Re: [PHP] Re: GD - dynamic PNG generation
I managed to fix my problem, it seems that it was taking so long because of the consturction of a for loop of mine. I was calling the ImagePNG function too early, menaing it seemed to take forever to execute. it's now running at a fraction of it's original time.

[PHP] another GD question
two in two days, i must look like a real retard. anyway, i'm having another problem with GD now, it seems that when i create my image, if i specify too many pixels i.e. imagecreate(600, 2290) it will not create the image, just a blank file it's sort of hard to explain, but i'll try. i am currently reading in a html file, which i want to display as an image. I read in my HTML and strip it of all HTML tags, this is stored as a varaible. i now explode this string using every occurence of a new line (\n), into an array, this gives me an array of lines. I now want to format the text a little bit, because I dont want my lines to be too long, so i word wrap it to 40 cols, followed by a rtrim, just to remove any chars that will appear in the image that i dont want. i then pass this array into my imageMake method. i create my image, using imagecreate, now, for my x value, i set it to be 500, and i set my y value to be 1963(i'll explain why in a minute). i then execute a for loop, which runs through each of the elements of the array(each line of text) and runs the GD ImageString function, this will take an incrementing value, making sure that each new line is below each other. when the for loop is completed, i call ImagePNG and then ImageDestroy. I suppose I should mention that I am creating a seperate image, and not displaying it imediattly. anyway, so long as I keep the Y value of the imagecreate function below 1963 the image will be created, but not all of the text is dispayed, since there seems to be more lines of text than area displayed.. if it is larger than that, all i get is a blank image, and if i try opening it in an image viewer i get an error. i have a feeling that it is someway related to the size of my text set, i.e. it is currently 216 lines long(after i perform the word wrap on it). also, if I run the exact same code on the same text formatted differntly (HTML removed, wordwrapped all done in pre-processing) it seems that I am able to increase the Y value in the imagecreate function, but, I still cannot raise it so far as to be able to include all of the text. this seems very strange, and I was wondering if anyone else has encountered this problem before. i'm not sure if i've made myself too clear here, if you have any questions, fire away. sorry for the long post Conor -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Very interesting and challenging question
I had something like this to do a couple of months back, unfortunately, my code was deleted by someone smart in my office. But i can pretty much remember the algorithim behind it. What I done was read in my file into a buffer, then use the explode function, i think, or something like it, basicially there is a function that allows you to parse a string using a set number of char as the delimiters, e.g. first item = first 10 chars etc, i think i was able to differentiate the number of chars, e.g. 10 for the first item, maybe 15 for the second and so on. I then read them all into an arry. once in the array it's a piece of cake, I know which item in the array corresponds to which field from the original file, e.g. item 1 = row 1 col 1, item 2 = row 1 col 2, item 5 = row 2 col 1 (assuming there are 4 cols). At this point you can just loop through the array inserting the fields into the database, or whatever you want to do. I cant remember what happens when I had empty fields. I think I may have had to fill in all blank fields for some reason. I'm not sure if this makes any sense. But I hope it's been a help.

[PHP] (another, not entirely)sessions question
Hey there, I'm currently writing a web app using php. I was just looking for some advice on one aspect. On this site, users will be able to log in and post messages, or articles, or replies etc, you get the idea. Anyway, I am storing some info about the users, the usual stuff, name, email, password, all in mysql. I am also storing other info, such as when they last posted, and how many times they have posted. When a user posts a new message, the message is sent to mysql and stored in a table, at the same time, i also have to increment their total number of posts. The way this is done is by selecting the posts field on their userid, which i have to find using their username, which is set as a session var, when the user logs in. This all results in a good few queries to mysql. I was wondering would it be better to load all the user info, e.g. number of posts, last post date, into session vars, or should i set a cookie on the client side, or should i just continue with the queries.

[PHP] xml and php question
Hey all I'm not so sure if this is the correct place to ask this question, but I'm hoping some of you will be able to give me some feedback. I am currently toying around with php and mysql developing a website for myself, the current one is partly php powered, but I am trying to move it over to a complete php and mysql system, I would also like to use XML. i have previously used Xml on another web project, and i really liked the way you could reformat you content, and it's ease of use. What i was wondering is, if any of you use XML to store your content, in what way do you go about it. At the moment i see 2 sepeerate ways of going about it. a)Mark up your documents in xml and store the xml documents in a database, your database can be pretty simple, witha couple of fields that represent some of the meta data in the xml file, e.g. Author, Date-created, then a large blob which is the doc. when you wish to view the document, you search on the criteria that is available, and then retrieve your xml doc. Some down sides to this could be the explosion in the size of the db, if you are storing a large amount of documents etc and also the redundancy in some of hte fields, e.g you have an author field, but this info is contained in the xml doc. It is good, because it is an essentialy simple application, in both php code to pull the data and in the database design. b)have the database act as a sort of XML holder, e.g. break the document down to it's base components, and store all the meta data in the database, when a doc is needed, the xml doc can be created on the fly, by pulling the data out of the appropriate fields. some problems with this can be the database design, it can become extremly complicated(i would imagine, i have not tried it yet), as you are effiectively modelling the DTD in the database. but at the same time, we are reducing redundancy, hopefully, so long as it is well normalised. the reason i am asking this is becaue of the amount i read about xml, how good it is extensible etc, there is not much out there inregards to the practical application of it, aside form the odd tutorial on how to construct a DTD or how to parse XMl with Java/PHP etc. once again, i'm not sure if this post is appropriate to this mailing list, perhaps i should send it to a MySql list or something, but if anyone has any ideas or thoughts on the topic i would really appreciate it. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
