Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

You are overwriting $this->s['a'] in the first iteration of foreach to a1e. And as 
in a1e there's no %s, it remains unchanged in further iterations.

Description:
------------
class a{
	public $s = array('a' => 'a%se');
	
	function aa(){
		foreach(range(1,5) as $v){
			$this->s['a'] = str_replace('%s', $v, $this->s['a']);
			var_dump($this->s);
		}
	}
}

$a = new a();
$a->aa();


result always:

array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}

i think right:
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a2e"
}
array(1) {
  ["a"]=>
  string(3) "a3e"
}
array(1) {
  ["a"]=>
  string(3) "a4e"
}
array(1) {
  ["a"]=>
  string(3) "a5e"
}



Test script:
---------------
class a{
	public $s = array('a' => 'a%se');
	
	function aa(){
		foreach(range(1,5) as $v){
			$this->s['a'] = str_replace('%s', $v, $this->s['a']);
			var_dump($this->s);
		}
	}
}

$a = new a();
$a->aa();


result always:

array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}

i think right:
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a2e"
}
array(1) {
  ["a"]=>
  string(3) "a3e"
}
array(1) {
  ["a"]=>
  string(3) "a4e"
}
array(1) {
  ["a"]=>
  string(3) "a5e"
}



Expected result:
----------------
class a{
	public $s = array('a' => 'a%se');
	
	function aa(){
		foreach(range(1,5) as $v){
			$this->s['a'] = str_replace('%s', $v, $this->s['a']);
			var_dump($this->s);
		}
	}
}

$a = new a();
$a->aa();


result always:

array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}

i think right:
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a2e"
}
array(1) {
  ["a"]=>
  string(3) "a3e"
}
array(1) {
  ["a"]=>
  string(3) "a4e"
}
array(1) {
  ["a"]=>
  string(3) "a5e"
}



Actual result:
--------------
class a{
	public $s = array('a' => 'a%se');
	
	function aa(){
		foreach(range(1,5) as $v){
			$this->s['a'] = str_replace('%s', $v, $this->s['a']);
			var_dump($this->s);
		}
	}
}

$a = new a();
$a->aa();


result always:

array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a1e"
}

i think right:
array(1) {
  ["a"]=>
  string(3) "a1e"
}
array(1) {
  ["a"]=>
  string(3) "a2e"
}
array(1) {
  ["a"]=>
  string(3) "a3e"
}
array(1) {
  ["a"]=>
  string(3) "a4e"
}
array(1) {
  ["a"]=>
  string(3) "a5e"
}
