PHP获取Meta标签，Arrays中的URL =不工作[关闭]

Question

I am trying to get the meta tags of the urls entered in the text area, what is wrong with this?

Also, how would I put the URL that the meta description came from with the description?

<form method="get">
<textarea name="TAData">
</textarea>
<input type="submit" value="submit"/>
</form>

<div id="checkboxes">
<input type="checkbox" name="vehicle" value="PR" /> Show me the PR<br />
<input type="checkbox" name="vehicle" value="KW Tag" /> Show me the KW tag<br />
<input type="checkbox" name="vehicle" value="Title Tag" /> Show me the Title tag<br />
</div>
<div id="checkboxes">
<input type="checkbox" name="vehicle" value="1stH1" /> Show me the 1st H1<br />
<input type="checkbox" name="vehicle" value="2ndH1" /> Show me the 2nd H1 tag<br />
<input type="checkbox" name="vehicle" value="SeedKW" /> Show me Seed KW's<br />
</div>

<div id="nofloat"></div>

<?php

//make the array 
$TAarray = explode("
", strip_tags($_POST['TAData'])); 

var_dump($TAarray);

//loop through the array 
foreach ($TAarray as $line) { 


   $line = htmlspecialchars(trim($line)); 
}      

    foreach ($TAarray as $url) {

            // get the meta data for each url
            $tags = get_meta_tags($url);

unset($tags["content-type"]);
unset($tags["page-type"]);
unset($tags["page-topic"]);
unset($tags["audience"]);

                echo '<tr>';
                foreach ($tags['description'] as $meta)         
            {
                        echo '<td>' . $meta . '</td>';
                }
                echo '</tr>';
        }
?>

Also, is there a way to only include the meta description?

Answer 1

1) your form is declared as GET, but you are reading values from $_POST field.

2) if you want to extract just the "description" meta value, you don't need to do the iteration over tags, you can just use:

$description = $tags["description"]
