you can use a reference parameter to accumulate values like this.
function read_array($in, &$accumulator) {
$out = array();
foreach(file($in) as $str) {
$str = trim($str);
//some modifications
$out[] = $str;
//OR $all_str .= $str
$accumulator[] = $str;
// or $accumulator .= $str;
}
return $out;
}
Now after you call the function the last parameter will hold all of the
new values, this is a nasty way though and I would suggest you read some
more about
references(http://au2.php.net/manual/en/language.references.php).
You can ofcourse use a global variable to store this aswell if it was
an OO based thing (don`t use global keyword if your not using OO dear
god please!).
+1 for marking this as bogus, bad programming practice should not a
language make :)

Description:
------------
It's not a bug, it's a new language operator suggestion. When I use
other languages and PHP it's often were a one task - return values from
function. I suggest a new operator and a don't know any analogs in other
languages (may be I now small count of languages).
Reproduce code:
---------------
Task - return values from function with accumulating of results. For
example, when we read strings from file and want return array of this
strings (may be modified) from function we must accumulate/collect all
values in array or in string:
function read_array($in) {
$out = array();
foreach(file($in) as $str) {
$str = trim($str);
//some modifications
$out[] = $str;
//OR $all_str .= $str
}
return $out;
//OR return $all_str
}
It's a very often task. And may be it's will be useful for programers
have two new operators - for strings and for arrays, that accumulate
values within all function body and at the end return ALL
strings/elements automatically.
For example:
function read_array($in) {
foreach(file($in) as $str) {
$str = trim($str);
//some actions
return_array $str;//accumulate $str to internal temporary
array, that will be returned at the end of function
}
}
And "return_string" for strings temporary buffer.
