Veering off ever so slightly to one side -- I've never done the &$var thing in order to insert data into an extant array like this - instead I've simply generated a new array, often bringing one of the values from the array (say the id field from the table) into play as the key for a new dimension. Err, you know what I mean.
Anyhoo, out of curiosity I had a quick play with the reference approach, as described on that PHP.net page I cited earlier, and I'm seeing an odd appearance of an ampersand in my output.
Here's my code:
Code:
<?php
$foo = array();
$foo[] = array ("a"=>"alpha", 'b'=>"bravo", 'c'=>"charlie");
$foo[] = array ("a"=>"alpha", 'b'=>"bravo", 'c'=>"charlie");
var_dump ($foo);
echo " --- ";
foreach ($foo as &$bar)
$bar['d'] = 'delta';
var_dump ($foo);
This is the unadulterated output that's generated - specifically note the
1 = & bit in the second section.
Code:
array
0 =>
array
'a' => string 'alpha' (length=5)
'b' => string 'bravo' (length=5)
'c' => string 'charlie' (length=7)
1 =>
array
'a' => string 'alpha' (length=5)
'b' => string 'bravo' (length=5)
'c' => string 'charlie' (length=7)
---
array
0 =>
array
'a' => string 'alpha' (length=5)
'b' => string 'bravo' (length=5)
'c' => string 'charlie' (length=7)
'd' => string 'delta' (length=5)
1 => &
array
'a' => string 'alpha' (length=5)
'b' => string 'bravo' (length=5)
'c' => string 'charlie' (length=7)
'd' => string 'delta' (length=5)
If I add in an extra array in the setup - the & appears on 2 => &, but not on 1 - ie, it follows the
last array's index.
Any ideas?
