In order to use newlines with the echo command pass the -e flag

echo -e "hi\nmom"

here’s a few functions that are required by some of my code / functions.

make_db_connection

function make_db_connection($conn_name, $conn_sql)
{

global $site_access, $database_site_access;

$covert_this_str = "global \$" . $conn_name . " ;";
eval($covert_this_str);
$covert_this_str = "\$" . $conn_name . "= mysql_query(\$conn_sql,\$site_access ) or die(mysql_error());";//report_error(‘002′,’" . addslashes($conn_sql) . "’));";
//echo $conn_sql."<br />";
eval($covert_this_str);
// addKill($conn_name);
}

fixForDB

function fixForDB($item,$nonEmpty=0){

$item=trim($item);
if(empty($item)){

$item=$nonEmpty;

}

if(isNaN($item)){
$item=”‘”.addslashes($item).”‘”;
}

return $item;
}

isNaN
this isn’t a function of mine. I found it on the php.net manual site. if you wrote it, please let me know so i can give proper credit

function isNaN( $var ) {
return !ereg (“^[-]?[0-9]+([\.][0-9]+)?$”, $var);
}

here is the code for a Proof of concept i did a few months ago. Its a demo ffmpeg and ffmpeg-php video conversion system that will also generate thumbnails. you either upload a file to the server (for large files) or select the file to upload (small files).

the code is offered as is. Please note this is a first version POC so the code is choppy and theres functionality missing, probably also alot of beta testing code.

*update: wordpress converts some of the characters into invalid code, so download / copy the source file here
http://elsid.net/wp-content/uploads/2007/10/ffmpeg_convert.php.txt

*update: the file works on php5, on at least it did when i tested. change the folder / url path to whatever your using.

you can view the source below

<?php
//error_reporting(2047);
//setup directory vars
$url_dir = "/video-convert-alpha/";
$url_folder="uploads";
$upload_dir = realpath($url_folder)."/";//"";
$url_dir="http://".$_SERVER['HTTP_HOST'].$url_dir.$url_folder."/";

//echo "uploads : ". $upload_dir;
function time_stamp()
{
return gmdate("YmdHis");
}
///my trusty old upload function
function upload_from_form($file_item)
{
global $_FILES, $upload_dir, $url_dir;
//echo "uploading<br>";
if (!empty($_FILES[$file_item]['name'])) {
//echo $_FILES[$file_item]['tmp_name'];

if($_FILES[$file_item]['size']*1==0){
echo "File : ".$_FILES[$file_item]['name']." is either empty or exceeds the file size limit, please reduce the size of this document, check the file, or contact Greg to increase the limit";
return "%";
}else{

$file_name = str_replace(" ", "_" , $_FILES[$file_item]['name']);
$file_name = str_replace("’", "_" ,$file_name);
$file_name = str_replace("\\", "_" ,$file_name);
$file_name = str_replace("#", "_" ,$file_name);

$file_name = str_replace("=", "_" ,$file_name);
$file_name = str_replace("|", "_" ,$file_name);
$file_name= time_stamp() . "_" . $file_name;

if (!file_exists($upload_dir . $file_name)) {
$file_loc = copy($_FILES[$file_item]['tmp_name'], $upload_dir . $file_name);
} else {
$file_name = time_stamp() . "_" . $file_name;
$file_loc = copy($_FILES[$file_item]['tmp_name'], $upload_dir . $file_name);
}
if ($file_loc != false) {
$file_loc = $upload_dir . $file_name;

return $file_loc;
} else {
echo "Could not find file : ".$_FILES[$file_item]['name'];
return "%";

} }
} else {
echo "upload failed<br>";
return "%";
}

Out of all the xml-rpc functions / classes etc out there i like this one the best. Why? its simple.

I’ll post a rewrite/ extended version once i get to it.

# Using the XML-RPC extension to format the XML package
$request = xmlrpc_encode_request(“weblogUpdates.ping”, array(“Copenhagen Ruby Brigade”, “http://copenhagenrb.dk/”) );

# Using the cURL extension to send it off,
# first creating a custom header block
$header[] = “Host: rpc.technorati.com”;
$header[] = “Content-type: text/xml”;
$header[] = “Content-length: “.strlen($request) . “\r\n”;
$header[] = $request;

$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, “http://rpc.technorati.com/rpc/ping”); # URL to post to
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 ); # return into a variable
curl_setopt( $ch, CURLOPT_HTTPHEADER, $header ); # custom headers, see above
curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, ‘POST’ ); # This POST is special, and uses its specified Content-type
$result = curl_exec( $ch ); # run!
curl_close($ch);

echo $result;

if your updating your path and would like to activate the changes right away do . /etc/profile

a quick echo $PATH will display your updated path

So i bought my 8 gig nano, nike+, arm band, and modded my shoes.

Why you ask? Simple because then I’d be forced to think about running, hopefully to one day lead up to me actually running…. So far that theory has worked once, for 1 mile.

That mile kicked my ass. It was all uphill in the blistering sun, during a snow storm.

So much for being proactive

< ?php
echo ‘

My Nike+ Stats’;
get_nikePLUS();
