Description:
------------
This is the result of url like this : 

var_dump(parse_url("//example.com/web:o"));

==>
array(2) {
  'host' =>
  string(11) "example.com"
  'path' =>
  string(6) "/web:o"
}

but if I replace the :o with :1 the result is false 

var_dump(parse_url("//example.com/web:1"));
==> 
bool(false)

Also its correct if I use the large integer value : 

 var_dump(parse_url("//example.com/web:1232323232"));

==>
array(2) {
  'host' =>
  string(11) "example.com"
  'path' =>
  string(15) "/web:1232323232"
}



Test script:
---------------
<?php
//Correct:
var_dump(parse_url("//example.com/web:o"));
//Incorrect: 
var_dump(parse_url("//example.com/web:1"));
//Correct:
var_dump(parse_url("//example.com/web:1232323232"));


Expected result:
----------------
array(2) {
  'host' =>
  string(11) "example.com"
  'path' =>
  string(6) "/web:o"
}
array(2) {
  'host' =>
  string(11) "example.com"
  'path' =>
  string(6) "/web:1"
}
array(2) {
  'host' =>
  string(11) "example.com"
  'path' =>
  string(15) "/web:1232323232"
}



Actual result:
--------------
array(2) {
  'host' =>
  string(11) "example.com"
  'path' =>
  string(6) "/web:o"
}
bool(false)
array(2) {
  'host' =>
  string(11) "example.com"
  'path' =>
  string(15) "/web:1232323232"
}
