1st file in my working machine is 
--------------------------------- 
<? 
require ("http://targetDomain/test_remote.php"); 
testPr(); 
?> 

2nd file on targetDomain(other machine) is 
------------------------------------------ 
<? 
echo("this is test_remote.php"); 
function testPr() { 
echo("remote : testPr()"); 
} 
?> 

When I execute 1st file, it prints out : 
---------------------------------------- 
this is test_remote.php 
Fatal error: Call to undefined function: testpr() 
in 1st file on line 3 


I know that the 1st file required the 2nd file successfully because it printed out the echo statement of 2nd file. 
However I cannot understand why it cannot use the function of the remote file.
