I need a system that identifies the word with the # inside a text and adds it to a table.
And another system that identifies the word with # within a text, however, when it appears in the div, the word is linked.
Example of initial text:
#Stackoverflow people are great at # programming.
It turns into:
The staff at #Stackoverflow are great at # schedule
If the target is just the accents common in Portuguese, it is easy to list them one by one. I would make a regex with the following blocks:
A-Za-z case not accented áàâãéèêíïóôõöúç ñ: accentuated vowels of Portuguese, cedilla and others of lambuja, lowercase ÁÀÂÃÉÈÊÍÏÓÔÕÖÚÇÑ : accentuated vowels of Portuguese, cedilla and others of lambuja, upper case
spaces Therefore:
/^[A-Za-záàâãéèêíïóôõöúçñÁÀÂÃÉÈÍÏÓÔÕÖÚÇÑ ]+$/
Or, leaving the lowercase / uppercase distinction for the implementation:
/^[a-záàâãéèêíïóôõöúçñ ]+$/i
So to use with 0-9, a-z, A-Z and with accents:
<?php
$text = "O pessoal do #Stackoverflow são ótimos em #programação.";
$text = preg_replace('/(?<!\S)#([0-9a-zA-ZáàâãéèêíïóôõöúçñÁÀÂÃÉÈÍÏÓÔÕÖÚÇÑ_]+)/', '<a href="http://meusite.com/hashtag/$1">#$1</a>', $text);
echo $text;
?>
