HTML Parsing to Php array

iassael

Hello i want to parse the stats table from wunderground to a PHP table array,
what would be the best day to do this?
Thank you!

"Best" is subject to a lot of variables, but pending more information, I'd probably look into using the [man]DOM[/man] extension to parse the page and then gather the desired details. Alternatively, you could just grab the page into a single string (e.g. via [man]file_get_contents[/man]) and hack away at it with [man]PCRE[/man] functiond and other string functions to grab the desired data.

which would be the easiest way?
is there a tutorial or a book for more help on this subject? 🙂
thanks!!!

I'm not sure which is easier, as they are rather different approaches and it might depend on what sort of experience you have with object-oriented code (DOM) or regular expressions (PCRE). I don't know of any tutorials off-hand, though if you google for something like "php screen scraping" you may find something useful. And don't forget this forum's search facility, too. 🙂

I'd probably go the DOM route myself, just because it's...oh, I don't know...more elegant?

😉 thanks!
one more question i used this

<?php
include('simple_html_dom.php');

// Create DOM from URL or file
$dom = file_get_dom('http://www.wunderground.com/cgi-bin/findweather/getForecast?query=larisa');

// Find all <img>
foreach($dom->find('span[pwsvariable=humidity]') as $humid)
echo $humid->value . '%<br>';

$dom->clear();
unset($dom);
?>

how could i make it write what it found to an array table called $humid

foreach($dom->find('span[pwsvariable=humidity]') as $humidity) {
    echo $humidity->value . '%<br>';
    $humid[] = $humidity->value;
}
