Importation of the information from an another's site on the site in the design

Importation of the information from an another's site on the site in the design. (By the example of importation of weather forecasts with Yahoo.)

Goods, sirs!

The example is intended for those who starts to work with php, and not only for them.

Result of job of the program (script) is weather forecast for 5 days for any city interesting you, deduced{removed} as which is pleasant to you, instead of to designers of the site - donor.

The information in such cases undertakes from known servers of weather forecast (where do not write a phrase " use of the information ", etc. is forbidden). In this case the server http://weather.yahoo.com on which there are pages with weather for rather plenty of cities is used, and practically always it is possible to find if not city interesting you, the nearest to him and identical on weather conditions.

It is the finished project working on a site http://sim-sim.ru in section of tourism " weather in the world ".

Unique lack is only that the administrator should enter into a text file (is possible{probable} the variant with mysql, but in that case it was easier to me to make in a file) the name of settlement on the native language and the link to page with weather forecast on him on JAkho server. But anybody for you will not do{make} it.

Therefore, the script will consist of 2 parts:

1. A file with administration (the name of city is entered in the first line, on the next line - the link). To assort job of the given part, I think, does not cost, more than it is enough comments.

2. A file with the program. Job of the program will be in detail described below.

1. Administration

We display the form with the password pass. In a window are entered: numbers{rooms} of the name of the link Then, after pressing the button and check of the password, we write down the new list in a file.

<html>

<head>

<title> admin weather </title>

</head>

<body>

<? php

$adr=$DOCUMENT_ROOT."/weather/weather.ini "; // the address of a file in which names of cities with links will enter the name

$password ='pass'; // unpretentious system of authorization

$eror ='Password eror! ';

$old=file ($adr); // it is readable that now is in a file

if ($submit) {// it is checked on nazhatost` buttons

if ($pass == $password) {

$fp=fopen ($adr, "w");

fwrite ($fp, $ini); // it is written down in a file the changed data

fclose ($fp);

$old=file ($adr);

}

else {

echo $eror;

}

<form method=post action = " <? php echo $PHP_SELF?> "> // the information entered into the form, is processed by the same file

password: <input type=text name=pass> <br>

inicialisation: <textarea name = "ini" rows=15 cols=60>

for ($i=0; $i <sizeof ($old); $i ++) {

echo $old [$i], " "; // we display the current variant of a file

}

</textarea>

<br>

</form>

</body>

</html>

After input of the information in a file as, we receive:

Larnaka

http://weather.yahoo.com/forecast/Larnaca_CY_f.html

Pathos

http://weather.yahoo.com/forecast/Paphos_CY_f.html

"44" - number{room} of city.

"Larnaka" - the name of city.

"http://weather.yahoo.com/forecast/Larnaca_CY_f.html" - the link to weather in the city of Larnaka on JAkhe.

Links to cities are organized by a principle:

<a href=http: // www.sim-sim.ru/catalogue/weather.php? weather=50> Larnaka </a>

And it is possible so:

<a href=http: // www.sim-sim.ru/catalogue/weather.php? city=Larnaka> Larnaka </a>

But if city from drukh words in blanks we write "%20"

In that case, numbers{rooms} of cities in the list are not necessary:

Larnaka

http://weather.yahoo.com/forecast/Larnaca_CY_f.html

Pathos

http://weather.yahoo.com/forecast/Paphos_CY_f.html

If at us not a text file, and mysql all is easier.
