[PHP] Mcrypt Function - New to it
Hi there..some what a new programmer when it comes to all this. I'm
trying to encrypt some data and then decrypt it. It doesn't have to be
high bit encryption just something simple like 3DES. But I keep getting
it wrong. Any help would be greatful. Here's the piece of code:
$iv = mcrypt_create_iv (mcrypt_get_iv_size (MCRYPT_3DES,
MCRYPT_MODE_ECB), MCRYPT_RAND);
$key = md5("Secret Key");
$sample2 = "Hello";
$lockdata = mcrypt_encrypt (MCRYPT_3DES, $key, $sample2,
MCRYPT_MODE_ECB, $iv);
echo "$lockdata\n";
$text = mcrypt_decrypt (MCRYPT_3DES, $key, $lockdata, MCRPYT_MODE_ECB,
$iv);
echo "$text\n";

Re: [PHP] Mcrypt Function - New to it
Well now I have the Encryption problem figured out but when I try to
decrypt the information, I'm getting this error:
Warning: mcrypt module initialization failed in test.php on line 11
Here's Line 11:
$text = mcrypt_decrypt (MCRYPT_TripleDES, $key, $lockdata,
MCRPYT_MODE_ECB, $iv);
again any help would be appreciated.

Thanks. I got the issue figured out. There was an .htaccess file in the root of the website that I had forgotten about, it was affecting everything due to it's bad config.

[PHP] Search a flat file.
I want to be able to search a flat file line by line looking for data such as a username then display all the information in that line.

ok I believe I follow you on that, I will give that a try. But the
question I have now is how do I loop that request?

[PHP] Another Flat File question.
I know I've asked this before but I don't believe I asked the question correctly. I have a flat file database that is delimited with colons. This file will have new records added to it on a regular basis. What I want to do is be able to search that file based on a keyword that is inputted by a user, then it will search that database comparing each record for that value, if that value returns true, I want it to display the results of that record. How would I do this when I don't know the number of records that will be searched (since it will rise and fall almost daily)? Also, how would I create a dynamic array? I hope this makes sense to someone, I've been pulling my hair out on this. Thanks! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Include question
I'm trying to use the include function in some PHP scripts, but when I do include 'config.inc'; or include 'config.php; It returns all the information in the file when I look at my test php file (which calls the include) Anyone know why this is? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Include question
Yes, but according to http://www.php.net/manual/en/function.include.php I should be able to delcare the include and then pull the information out normally. So by what the manual says I can do this somefile.php callfile.php But when I just do It prints: $apple = 'green'; $pear = 'yellow': Why is that?

[PHP] Unlink question more or less
I want to use unlink() to delete a wildcard, but at the moment I keep getting parse errors. Here's what happening: I'm mucking around with some login stuff, when a user logs in it writes a flat file that collects some information about them, the flat file is created with the name username.dateyeartime Now each time they log in I want to delete that file and replace it with the new file that has the latest dateyeartime ending on it. I've tried unlink (username.*); but that returns an error. Is there a way for unlink() to recongize wildcards? If not how would I do this? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Unlink question more or less
Yeah they are, actaully I switched it to a static name and then added the time stamp as part of the information I'm gathering. Now I just re-write the file on each log in.

[PHP] Dynamic Arrays
I have an array question. I want to use a dynamic array but I don't know how to do this. What I want to do is this, I want to write a form script that takes the elements of the form and submits them in the array then I want to do a loop and check to see if each element in the array has a value and then if it does bullocks for them, but if it doesn't then I want it to come to a screeching halt and tell them what dolts they are for missing a field. So basically I want to have a Required field option for the form. I'm still learning arrays and dynamic arrays are just throwing me and I can't find a good code example to work from.

Re: [PHP] beginner in PHP
Try this:
echo "$catalog[unitprice]";
in my experience I've only been able to use the echo() without the
quotation marks if I'm calling a function, for variables you need the
quotation marks.
Hope this helps.

I have a quick question that I haven't been able to find the answer to yet. I've made a couple of guest books via PHP but the biggest problem I'm having is if any one inputs a ' or " or anything like that, the output in the book shows the stupid \ for the escape.
