Question

i’ve seen in many forums that they cut the url from the center and add 3 dots if it’s long in order to shorten it.

Example: ajaxify multipart encoded form (upload forms) —Will be—> http://stackoverflow.c…ed-form-upload-forms

How to do that using pure php?

Thank you

e.g. via preg_replace()

$testdata = array(
  'http://stackoverflow.com/questions/1899537/ab',
  'http://stackoverflow.com/questions/1899537/abc',
  'http://stackoverflow.com/questions/1899537/abcd',
  'http://stackoverflow.com/questions/1899537/ajaxify-multipart-encoded-form-upload-forms'
);

foreach ($testdata as $in ) {
  $out = preg_replace('/(?<=^.{22}).{4,}(?=.{20}$)/', '...', $in);
  echo $out, "\n";
}

prints

http://stackoverflow.com/questions/1899537/ab
