WordPress post excerpt section-wise (e.g., paragraphs, sentences, or words)

If you want to limit the WordPress post excerpt section-wise, you can divide it into specific sections (e.g., paragraphs, sentences, or words) and then display only a particular section or a limited number of sections.

Here's how you can achieve this:

Example 1: Limit Excerpt by Paragraphs

?

1 2 3 4 5 6 7 8 9 10 11 12 13

<!--php // Get the full excerpt $excerpt = get_the_excerpt();   // Split the excerpt into paragraphs $paragraphs = explode("\n", $excerpt);   // Limit to a specific number of paragraphs (e.g., 2) $limited_paragraphs = array_slice($paragraphs, 0, 2);   // Output the limited excerpt echo implode("\n", $limited_paragraphs); ?-->

Example 2: Limit Excerpt by Sentences

?

1 2 3 4 5 6 7 8 9 10 11 12 13

<!--php // Get the full excerpt $excerpt = get_the_excerpt();   // Split the excerpt into sentences using a period as a delimiter $sentences = preg_split('/(?<=[.?!])\s+/', $excerpt, -1, PREG_SPLIT_NO_EMPTY);   // Limit to a specific number of sentences (e.g., 3) $limited_sentences = array_slice($sentences, 0, 3);   // Output the limited excerpt echo implode(' ', $limited_sentences); ?-->

Example 3: Limit Excerpt by Words

?

1 2 3 4 5 6 7 8 9 10 11 12 13

<!--php // Get the full excerpt $excerpt = get_the_excerpt();   // Split the excerpt into words $words = explode(' ', $excerpt);   // Limit to a specific number of words (e.g., 20) $limited_words = array_slice($words, 0, 20);   // Output the limited excerpt echo implode(' ', $limited_words) . '...'; // Add "..." for indication ?-->

Explanation:

1. Paragraphs (explode("\n")): Splits the excerpt by new lines.
2. Sentences (preg_split): Uses a regular expression to split the excerpt into sentences based on punctuation.
3. Words (explode(' ')): Breaks the excerpt into individual words.

Use Case:

1. Use the paragraph-based approach for content with clear paragraph divisions.
2. Use the sentence-based approach for summaries or descriptive excerpts.
3. Use the word-based approach when you need precise control over the word count.

You can choose the method depending on how you want to display or limit the excerpt.
