I am trying to write a PHP script that implements the MD5 algorithm just so that I can better understand MD5's inner-workings. For those of you already familiar with how MD5 works, could you help me figure out why my script is not producing the correct output? <?php $string = ""; $a = "01100111010001010010001100000001"; // 0x67452301 $b = "11101111110011011010101110001001";

OFXAdapter: Failed to parse request: Unable to parse an atomic field "OFXRequest.OFXRequest.SignOnMsgsRqUn.SignOnMsgsRqV1.SonRq.DtClient": field value "20101005091544.000[-4:EDT]" is not a valid (YYYYMMDDHHMMSS.XXX[gmt offset:tz name]) date. I am trying to put together some PHP code to use the OFX standard to communicate with my bank in order to download my recent transactions. The standard details that in the sign-on request, the date and time must be included in the format listed above. As you can see, I have the value in the exact same format as specified. So my question is this: is there something about GMT offset or TZ names that I am missing here?

UPDATE: I accidentally included the wrong lines in my first post. The values I am trying to obtain do not have the colon next to them as I previously alluded to. Sorry for the confusion. The actual values I am trying to obtain are listed below: "1,799,447" "2,505,648,676" and "570,552,255". These three values correspond to "Points Earned" "EXP Donated" and "Credits Given", respectively. I do not have access to the code that generates the text I am trying to sift through. What I'm doing is copying all the text on the page, dumping it into my own PHP script through a form and parsing through it. Here is the full text: Steve™ Points Earned 1,799,447 EXP Donated 2,505,648,676 Credits Given 570,552,255 Repair Points Donated 13,163 Posts Made 13,145 Members Recruited 306 Item Flow Item Amount Donated Given From Guild Net Change Byte 171 9 162 Mana 0 10,000 -10,000 Ruby Herb 0 5,000 -5,000 Syn 0 1,333 -1,333 Taistelu 900 800 100

I'm normally fairly proficient with PHP, but I haven't done any coding in quite a while, so I'm a little rusty. I have an entire page of text from which I need to extract a single value. Here is a small portion of the page in question: Total Rank: 128 Total Points: 4,978 Next Rank: 20 For instance, I need to extract the values "128" "4978" and "20" and store them in variables. These values change all the time, so I'm not sure what the best way to go about this is... maybe a regular expression ? If that's the case, I've never been too good with them, so any help would be appreciated.
