This is a sample of the string of data that i need to extract the price of.

"Price Rs 475 000 - CHEVROLET AVEO LS // SEP 11 6,000 kms - Red.. full options.. MANUAL 5 door // hatchback Contact me on 786 8394"

I have many such strings after crawling a particular website and there can be any number or words in the string.

I have tried to separate each word by a space and store it in the array $arr. I have declared another array for storing identifiers of price $arrPrice. if the word price or rs is found,then the data (eg 475 000) is stored in the variable $price. However as i have exploded it with space, it is not taking into consideration the 000 . I am getting only 475 in the xml tag.

The efficient way of doing it may be with regex,but i am not good at it. Grateful if someone could help me.

Find Below my codes till now,

Thanks!

<?php


    foreach($html->find('div.field-content') as $e) {//find the h3 element that contains class field content


    $arrPrice = array("rs", "price","rs."); // an array of identifiers to retrieve price

    $str = $e->innertext;// crawled data from a website
    $str = strtolower($str); //converting string to lower case
    $arr = explode(" ", $str);//creating an array of the string by seperating it from the spaces

    if (strlen($str) > 0) {
        $price='';

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

            //finding price 
            for ($j = 0; $j < sizeof($arrPrice); $j++) {
                if ($arr[$i]==$arrPrice[$j]) {
                    $price = $arr[$i+1];
                    //echo 'Price='.$arr[$i+1];

                }
            }   

        }
        $xml.="<Cars>";
        $xml.="<Price>".$price."</Price>";
        $xml.="</Cars>";
    } 

    else {
        echo "String is blank";
    }


}

$file = fopen('data.xml','w');
if(!$file) {
    die('Error cannot create XML file');
}
fwrite($file,$xml);
fclose($file);
?>

get html code of the url, paste it here, then we can try some regex on it for price

to be noted that the information is dynamic, that is it keeps changing

this sounds diffcult to pick right amount, because format is not fixed.

yeah thats the point. i cant find a way to do that /// HELP!

any how if we write some code, but you can not be sure, that it will pick right amount.
do you have any other website source with better html display elements?

I have to use a website where a user enters his information the way he wants, for example if he wants to sell his car,he can put it in the following format: rs 410000 / rs. 410000/ rs 410 000/ price rs 410 000 / rs 410k .. as u can see there are several ways of writing it,but i have to extract the value only that is 410000 without the space.
even if i take another website, the way i have to ecxtract the price will still be same.
