Extract URLs from the website is used in many cases, generating a sitemap from website URL is one of them. You can easily get all URLs from a web page using PHP. Here we’ll provide short and simple code snippets to extract all URLs from a web page in PHP.<\/p>\n

The following PHP code helps to get all the links from a web page URL. The file_get_contents()<\/code> function is used to get webpage content from URL. Fetched web page content is stored in $urlContent<\/code> variable. All the URLs or links are extracted from web page HTML content using DOMDocument<\/code> class. All links will validate using FILTER_VALIDATE_URL<\/code> before return and print if it is a valid URL.<\/p>\n

$urlContent <\/span>= <\/span>file_get_contents<\/span>(<\/span>'http:\/\/php.net'<\/span>);

<\/span>$dom <\/span>= new <\/span>DOMDocument<\/span>();
@<\/span>$dom<\/span>-><\/span>loadHTML<\/span>(<\/span>$urlContent<\/span>);
<\/span>$xpath <\/span>= new <\/span>DOMXPath<\/span>(<\/span>$dom<\/span>);
<\/span>$hrefs <\/span>= <\/span>$xpath<\/span>-><\/span>evaluate<\/span>(<\/span>\"\/html\/body\/\/a\"<\/span>);

for(<\/span>$i <\/span>= <\/span>0<\/span>; <\/span>$i <\/span>< <\/span>$hrefs<\/span>-><\/span>length<\/span>; <\/span>$i<\/span>++){
    <\/span>$href <\/span>= <\/span>$hrefs<\/span>-><\/span>item<\/span>(<\/span>$i<\/span>);
    <\/span>$url <\/span>= <\/span>$href<\/span>-><\/span>getAttribute<\/span>(<\/span>'href'<\/span>);
    <\/span>$url <\/span>= <\/span>filter_var<\/span>(<\/span>$url<\/span>, <\/span>FILTER_SANITIZE_URL<\/span>);
    <\/span>\/\/ validate url
    <\/span>if(!<\/span>filter_var<\/span>(<\/span>$url<\/span>, <\/span>FILTER_VALIDATE_URL<\/span>) === <\/span>false<\/span>){
        echo <\/span>'<a href=\"'<\/span>.<\/span>$url<\/span>.<\/span>'\">'<\/span>.<\/span>$url<\/span>.<\/span>'<\/a><br \/>'<\/span>;
