Extracting Twitter hashtag from string in PHP

Question

I need some help with twitter hashtag, I need to extract a certain hashtag as string variable in PHP. Until now I have this

$hash = preg_replace (\"/#(\\\\w         


        

Answer 1

Here's a non Regex way to do it:

<?php

$tweet = "Foo bar #hashTag hello world";

$hashPos = strpos($tweet,'#');
$hashTag = '';

while ($tweet[$hashPos] !== ' ') {
 $hashTag .= $tweet[$hashPos++];
}

echo $hashTag;

Demo

Note: This will only pickup the first hashtag in the tweet.
