PHP - Easy ? Display Array Values

helllo dear php-commmunity


new to Ruby - i need some advices -

i plan to do some requests in osm-files. (openstreetmap)

Question - how can i store the results on a Database -
eg mysql or - (if you prefer postgresql) -

note: my favorite db - at least at the moment is mysql


here the code

    require 'open-uri'
    require "net/http"
    require 'rexml/document'
     
    def query_overpass(object_type, left,bottom,right,top, key, value)
       base_url = "http://www.overpass-api.de/api/xapi?"
       query_string = "#{object_type}[bbox=#{left},#{bottom},#{right},#{top}][#{key}=#{value}]"
       url = "#{base_url}#{URI.encode(query_string)}"
       resp = Net::HTTP.get_response(URI.parse(url))
       data = resp.body
       return data
    end
     
    overpass_result = REXML::Document.new(query_overpass("node", 7.1,51.2,7.2,51.3,"amenity","restaurant|pub|ice_cream|food_court|fast_food|cafe|biergarten|bar|bakery|steak|pasta|pizza|sushi|asia|nightclub"))
     
    overpass_result.elements.each('osm/node') {|x|
      if !x.elements["tag[@k='name']"].nil?
        print x.elements["tag[@k='name']"].attributes["v"]
      end
      print " | "
     
      if !x.elements["tag[@k='addr:postcode']"].nil?
        print x.elements["tag[@k='addr:postcode']"].attributes["v"]
        print ", "
      end
      if !x.elements["tag[@k='addr:city']"].nil?
        print x.elements["tag[@k='addr:city']"].attributes["v"]
        print ", "
      end
      if !x.elements["tag[@k='addr:street']"].nil?
        print x.elements["tag[@k='addr:street']"].attributes["v"]
        print ", "
      end
      if !x.elements["tag[@k='addr:housenumber']"].nil?
        print x.elements["tag[@k='addr:housenumber']"].attributes["v"]
      end
      print " | "
      print x.attributes["lat"]
      print " | "
      print x.attributes["lon"]
      print " | "
      if !x.elements["tag[@k='website']"].nil?
        print x.elements["tag[@k='website']"].attributes["v"]
      end
      print " | "
      if !x.elements["tag[@k='amenity']"].nil?
        print x.elements["tag[@k='amenity']"].attributes["v"]
        print " | "
      end
      puts
    }

look forward to hear from you

again - i would love to store it on a mysql - database - if possible. If you would prefer postgresql - then i would
takte this one.... ;-)

well - i guess that the answer to this will be the same no matter what language we are using.
If the db is a sql database we need to design the database schema and create the tables in the database.

The first step in accessing a db in our code is to get a connection to it.
If ruby is our choice of language, a search for "ruby sql connector" will give us
lots of options to read about.

Well - we also can do it in PHP. What do you think!?

Next, based on the schema we have designed, we need to create queries suitable for storing the data.
We will likely need to consider our transactional model.

Again, searching "ruby sql transactional model" will give us plenty of food for thought. Finally, we may want or need to close the connection to the database.

i have a dictionary  - THIS IS obviously a python dictionary

an this has approx 8 000 lines with records


[/CODE]

$ python printer.py
{'url': 'http://www.site1_com' 'cname': 'butcher', 'name': 'cheng', 'email': 'mail1@hotmail.com'}
{'url': 'http://www.site2_com' 'cname': 'dilbert', 'name': 'James', 'email': 'mail2@hotmail.com'}

[code=auto:0]i have a mysql-db up and runing in my opensuse

there i have created a db with the fields

url
cname
name
email



i use the

import MySQLdb

i studied this documentation he http://stackoverflow...abase-in-python

but i think this goes a bit over my head.


- well how can i get the data  ( in other words the dictionary) into the database?

love to hear from you

greetings

Hi all,

I'm a first time poster here and I would really appreciate some guidance with my latest php challenge! I've spent the entire day googling and reading and to be honest I think I'm really over my head and need the assistance of someone experienced to advise the best way to go!

I have a multi dimensional array that looks like (see below); the array is created by CodeIgniter's database library (the rows returned from a select query) but I think this is a generic PHP question as opposed to having anything to do with CI because it related to working with arrays.

I'm wondering how I might go about searching the array below for the key problem_id and a value equal to a variable which I would provide. Then, when it finds an array with a the matching key and variable, it outputs the other values in that part of the array too.

For example, using the sample data below. How would you recommend that I search the array for all the arrays that have the key problem_id and the value 3 and then have it output the value of the key problem_update_date  and the value of the key problem_update_text. Then keep searching to find the next occurrence?

Thanks in advance, as above, I've been searching really hard for the answer and believe i'm over my head!

Hello everyone,

I have been trying several things,recently, and I can't figure out how to get a series of numbers, grouped together as a string of number, instead of it adding or grabbing the last number that was randomly generated.

I'm wanting to save it in a variable (of course), so I can pass it though a query when it is needed.


foreach($array as $number){
echo $number;
}


$array is the variable where it is an array but all the randomly generated numbers are stored there.

All / any help would be gratefully appreciated.

Lets start out by saying I'm a nube to sql/php things so I am learning as I go. I try to read all that I can before I post, and only post when I cant figure it out on my own.

That being said. What I want to do in simplest terms is be able to assign a variable to each item in an sql table. So say I have an mysql table that has ID, username, fontcolor. I want to be able to pull those out so say....


while($row = mysql_fetch_array($users)) {

$username[$i] = $row[username];
$fontcolor[$i] = $row[fontcolor];
}


Then on the page I can just call to $username[1] type thing. I have tried mixing this several different ways with for and while and I keep getting errors on the page. I realize the code isn't showing everything but its just there to show you the idea of what I'm trying to do. I just want it to generate a list(array) that will make it easier for me to call back just the items I need on parts of the page with out having to have extra coding everywhere.

Thanks in advance.

Jim
