[SOLVED] Scraper and Preg Match

[atticus]

Hi all,

 

I have never used a scraper before, but I need to automate a process and this is where I am so far:

 

<?php
$data = file_get_contents('http://www.example.com/');
$regex = '/\/screenshots\/website-templates\/(.+?)-m/';
preg_match($regex,$data,$match);
var_dump($match);
echo $match[1];
?>

 

I am able to retrieve one piece of data with this script... I need it to grab all nine of the numbers and put it into an array...

 

Also, I am not sure how to pull data out of the array. Ideally, I want to run a while loop and insert each snippet of data into a database. Any ideas or sources I could work from...thanks in advance

changed preg_match to preg_match_all() which got all of the instances...still don't know how to use the data in the array as of yet.

based upon php.net, I used this code:

 

foreach ($match as $color) {
    echo "Do you like $color?\n";
}

 

Unfortunately, the output is only:

 

Do you like Array? Do you like Array?

<?php
foreach ($match[1] as $digit) {
echo $digit;
}
?>

 

Since $match[1] is an array of the first parenthesized matches. And if you're grabbing digits only, you can specify that in your pattern:

 

'~/screenshots/website-templates/([0-9]+)-m~'

 

By using another pattern delimiter we don't need to escape the slashes.

thebadbad beat me to it.

Atticus, note that when using preg_match_all, this automatically creates a multi-dimensional array.. so simply scanning the base array won't suffice.

Thanks guys...this really clears it up for me...I am able to now use my script! thanks.
