I need to extract the dollar amount e.g. $594 from the meta title of an URL. I am getting full meta title however i just need the $594 from it not the whole title. Here is my code. Thanks

<?php 

 

// Web page URL 

$url = 'https://www.cheapflights.com.au/flights-to-Delhi/Sydney/'; 

 

// Extract HTML using curl 

$ch = curl_init(); 

curl_setopt($ch, CURLOPT_HEADER, 0); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

curl_setopt($ch, CURLOPT_URL, $url); 

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 

 

$data = curl_exec($ch); 

curl_close($ch); 

 

// Load HTML to DOM object 

$dom = new DOMDocument(); 

@$dom->loadHTML($data); 

 

// Parse DOM to get Title data 

$nodes = $dom->getElementsByTagName('title'); 

$title = $nodes->item(0)->nodeValue; 

 

// Parse DOM to get meta data 

$metas = $dom->getElementsByTagName('meta'); 

 

$description = $keywords = ''; 

for($i=0; $i<$metas->length; $i++){ 

    $meta = $metas->item($i); 

     

    if($meta->getAttribute('name') == 'description'){ 

        $description = $meta->getAttribute('content'); 

    } 

     

    if($meta->getAttribute('name') == 'keywords'){ 

        $keywords = $meta->getAttribute('content'); 

    } 

} 

 

echo "$title". '<br/>'; 

?>

My Answer:
To extract the dollar amount from the meta title, you can use regular expressions to search for the pattern "$XXX" in the title. Here's an updated version of your code that extracts the dollar amount from the meta title:

php

// Web page URL
$url = 'https://www.cheapflights.com.au/flights-to-Delhi/Sydney/';

// Extract HTML using curl
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

$data = curl_exec($ch);
curl_close($ch);

// Load HTML to DOM object
$dom = new DOMDocument();
@$dom->loadHTML($data);

// Parse DOM to get Title data
$nodes = $dom->getElementsByTagName('title');
$title = $nodes->item(0)->nodeValue;

// Parse DOM to get meta data
$metas = $dom->getElementsByTagName('meta');

$description = $keywords = '';
for($i=0; $i<$metas->length; $i++){
$meta = $metas->item($i);

if($meta->getAttribute('name') == 'description'){
$description = $meta->getAttribute('content');
}

if($meta->getAttribute('name') == 'keywords'){
$keywords = $meta->getAttribute('content');
}
}

// Extract dollar amount from title using regular expression
preg_match('/\$(\d+)/', $title, $matches);
$dollarAmount = isset($matches[1]) ? '$' . $matches[1] : '';

echo "$dollarAmount" . '
';

?>


This code uses the `preg_match` function to search for the pattern "$XXX" in the title and extract the dollar amount. The extracted dollar amount is then stored in the variable `$dollarAmount` and echoed out.
