i'm still new to php and programming and was hoping to get some help on
a few questions i haven't had success in answering myself. I
successfully created my first very simple script to accomplish a task I
wanted, but not completely. see my code below:
<?php
//my first ever php program simply designed to automatically adjust new
prices of my properties
//current property prices
$prices = array('250000', '250000', '350000');
//percentage of how much to add to current prices
$increase_rate = '0.015'; // 1.15 %
//add new percentage to each price
foreach ($prices as &$newprice) {
$newprice = $newprice + ($newprice * $increase_rate);
}
//print out all new prices
for ($key = 0; $key < 3; $key++) {
print "$prices[$key]<br />";
}
?>
(forgive me if these questions seem completely common sense or stated
clearly in the php manual. I have done reading into these all day and
have gave up and so here I am)
HELP QUESTIONS:
---------------
1.) How would I make a copy of the old prices array that
was manipulated?
e.g. -> echo the following structure:
set an array of values, then do a function to
manipulate the values, then show the old
values in comparison of the new values
(basically, show that $253,750 used to be
$250,000)
2.) a) What if i have commas in my prices by default?
e.g. = array('349,502' '234,995');
b) How would I go about processing comma values
received via a form that a user entered or from .CSV
file that looked like (132,500, 123,340, 345,959,
244,459)?
c) How would I add a comma into my printed outputed values?
3.) There must be a better way to print out all the values
from an array but constructing a loop came to mind and
beats doing it one by one. Is there better way?
