Limiting characters in $content

Hi there,

I have the following code which displays some content from a directory listing in WP. I would like to limit the number of characters that are displayed.

<?php

if ( ! defined('ABSPATH') ) {
	exit;
}

if ( empty( $options['info_fields'] ) ) {
	return;
} ?>

<!-- <ul class="lf-contact">-->
	<?php foreach ( (array) $options['info_fields'] as $info ) {
        $string = $info['label'];
        $attributes = [];

        if ( $is_caching ) {
            list( $string, $attributes, $cls ) = \MyListing\prepare_string_for_cache( $string, $listing );
        }

        $content = do_shortcode( $listing->compile_string( $string ) );
        if ( ! empty( $content ) ) { ?>
            <!--<li <?php echo join( ' ', $attributes ) ?>>-->
            	<?php if ( ! empty( $info['icon'] ) ): ?>
                	<i class="<?php echo esc_attr( $info['icon'] ) ?> sm-icon"></i>
            	<?php endif ?>
                <p><?php echo $content ?></p>
<!--            </li>-->
        <?php }
	} ?>
<!--</ul>-->

I have tried the following, but is then inserting the same content and from an entirely different post.

// Get the post content
$content = get_the_content();

// Define the maximum number of characters to display
$limit = 150;

// Trim the content to the desired character limit
$trimmed_content = wp_trim_words( $content, $limit, '...' );

// Output the trimmed content
echo $trimmed_content;
    

Any ideas how I can limit the characters on the above original code?

Many thanks!
