PHP Website Email and WhatsApp Scraper Tutorial

In this tutorial we will build a simple but powerful PHP script that reads a list of websites from a text file and automatically extracts email addresses, WhatsApp numbers and phone numbers from those websites.

This type of script is useful for building contact databases, research projects, or collecting publicly available contact information from company websites.

The script works by reading a file containing URLs, opening each website using cURL, scanning the HTML for email patterns and WhatsApp links, and saving the results to another file.

Features of the Script

Reads website URLs from a text file
Automatically opens each website
Extracts email addresses
Extracts WhatsApp numbers
Extracts phone numbers
Processes websites in batches to avoid server timeout
Saves results to a new file
Works on most shared hosting servers

Required Files

Create a folder on your server and place the following files inside it:

index.php
scan.php
functions.php
jata.txt
results.txt

Sample Input File

The file jata.txt contains your data including the website URLs.

Company ABC | https://example.com
Company XYZ | https://example.org
Travel Agency Japan | https://agency.co.jp

File 1: index.php

This file creates a simple control panel to start the scanning process.

<?php
$total = 0;

if(file_exists("jata.txt")){
$lines=file("jata.txt");
$total=count($lines);
}
?>

<h2>Website Contact Scraper</h2>

<p>Total websites in file: <?php echo $total; ?></p>

<a href="scan.php?start=0">Start Scanning</a>

<br><br>

<a href="results.txt">Download Results</a>

File 2: scan.php

This script processes websites in batches to prevent server timeout.

<?php

include "functions.php";

set_time_limit(0);

$start = isset($_GET['start']) ? intval($_GET['start']) : 0;

$limit = 20;

$lines = file("jata.txt");

$total = count($lines);

$end = min($start+$limit,$total);

echo "<h3>Scanning $start to $end</h3>";

for($i=$start;$i<$end;$i++){

$line = $lines[$i];

$url = get_url($line);

$email="";
$wa="";
$phone="";

if($url){

$html = get_page($url);

if($html){

list($email,$wa,$phone)=extract_contacts($html);

}

}

$newline = trim($line)."|EMAIL:$email|WHATSAPP:$wa|PHONE:$phone\n";

file_put_contents("results.txt",$newline,FILE_APPEND);

echo "Processed $url <br>";

}

$next = $end;

if($next < $total){

echo "<script>
setTimeout(function(){
window.location='scan.php?start=$next';
},2000);
</script>";

echo "Continuing automatically...";

}else{

echo "<h2>Scanning Completed</h2>";

}

File 3: functions.php

This file contains the scraping functions that extract contact information from the website HTML.

<?php

function get_url($line){

if(preg_match('/https?:\/\/[^\s|"]+/i',$line,$m)){
return $m[0];
}

return "";
}

function get_page($url){

$ch=curl_init();

curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_TIMEOUT,10);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch,CURLOPT_USERAGENT,"Mozilla/5.0");

$html=curl_exec($ch);

curl_close($ch);

return $html;

}

function extract_contacts($html){

$email="";
$wa="";
$phone="";

if(preg_match('/[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}/i',$html,$m)){
$email=$m[0];
}

if(preg_match('/wa\.me\/([0-9]+)/',$html,$m)){
$wa=$m[1];
}

if(!$wa && preg_match('/api\.whatsapp\.com\/send\?phone=([0-9]+)/',$html,$m)){
$wa=$m[1];
}

if(preg_match('/\+?[0-9][0-9\-\s]{8,15}/',$html,$m)){
$phone=$m[0];
}

return [$email,$wa,$phone];

}

Running the Script

Upload all files to your server and open the following URL in your browser:

https://www.yoursite.com/scraper/

Click the Start Scanning link. The script will process about 20 websites at a time and continue automatically until all websites are scanned.

The extracted email addresses, WhatsApp numbers and phone numbers will be saved in the file results.txt.

Tips for Better Results

Ensure the input file contains valid URLs
Do not scan too many websites at once
Always respect website terms of service
Use the script only for publicly available information

Conclusion

This simple PHP website crawler demonstrates how to extract contact information such as email addresses and WhatsApp numbers from websites automatically. With further improvements, the script can also extract social media links, company details and location information.
