Endre litt på et ferdig rss reader script


Anbefalte innlegg

Hei

 

Lurte på om noen vet hvor i koden jeg kan legge inn en for-løkke slik at den skriver ut et x antall nyheter og ikke alle som denne ferdigscripten gjør.

Har prøvd litt selv uten å ha klart det, og php kunnskapene mine er det så så så med...

 

 

<?php

/* PHP RSS Reader v1.1

By Richard James Kendall

Place the URL of an RSS feed in the $file variable.

 

The $rss_channel array will be filled with data from the feed,

every RSS feed is different by by and large it should contain:

 

Array {

[TITLE] = feed title

[DESCRIPTION] = feed description

[LINK] = link to their website

 

[iMAGE] = Array {

= url of image

[DESCRIPTION] = alt text of image

}

 

[iTEMS] = Array {

[0] = Array {

[TITLE] = item title

[DESCRIPTION] = item description

[LINK = a link to the story

}

.

.

.

}

}

 

By default it retrives the Reuters Oddly Enough RSS feed. The data is put into the array

structure so you can format the information as you see fit.
