Skills Of The Trade

Skills
There are plenty of skills in the industry that I am certain that I need but do not have the skill in it at the moment.
The skills that I’m interesting in learning are Flash or PHP. Although looking at the industry jobs going at the moment PHP seems to be more valuable than Flash. A lot of this is to do with the fact that PHP is more accessible on the web than flash.

Reason
Flash: This is a skill, which I would like to know more about, because I know that it is used on a lot of websites these days and can also be used a lot to produce nice interactions on a site between the display and the user. However with this come some accessibility issues, with users having some problems clicking on slash links etc.

PHP: This skill is used on almost every modern day website. Usually to store information such as member (usernames and passwords) and also can be used to log IPS and other information. This skill seems to be needed in the industry, and usually is classes as standard.

Example Jobs

In the job above skills required are mainly Adobe products and also Flash. So this could be something to aim for, however this seems like more a designer role.

This job however is based on Networking. But you need a lot of knowledge in PHP and also a fair amount of PHP experience to even get a look in.

Another web design job, however this requires both Flash and PHP.

In my opinion both skills are important in the industry but I feel PHP seems to be more the industry standard, this is why I would like to do PHP for my self timed learning plan rather than Flash.
