[SOLVED] In str array

[webkill]

Hey guys, check out this function. I have to filter out the array entries that have a certain word somewhere within the string. I've had ago myself using array_filter and in_array but i just cant do it. Can anyone help? Thanks

 

function stt_getinfo() {

 

global $post;

        $post_ID = $post->ID;

$arr = array_unique(get_post_meta($post_ID, 'searchTerm'));

$array2 = array_unique($arr);

if(empty($array2)) {

return false;

} else {

return $array2;

}

}

Yikes thats Wordpress isn't it?

 

I don't quite understand what you are trying to do.  Can you explain in a little more detail?

Basically need to filter $array2. You could ignore rest of code i suppose. I have to filter out the array entries that have a certain word somewhere within the string.

Try this:

 

<?php
function filter_array ($array, $certain_word) {
    $keep = array();
    foreach ($array as $string) {
        if (strpos($string, $certain_word) === false) {
            $keep[] = $string;
        }
    }
    return $keep;
}
?>
