Here is example which I have try
<?php
include 'spider/classes/simple_html_dom.php';
$html = new simple_html_dom();
$html->load("<html><body><h2>Heading 1</h2><h2>This heading 2</h2></p></p></body></html>");
$e = $html->find("h2", 0);
$key = array();
if($e->plaintext != ""){
foreach($html->find("h2", 0) as $e){
//echo $e->plaintext;
array_push($key, $e->plaintext);
}
} else {
echo "error";
}
print_r($key);
?>
Result:
Array ( [0] => [1] => [2] => [3] => [4] => [5] => Heading 1This heading 2
[6] => [7] => )
How Do i use array_push to create an array?
What happens, when you try this code? I removed the first "find" and i also found an example on the internet, where the second param of "find" was not set.
<?php
include 'spider/classes/simple_html_dom.php';
$html = new simple_html_dom();
$html->load("<html><body><h2>Heading 1</h2><h2>This heading 2</h2></p></p></body></html>");
$key = array();
if(isset($html)){
foreach($html->find("h2") as $e){
//echo $e->plaintext;
array_push($key, $e->plaintext);
}
} else {
echo "error";
}
print_r($key);
?>
Explanation:
// Find all anchors, returns a array of element objects
$ret = $html->find('a');
// Find (N)th anchor, returns element object or null if not found (zero based)
$ret = $html->find('a', 0);
