Very interesting again. Done

I have a problem with files. I just cant get my head around them. I have no problems using databases.

thank you Shado. my problem will be remembering the whole process of working with files. its mainly because i have never used them ever in my programming life. I always thought Databases are superior and modern.

thank goodness there is no exam for this course

I actually had a client once who was looking to upgrade their software from a program built with Access '97. I suggested PHP but they decided to go for some guy who suggested a 3rd party client built with C, etc. so the clients didnt have any idea what the power of PHP was and how effective it would be to move all of your internal software to a browser.

Long story short, the guy they hired then contacted be, because they couldnt get into the Access databases that was created with all the client's software in it. Apparently, the previous guy who built it never gave any passwords and had his own idea of data security (Youll run into that a lot lol). So what i did was crack through the password protected files, but the entire DB was encrypted. I got a lot of data, but the only way I could get it was in .CSV format.

Thanks to most of the processes discussed in this section though, I could import all of the data (32,500 customers with over 100,000 records linked.) with relative ease. Because all of the primary keys and unique keys were still in tact in the table I could set up a script to convert the data to a more manageable format which I could give back to the client.

Of course they had no idea the amount of crap they caused so the effort was never really appreciated. This ifc is the next problem most programmers run into:"Hi there can you please code something similar to facebook for me, but I cant pay you you can get 3% of the company"

Hope this was a decent scenario in which working with files in PHP could be used

Lol Wilco, I feel your pain

We also had a client that wanted a facebook website - we told him he should buy facebook then never the less we build him something similar albeit in a different colour.

Hahahahah!! I think we in the IT industry get some of the weirdest requests from time to time. My best one to contribute, was a user contacting our department and saying that they did not have MS Office 2010 installed on their PC. Went there and the program was installed. Querying the user about this, he said that he thought it was not installed cause there was not Word and Excel icons on the desktop...

Finally finnished with section 10.

Hi there all, done with this section too, lots of fun! Again think I know too little about security issues, would like to know more. Found that this link didn't work on php10p8: http://www.ilovejackdaniels.com/security/writing-secure-php/3/
but think it's been moved here if I'm not mistaken, so I thought I'd post the link here in case someone else is also interested: http://www.addedbytes.com/articles/writing-secure-php/writing-secure-php-3/
Cheers

Working with files done - also date and time functions. Will start with MySQL tomorrow evening.

Should be interesting.

This chapter was great, always thought, if i use databases to store my info, why then files???....so I knw can make an app with a function stored in another file, and i use it by using the "include" function, a great discussion was ventured into text files, php and CSV files...Chapter done

..&ru..

done. similar file functions to c's stdio

Being able to read text files can be very useful.
I guess if you are storing very little information in the text file, it can be quite efficient.
Instead of a database with lots of tables, you can use a text file in place of a database table.

Thanks for the link 77929284 .

Completed the section.
fgetcsv() - seems useful to be able to turn your whole file into an arrays.

Great section on working with files. This is definitely a useful one. Straight up and done.

hi guys,

I am on the topic "writing to files in PHP". I have tried to run the script in the example on the page from "HomeandLearn" but my safari browser is giving me these errors:

Warning: fopen(testFile.txt) [function.fopen]: failed to open stream: No such file or directory in /Applications/XAMPP/xamppfiles/htdocs/myPHP/practice1/work2/writingFiles.php on line 3
Warning: fwrite() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/myPHP/practice1/work2/writingFiles.php on line 6
Warning: fclose() expects parameter 1 to be resource, boolean given in /Applications/XAMPP/xamppfiles/htdocs/myPHP/practice1/work2/writingFiles.php on line 7
file created and written to

I have been thinking, is it my version of PHP? (If it is, how do i check my PHP version?). Or, what could it be that i'm doing wrong?

Thanks guys!

where did you save your file?

My file is saved as stated in the warning. According to HomeandLearn, the file to open (fopen) a is supposed to be created if not present.

Language: PHP
<?PHP
 
$file_handle = fopen("testFile.txt", "w");
$file_contents = "Some test text";
 
fwrite($file_handle, $file_contents);
fclose($file_handle);
print "file created and written to";
 
?>

You can have a look-see at the topic "writing files in PHP" from HomeandLearn...

Done

XAMPP cannot create the file in that directory, maybe permission issues e.g. Win7? Best to install in C:/XAMPP. That cod eis correct.
