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.
