Description:
------------
Please compare this 3 script :
1. Simple Open a Page (everything going well)
<?
$buf = "";
$fp = fopen("http://poxy.x0.com/deai/html/index.html", "r");
if($fp) while(!feof($fp)) $buf.=fread($fp, 1024);
echo $buf;
?>

2. Simple Open A Page and eliminate the line break (THE PAGE CUT IN
MIDDLE)
<?
$buf = "";
$fp = fopen("http://poxy.x0.com/deai/html/index.html", "r");
if($fp) while(!feof($fp)) $buf.=fread($fp, 1024);

$buf = ereg_replace("\r|\n", "", $buf);
echo $buf;
?>

3. Open page using File and eliminate line-break per array elements
(everything going well)
<?
$buf = file("http://poxy.x0.com/deai/html/index.html");
foreach($buf as $key=> $value) {
$buf[$key] = ereg_replace("\r|\n", "", $buf[$key]);
}
$buf = implode("", $buf);
$buf = ereg_replace("\r|\n", "", $buf);

echo $buf;
?>

Reproduce code:
---------------
<?
$buf = "";
$fp = fopen("http://poxy.x0.com/deai/html/index.html", "r");
if($fp) while(!feof($fp)) $buf.=fread($fp, 1024);

$buf = ereg_replace("\r|\n", "", $buf);
echo $buf;
?>

Expected result:
----------------
the page without break line

Actual result:
--------------
half of the page without break line

It seems the way to read the page into $buf doesn't
matter. Just a bug in ereg_replace() as simply
replacing it by preg_replace() worked.


<?php
$buf = file("http://poxy.x0.com/deai/html/index.html");
$buf = implode("", $buf);
$buf = ereg_replace("\r|\n", "", $buf);

echo $buf;
?>

This also gives a wrong result.

The following code just doesn't work:

<?php
echo ereg_replace("a", "a", "abc\0def\0");
?>

Because inserted null bytes (¥x00) prevents it from
properly concatenating substrings delimited by the
replacement.

dunno if this is a limitation of ereg_* though.

It's yet another ereg_* limitation: Just use PCRE instead.
