How to count a particular word appearing in a text? 1

[aas1611]

Hi,

Let's say I have the following string/text:

$text= "new day new problem.";

How can I count the word "new", how many time it appears? (In this case, it appears 2 times).

It could also be two words, like "new day". In this case it appears once.

Please remember, that $text consists of several paragraphs.


Thanks!

Have you tried the [blue]substr_count()[/blue] The PHP online manual at php.net says this about it:

substr_count() returns the number of times the needle substring occurs in the haystack string. Please note that needle is case sensitive.

example:

$text = 'This is a test';
echo substr_count($text, 'is'); // 2

it finds the substring "is" 2 times in the original string.

----------------------------------
Ignorance is not necessarily Bliss, case in point:
Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

Great, it works...!

However, how would it be, if a case insensitive was necessary?

using the same function (and this is ugly) and borrowing vacunita's post you could do

$text = 'This is a test';
echo substr_count(strtoupper($text), strtoupper('is')); // 2
