Message:

I want to loop through an multidimensional array, which has multiple keys and arrays of strings assigned to the keys. For each string in the arrays, I want to execute the strip_tags function and replace the old string with the new one.

I am very new to php and I am very confused.

So thanks for your help!

EDIT:

This is what I did so far:

<?php

include ('../db.php');





$sql = "select id, post_title, post_content, post_type, post_date from wp_posts where post_type = 'post' order by post_date desc limit 20";

$ergebnis = $db->query($sql);



$zeile = $ergebnis->fetchALL(PDO::FETCH_ASSOC);



$keys = array_keys($zeile);



$valuearray = array();





for($i=0; $i < count($keys); $i++) {



    foreach($zeile[$keys[$i]] as $key => $value) {

    if(is_string($value) == true) {

        $value1 = strip_tags($value);

        array_push($valuearray, $value1);

        $zeile[$keys[$i]] = $valuearray;

     }

    else {

        array_push($valuearray, $value);

        $zeile[$keys[$i]] = $valuearray;        

        }

 }

}

    





$json = json_encode($zeile);



echo $json;



?>

I need the output as json for flutter development.

My Answer:
Here is an example of how you can loop through a multidimensional array and remove HTML tags from the strings:

php

// Sample multidimensional array
$data = array(
'key1' => array('string1', '

string2

'),
'key2' => array('

string3

', 'string4')
);

// Loop through the array
foreach ($data as $key => $value) {
foreach ($value as $index => $string) {
// Remove HTML tags from the string
$data[$key][$index] = strip_tags($string);
}
}

// Output the updated array
print_r($data);

?>


In this example, we have a multidimensional array `$data` with keys and arrays of strings assigned to the keys. We use nested foreach loops to iterate through each string in the arrays and apply the `strip_tags` function to remove HTML tags. The updated strings are then stored back in the original array.

You can run this code in a PHP file or online PHP editor to see the updated array without HTML tags. Let me know if you need any further clarification or assistance.
