Suppose a string contains "includ- ing" or "joi- ing". How would you search for and join hyphenated words in a string?


You could use a regular expression with preg_replace():
preg_replace('/-\s+/', '', $string);
This looks for a - followed by one or more whitespace characters and replaces them with the empty string.


// -- Get an array of words splitted with '- '
$splitted = explode('- ', $word);
// -- Rejoined words:
$joined = implode('', $splitted );

I'm going through sprintf() and other string formatting functions, but I have been unable to find an exact solution for stripping certain types of characters from a string. I wrote a function for this purpose (which seems quite nasty and not at all worth sharing here) but I am sure there is a easier way for what I am looking for.
$var = "abc244$%!";
now I want to format it this way:
$alpha = some_function($var); // alphabets only
$num = some_function($var); // numbers only
$alpha2 = some_function($var); // alphabets and special characters, no numbers.

To strip everything except numbers, use this:
$allnums=preg_replace("/[^0-9]/","",$var);
For all letters:
$letters=preg_replace('/\PL/u', "", $var);
For special chars:
$specialchars=preg_replace("/[a-zA-Z0-9]/", "", $var);

I want a regex that will help me to get the 4 numbers before the cc.
The RegEx must contain the cc to identify these exact number.
Example:
1600cc

You should use:
/(\d{4})cc\b/
\b ensures that "cc" is at the and of the word.

preg_match('/(\d{4})cc/', $string, $match);
$match[1] will contain the number.

preg_replace("/[^0-9]/", '', $Phone);

Ive been hunting online and cant seem to find anything explaining the extra "/+"

The following matches anything that's not a digit.
/[^0-9]/
The following matches anything that's not a digit, /, or +:
/[^0-9/+]/

I would like a regular expression in PHP to find all HTML entities such as "<br /> <br /> ..etc. " in order to remove them from a long string.

This one removes alpha, decimal and hex HTML entities:
$text = preg_replace('/&(?:[a-z\d]+|#\d+|#x[a-f\d]+);/i', '', $text);

Try using this regex... the [^\s]* one was capturing a whole lot other nonsense...
$text = preg_replace("/&(?:[a-z0-9]{2,8}|#[0-9]{2,3}+);/i", '', $text);

Try using strip_tags function, regex is not necessary here
