Question

I am attempting to create an implode that given the following array:

<?php

    $conditions = array(
         'username' => array('=', 'nblackburn'),
         'password' => array('=', 'password')
    );

    $output = array();
    foreach($conditions as $key => $values) {
        $output[] = $key.' '.implode(' ', $values);
    }

    echo implode(' AND ', $output);

?>

Should return a string like the following:

username = nblackburn AND password = password

However, I am having problems getting it to work. As you can see the first section (username) is the array’s key, the second (=) is the first element in the sub-array and the final (nblackburn) is its last element.

Answer 1

Like this?

$str = array();
foreach($test as $key => $values) {

  // if there are always only 2 values inside
  $str[] = $key .' '.$values[0].' '.$values[1];

  // with more values (taken from nblackburns solution)
  $str[] = $key.' '.implode(' ', $values);
}

echo implode(' AND', $str);

But as mentioned in the comments, don’t use it, if it brings vulnerabilities with it!
