Ensuring PHP substr Breaks Strings at Word Boundaries

When truncating strings using the substr function, it's important to ensure that the cutoff occurs at the end of a word, not in the middle of one. This is crucial for maintaining readability and conveying the intended meaning in text output.

To achieve this, you can utilize the following code:

substr($body, 0, strpos($body, ' ', 260))

In this snippet:

• substr() takes the string $body and selects a substring with the starting position 0.
• strpos() searches for the first occurrence of the space character (' ') within $body starting from position 260.
• The result of strpos() specifies the position where the substring should end, ensuring that the cutoff occurs at the first word boundary after 260 characters.
