PHP Regex to Remove http:// from string

Question 1

I have full URLs as strings, but I want to remove the http:// at the beginning of the string to display the URL nicely (ex: www.google.com instead of http://www.google.com)

Can someone help?

Question 2

$str = 'http://www.google.com';
$str = preg_replace('#^https?://#', '', $str);
echo $str; // www.google.com

That will work for both http:// and https://

Question 3

According to the documentation:

preg_match_all — Perform a global regular expression match

Since you are after just one, you should be using preg_match:

Perform a regular expression match

$regex = '/https?://[^" ]+/i';
$string = "lorem ipsum http://google.com lorem ipusm dolor http://yahoo.com/something";
preg_match($regex, $string, $matches);
echo $matches[0];

Yields:

http://google.com

Question 4

The Arabic regex is:

[u0600-u06FF]

Actually, ?-? is a subset of this Arabic range, so I think you can remove them from the pattern.

So, in JS it will be

/^[a-z0-9+,()/'su0600-u06FF-]+$/i

See regex demo

Question 5

(19|20)[0-9][0-9]

This will read in only 1900 and 2000 ranged dates.

Question 6

For this PHP regex:

$str = preg_replace ( '{(.)1+}', '$1', $str );
$str = preg_replace ( '{[ '-_()]}', '', $str )

In Java:

str = str.replaceAll("(.)\1+", "$1");
str = str.replaceAll("[ '-_\(\)]", "");

I suggest you to provide your input and expected output then you will get better answers on how it can be done in PHP and/or Java.
