[SOLVED] Position in array in a foreach loop

[smc]

Hey everyone,

 

I have a script that checks an array for names and if that person's name is there it will e-mail them a particular variable.

 

Here is the setup:

 

an array such as $names = array( $name1, $name2, $name3, $name4 ); etc.

 

Then a foreach loop

 

foreach ( $names as $person ){

 

if ( $key == 1 ){

  $color = blue;

}

 

}

 

However I need something that will get the position in the array of the variable that the foreach loop is dealing with. I tried array_search but that gets screwed up if someone is in the array more than once, it will then only stop at the first time they are in the away.

 

I would appreciate any help you can offer!

If the array values are stored like this:

 

0 => name1

1 => name2

 

Then you can access the 0 or 1 value like this:

 

<?php

foreach($names as $pos => $person) {
...
}

?>

Well this is the current setup of the array:

 

$anchors = array( $m_anchor1, $m_anchor2, $t_anchor1, $t_anchor2, $w_anchor1, $w_anchor2, $th_anchor1, $th_anchor2, $f_anchor1, $f_anchor2, $m_director, $t_director, $w_director, $th_director, $f_director, $m_weather, $f_weather, $t_sports, $f_sports );

 

If I add the 0 => $m_anchor1, 1 => $m_anchor2  will it work? Or will it still work as is?

As far as I know there isn't a way to get the key if they haven't been defined by the user. I'd define the keys yourself

By default, an array has numerical indices, you can see this by doing either

<?php
$anchors = array( $m_anchor1, $m_anchor2, $t_anchor1, $t_anchor2, $w_anchor1, $w_anchor2, $th_anchor1, $th_anchor2, $f_anchor1, $f_anchor2, $m_director, $t_director, $w_director, $th_director, $f_director, $m_weather, $f_weather, $t_sports, $f_sports );
echo '<pre>' . print_r($anchors,true) . '</pre>';
?>

or

<?php
$anchors = array( $m_anchor1, $m_anchor2, $t_anchor1, $t_anchor2, $w_anchor1, $w_anchor2, $th_anchor1, $th_anchor2, $f_anchor1, $f_anchor2, $m_director, $t_director, $w_director, $th_director, $f_director, $m_weather, $f_weather, $t_sports, $f_sports );
foreach ($anchors as $i => $v)
    echo $i . ' := "' . $v  . "<br>';
?>

Thanks chigley, that did it!

 

Also thank you Ken, I've saved that for later use!
