A problem with strpos and strings that span multiple lines

[dmulyava]

Hi folks ...

 

I suspect that this will be a trivial question to the experts here, and you will be able to help me out.

 

I have been using a shared hosting account while developing my script, and now I have to move it to the production server.

 

One thing I realized, though, is that the test server was using PHP 4.4.6, and the new (production) server is using 4.3.9; There is something different between these two versions, or between the php_ini variables, that is throwing off how my scripts are using multiline strings.

 

Here is an example. Consider the following code. It opens an external website, reads it's contents into a variable. It then scans the variable for a string, and outputs it's location. On the test server - this page outputs 215. On the new server, nothing is echoed.. meaning that it did not find the string.

 

What should I be looking into? Thanks a big bunch! :thumbsup:

 

<?php
$c="";
$openurl="http://cnn.com";
$file = fopen($openurl,"r");
while(!feof($file))  $c .= fgets($file, 1024);
fclose($file);



$findme1 = '<meta http-equiv="refresh" content="1800">
<meta name="Description" content="CNN.com delivers the latest breaking news and information on the latest top stories, weather, business, entertainment';
$pos1 = strpos($c, $findme1);
echo $pos1;
?>

 

Have done some further poking around.. consider the code

<?php
$c="";
$openurl="http://cnn.com";
$file = fopen($openurl,"r");
while(!feof($file))  $c .= fgets($file, 1024);
fclose($file);

$findme1 = '<meta http-equiv="refresh" content="1800"><br>
<meta name="Description" content="CNN.com delivers the latest breaking news and information on the latest top stories, weather, business, entertainment, politics, and more. For in-depth coverage, CNN';
echo strrev($findme1);







?>

 

This code outputs the reverse of the string. The result? The "working" server returns:

NNC ,egarevoc htped-ni roF .erom dna ,scitilop ,tnemniatretne ,ssenisub ,rehtaew ,seirots pot tsetal eht no noitamrofni dna swen gnikaerb tsetal eht sreviled moc.NNC"=tnetnoc "noitpircseD"=eman atem< 
>rb<>"0081"=tnetnoc "hserfer"=viuqe-ptth atem<

 

The nonworking server returns

NNC ,egarevoc htped-ni roF .erom dna ,scitilop ,tnemniatretne ,ssenisub ,rehtaew ,seirots pot tsetal eht no noitamrofni dna swen gnikaerb tsetal eht sreviled moc.NNC"=tnetnoc "noitpircseD"=eman atem< 

>rb<>"0081"=tnetnoc "hserfer"=viuqe-ptth atem<

 

A blank line between the two lines!
