn’t been used for ages. This is what I get :Error: PHP is not running
WordPress requires that your web server is running PHP. Your server does not have PHP installed, or PHP is turned off.

>

prepare( “SHOW TABLES LIKE %s”, $wpdb->esc_like( $wpdb->users ) ); $user_table = ( $wpdb->get_var( $sql ) != null ); // Ensure that Blogs appear in search engines by default. $blog_public = 1; if ( isset( $_POST[‘weblog_title’] ) ) { $blog_public = isset( $_POST[‘blog_public’] ); } $weblog_title = isset( $_POST[‘weblog_title’] ) ? trim( wp_unslash( $_POST[‘weblog_title’] ) ) : ”; $user_name = isset($_POST[‘user_name’]) ? trim( wp_unslash( $_POST[‘user_name’] ) ) : ”; $admin_email = isset( $_POST[‘admin_email’] ) ? trim( wp_unslash( $_POST[‘admin_email’] ) ) : ”; if ( ! is_null( $error ) ) { ?> …and so on.

Would be appreciated if anyone could help me.
