Okay... I'm a PHP noob but I have a good background in C++ and Python... Now all I want to do is iterate through the following file, and appending all products to an array, with information stored inside the array for each product, then return it... here is the file:
-
// ../docs/products.txt
-
-
// This document is for displaying all your products
-
// To do this, there is a special format to create each offer.
-
// The format is as follows:
-
// [Unique Product ID]
-
// name=<name>
-
// description=<description>
-
// price=<price as pounds.pence e.g. 19.99 is £19.99>
-
// image=<image directory from ../images/products>
-
// extras=special or popular... If it's both then display it via a comma... special,popular... This is only if the product is either a special or a popular product. If it doesn't have any, put none

name=Green Laser Pen
-
description=This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength....
-
price=39.99
-
image=1.jpg
-
extras=special,popular
-
-
[2]
-
name=Cheese
-
description=A cheesy gadget
-
price=13.37
-
image=cheese.jpg
-
extras=none
-
Here is the function
[PHP]
<?PHP
function getAllProductDetails()
{
$arrayDetails;
$contents = file("docs/products.txt");
$productNum = 0;
foreach ($contents as $line_number => $theData)
{
if (str_replace(" ", "", $theData) && !substr($theData, 0, 2) == "//")
{
if (ereg ("[[][0-9]*[]]", $theData))
{
$productNum = (int)str_replace("]", "", str_replace("[", "", $theData) );
$arrayDetails[$productNum];
}
else if ($productNum)
{
$equalPos = strpos($theData, "=");
$arrayDetails[$productNum][substr($theData, 0, equalPos)] = substr($theData, equalPos + 1);
}
}
}
return $arrayDetails;
}
function getAllExtras( $extra )
{
$arrayList = getAllProductDetails();
$theArray;
if ($arrayList)
{
foreach ($arrayList as $key => $value)
{
if (strstr($value["extras"], $extra))
{
$theArray[$key] = $value;
}
}
return $theArray;
}
else
{
echo "Crap";
$theArray["name"] = "NULL";
$theArray["image"] = "1.jpg";
$theArray["description"] = "NULL DESCRIPTION";
$theArray["price"] = "13.37";
return $theArray;
}
}
?>
[/PHP]
Here is the code that calls that function
[PHP]
<?php
$arrayList = getAllExtras( "special" );
$randPos = array_rand($arrayList);
$randomSpecial = $arrayList[$randPos];
echo "<div class='picture'>";
echo "<img src=images/products/".$randomSpecial['image']." />;";
echo "</div>";
echo "<div class='text'>";
echo "<h1>".$randomSpecial["name"]."</h1>";
echo "<p>".$randomSpecial["description"]."</a>";
echo "<p>".$randomSpecial["price"]."</p>";
echo "</div>";
?>
[/PHP]
The end product ends up like
this which doesn't look right :( Please help me if you can...
Oh yeah, I did manage to get this working in python with the following code:
-
def getAllProductDetails():
-
arrayDetails = {}
-
f = open("D:/College Work/college/unit 21/website/docs/products.txt", "r")
-
l = f.readlines()
-
f.close()
-
l = ''.join(map(lambda x: x.replace('\r','\n'), l)).split('\n')
-
productNumber = 0
-
p = re.compile('[[][0-9]*[]]')
-
for line in l:
-
if line.replace(' ','') and not line.startswith('//'):
-
m = p.match(line)
-
if m:
-
product = int(line.replace('[','').replace(']',''))
-
arrayDetails[product] = {}
-
else:
-
eqPos = line.find('=')
-
if eqPos:
-
arrayDetails[product][line[:eqPos]] = line[eqPos + 1:]
-
return arrayDetails
-
I tried to create the equivalent of my PHP code in python, and it worked.. I'm lost, I've been at this for hours... I thank you in advance
