How to shorten a string without slicing through a word while keeping within a character limit in PHP [duplicate]

Answer 1

I don't know php very well but here is how you can do it with approximative syntax

$total_length = 0;

$words = $whole_sentense->split(' ')

$word_index = 0

$final_sentense = ''

while($total_length + strlen($words[$word_index]) < 140)
{
  $final_sentense .= words[$word_index]
  $total_length += strlen($words[$word_index]
  $word_index++
}

return ($final_sentense)
