if the trailing slash is left off urls when using fopen(), file() etc, php doesn't open the location.

eg:

[mini:pgl]:~/public_html/test $ cat fopen.php 
#!/usr/local/bin/php -q
<?
$loc = 'http://www.php.net/';
if ($fp = fopen($loc, "r")) echo "opened file\n";
?>

[mini:pgl]:~/public_html/test $ ./fopen.php 
opened file

but:

[mini:pgl]:~ $ cat fopen.php 
#!/usr/local/bin/php -q
<?
$loc = 'http://www.php.net';    // no trailing slash
if ($fp = fopen($loc, "r")) echo "opened file\n";
?>

[mini:pgl]:~ $ ./fopen.php 
<br>
<b>Warning</b>:  fopen("http://www.php.net","r") - Undefined error: 0 in <b>./fopen.php</b> on line <b>3</b><br>

same with file():

[mini:pgl]:~ $ cat file.php 
#!/usr/local/bin/php -q
<?
$loc = 'http://www.php.net/';
echo count(file($loc));
?>

[mini:pgl]:~ $ ./file.php 
531

take away the trailing slash:

[mini:pgl]:~ $ ./file.php 
<br>
<b>Warning</b>:  file("http://www.php.net") - Undefined error: 0 in <b>./file.php</b> on line <b>3</b><br>
1

[mini:pgl]:~ $ /usr/local/bin/php -v
4.0.6
