For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
File and URL reading in PHP
In PHP, we say "there's a function to do that" as the answer to almost any question is going to be in the form of a function name, or a list of functions, to call. And PHP has more
functions than almost any other language, making it more flexible than most.
Take file handling ... where in so many other languages you have just got open
type constructs whereas in PHP you have those same constructs plus a whole lot of others
lets you read the whole contents of a file into an array
lets you read a file line by line and break in into an array of tokens
lets you read the whole of a file into a string.
Impressive range already? Then remember that you can also give an URL
as the first parameter when you open a file ... and that way the same set of functions allow you to read from another web page .... (written 2007-03-20, updated 2007-03-21)
