How to store values from foreach loop into an array?

Closed 1 year ago.
Consider the following php code which is scraping a clients old static website for his customers emails...
$urls = explode(PHP_EOL, file_get_contents('urls.txt'));
print '<pre>'; print_r($urls); print '</pre>';
print '<strong>Results:</strong><br>';
function get_emails($url) {
$html = file_get_contents($url);
$dom = new DOMDocument;
#$dom->loadHTML($html);
$links = $dom->getElementsByTagName('a');
foreach ($links as $link){
$href = $link->getAttribute('href');
if (strpos($href, 'mailto') !== false) {
return str_replace("mailto:","",$href) . '<br>';
}
}
}
foreach ($urls as $key => $url) {
print get_emails($url);
}
I am reading a list of urls from urls.txt but the result is only the one of the last url in the file. All of the others are ignored. I had hoped it would return a nice list of all his customers urls so we can import them into the new site.
Can someone help diagnose the issue?

Answer 1

It's because of:-
return str_replace("mailto:","",$href) . '<br>';
It will terminate the execution of loop.
1. Either do:-
$urls = explode(PHP_EOL, file_get_contents('urls.txt'));
print '<pre>'; print_r($urls); print '</pre>';
print '<strong>Results:</strong><br>';
function get_emails($url) {
$html = file_get_contents($url);
$dom = new DOMDocument;
#$dom->loadHTML($html);
$links = $dom->getElementsByTagName('a');
foreach ($links as $link){
$href = $link->getAttribute('href');
echo str_replace("mailto:","",$href) . '<br>';
}
}
foreach ($urls as $key => $url) {
get_emails($url);
}
2. OR do like below:-
$urls = explode(PHP_EOL, file_get_contents('urls.txt'));
print '<pre>'; print_r($urls); print '</pre>';
print '<strong>Results:</strong><br>';
function get_emails($url) {
$html = file_get_contents($url);
$data = array(); //define array
$dom = new DOMDocument;
#$dom->loadHTML($html);
$links = $dom->getElementsByTagName('a');
foreach ($links as $link){
$href = $link->getAttribute('href');
$data[] = str_replace("mailto:","",$href) . '<br>'; //assign each value to the array
}
return $data;
}
foreach ($urls as $key => $url) {
print_r(get_emails($url));
}
