How to truncate a string to the first n characters of a string and add three dots if any characters are removed with PHP?
To truncate a string to the first n characters of a string and add three dots if any characters are removed with PHP, we can use the substr function.
For instance, we write
$string = strlen($string) > 13 ? substr($string, 0, 10) . "..." : $string;
to call substr with $string to return a new string that has the characters in $string from index 0 to 9.
We return the string returned by substr if the $string‘s length is bigger than 13.
We get the length of $string with strlen.
Otherwise, we return $string.
Conclusion
To truncate a string to the first n characters of a string and add three dots if any characters are removed with PHP, we can use the substr function.
