Replace array value with url

I am trying to assign a url to array values once they are printed to the page, but it isn't working with the code that I have. I am attaching the code snippet that I am using to assign the array value and then also the dump of the array. I am just getting "Array" as the print out.

When I do "print_r($field_academic_unit_value); " it does print out the correct value.

Thanks for any help!

$field_academic_unit_value = array();
  if (in_array('New College of Interdisciplinary Arts and Sciences',$field_academic_unit_value))
  {
   $field_academic_unit_value = "http://example.com";
  }
 
//// this is what that array looks like when I do print_r
 
[field_academic_unit] => Array
        (
            [0] => Array
                (
                    [value] => New College of Interdisciplinary Arts and Sciences
                )
 
        )

Thanks for the info - makes sense and really helped!

change line 2:
if (in_array('New College of Interdisciplinary Arts and Sciences',$field_academic_unit_value))

to:
if( in_array( array("value"=>"New College of Interdisciplinary Arts and Sciences") , $field_academic_unit) )

You know, for all the times I've ever used in_array(), I don't think I've ever thought about doing that for a simple multi-dimensional array like his. That's actually much better than my suggestion, hielo.

I will try that one as well! Thanks for the help everyone. Arrays are definitely an area I am weak in,

Well, at least you picked the right language to learn arrays. PHP has fantastic array-handling capabilities and makes it pretty easy to work with them. Once you get a handle on arrays, you'll never figure out how you lived without them.

@gr8gonzo: Excellent explanation.
@SashaIsaac: You got some sick code there!

Consider this:

$field_academic_unit_value = array();
if (in_array('New College of Interdisciplinary Arts and Sciences',$field_academic_unit_value))
{
$field_academic_unit_value = "http://example.com";
}

First you set that $field_academic_unit_value to be an empty array, then you set it to be a character string. Those sort of practices are sure to lead to confusion.

Learn about var_dump() to print out data structures. If you echo "<pre>"; before var_dump() the output is much easier to read.

If you want to describe what you're trying to accomplish in plain language, we maybe able to help you with the code. I am just guessing, but I think you are trying to associate a list of college names with the URLs of the colleges? Maybe this example will be helpful (untested but valid in principle)

<?php
// THE TEST DATA
$schools = array
           (
              "Arts and Sciences" => "www.art.org",
              "Business"          => "www.biz.org",
              "Education"         => "www.edu.org",
           );
           
// ITERATE OVER THE ARRAY TO SHOW THE DATA
foreach ($schools as $college => $url)
{
    echo "<br/>THE COLLEGE OF $college HAS A WEB SITE AT $url \n";
}
