Thanks! Your site was the first that came up in my search. This behavior is like in java when a variable simply contains a pointer to another variable such as

String s = “hello”;
String t = s;

t is simply pointing to the memory location of s and when you change the value of s, t points to s all the same and will return the same new value.

This is a site that lets you query source code of programming books with special characters like ‘&’.

Hey, thanks for the great tip. I’ve always wondered what the ampersand did. That will definitely be useful! Cheers

This is good to know. Google should have a way to find literal code like operators.

Shouldn’t the line:

&$ref = $original;

have the ampersand on the second variable?

$ref = &$original;

I recently installed PHP5.2.8 using EasyPHP 3.0 on an XP machine and have been trying to install PEAR in order to access its templates but I keep getting a warning that the “include_path defined in the currently used php.ini does not contain the PEAR PHP directory you just specified”.

However, even though I have changed the include_path in php.ini (which is located at C:\Program Files\EasyPHP 3.0\php) to “c:\Program Files\EasyPHP 3.0\php\pear”, I still keep getting the warning that the “Current include path is .;C:\php5\pear”.

I have looked all over and have not located the php.ini file on the C: drive with the path .;C:\php5\pear. I cannot imagine where the include path .;C:\php5\pear is being read from during installation.

I would appreciate it if someone could tell me where this path is being read from and how I can change it.

I need to access the PEAR templates to build my application.
