I see some strange results with strpos() function...
echo strpos("naše republika", "a"); // 1
echo strpos("naše republika", "š"); // 2

I have got this php code
$Likes=1112;
$Likes=$Likes/1000;
echo $Likes."k";
This code returns me 1.112k,but my goal is to get 1.1k
Use the number_format function:
echo number_format($Likes,1)."k";
And a coding style advice: don't start your variables with an upper case letter!

How do I count comma-separated values in PHP?
(5 answers)
Closed 9 years ago.
$string = "oidjdssd , odi,jdois, 3089u,, oisdjsd";
How do i find out if theres more than 3 commas in the string above in the best way?
I would suggest substr_count. You can see if the result is >3 to see if there's more than three.
echo count_chars($string)[ord(',')];
Or for PHP<5.4
$chars = count_chars($string);
echo $chars[ord(',')];
BTW: As it seems, that you are handling CSV-data, you should have a look at str_getcsv()
