PHP 7- String Manipulation

String Manipulation - Done. it was easy to understand, but i think i will need a cheat-sheet to remember all these functions especially because its not something you can use in your everyday coding.

I am looking forward to PHP 8 - create your own functions.

Done. Made sense.

String Manipulation can be very handy but I often catch myself getting carried away with trying to do to much and then I end up with a bunch of rubbish text so I try to just do the necessary without adding to many flourishes.

I've always wanted to run a script on my site to check what browser people are using and if it's anything below IE9 to print out that they have 10sec to upgrade or their PC will explode

Had no trouble with section 7.
Thank you Shadow for the cheet sheat

String manipulation almost done.

Changing case, trimmimg, shuffling & finding positions, splitting & joining lines and escaping certain characters done.

Before moving on to functions, I'll definitely revisit this part to explore the === operator:

... just in case the character you're searching for is at position 0,
one must use the triple equals operator ( = = = ), which checks for a value
and also what type of value it is: integer, string, Boolean, etc.

Done for today!

Found string functions very good, sure will use it often in the future, thanks for cheat sheet, will make them easier to use! The === is very insightful, but will need to read more about that operator.

Done and dusted

..&ru..

Managed to knock off chps 6 & 7 last weekend. I tried the findbrowser script on IE, FIREFOX, CHROME and it works fine with a few IF statements embedded. Arrays and string manipulation are very important part of programming, I have worked with them in other languages (COBOL, Fortran, Dbase,C..) in the past. Will be moving on 8,9,10 soon.

done. explode and implode similar to perl's split and join.

Quite interesting the Explode and Implode The find browser script was cool but didn't pick up my (Chrome) browser so edited the code and it did on to the next chapter.

The ucwords() function in PHP is amazing.
I've written my own functions in other languages to handle this kind of string manipulation.
The trim() function in PHP is also very useful.
Users often add trailing white spaces after the text they input.
The string position function can also be very useful.
In the example given the PHP scripts gets the browser name, converts it to uppercase.
The strpos() function gets the position of the uppercase browser name.
The if statement will print the name of the browser that was found.
I've always wondered what the explode() function does.
I've seen code snippets where the explode() function is used to build a twitter feed.
The str_word_count() function could be very useful.
I suppose it could be used to see how many words a person can type per minute.

This was a nice and easy going section.
str_shuffle() is such a fun function.

I also particularly liked this bit of code :

Language: PHP
 $agent = $_SERVER["HTTP_USER_AGENT"];
 print $agent;

Implode() and explode() have such nice names.

The bit on escaping was interesting too.

Very informative chapter.
I liked the browser script, and will stick to echo rather than print.

Done

I am using string built-in functions in order to validate some of the user inputs on the student registration form.
