I was reading on a forum the other day about some benchmarks for PHP. The guy had posted some results in ms measurements, and was getting upset about his erratic results. There were some things that he was forgetting, however.
In our current setup at (“the triangle”), we have to use odbc connections to access our db2-udb database - and I don’t like it. But we have to stick with it - and that’s the way life is. The main reason I don’t like it is the immense overhead and time it takes to execute queries. Well, I did some research and found out some interesting things. The most important of which was a cursor setting that allowed me to gain up to 400% performance. Find out how:
The “security guys” have been talking about the problems with FireFox’s password manager and I got curious. It turns out that javascript can access saved passwords in your password manager simply by creating a login form and capturing the input field’s contents.
After listening to a javascript internals optimization talk, I wanted to see how these concepts could relate to PHP. The biggest thing that stuck out to me was the order of the for loops in javascript.
A lot of weird things have been happening ever since we introduced a new error handler at (“the triangle”). First of all, it took down our whole site for a good portion of time (oops!), then it created a large project for us to review our code. Turns out a lot of the errors were just weird little things that we ignored.
Everyone knows that standard SVN has its list of 6 or 8 standard hooks - but what if you’re 1) lazy, 2) busy, 3) don’t have access to the SVN server? Using one of the popular win32 shell integrated svn clients, TortoiseSVN, we can still force commit log messages easily:
I was looking at some code I had written about 3 years ago - how sad! I was creating a PDF of my resume using PHP to grab my qualifications out of a database. Unfortunately, I never researched into the header php command, so I made my job harder. Instead of writing it with a php file, I made a php file, and renamed it as a .pdf file. I modified my .htaccess file to process that one particular file as a php script. This way, the file executed as php but was mime/typed as the pdf.
I had a function in some of my code that I wanted to trigger a notice error on certain occasions. Unfortunately, it kept halting my script with a Warning instead. Unfortunately, the error handler at that particular block of code was not properly capturing the error string. It runs out that I was triggering an E_NOTICE instead of an E_USER_NOTICE error… (if I would have reviewed the trigger_error manual page, I wouldn’t have made this mistake… silly, lazy developer). Just to make sure that I fully understood this issue and hopefully wouldn’t make the same mistake again, I made a quick proof of concept:
When researching for my live error reporting posting, I tried running some exec and passthru command tests by starting up calc.exe. While they executed the command correctly, I got some weird results in my script … which I suppose now make sense. Let’s see how we can start programs in Windows, and not run into the same issues that I did.
