Can't edit any value in an array

[ryland22]

I have an array:

<?php

$var1 = "mike";
$var2 = 3;
$var3= "red";

$arr= array("uno"=> array($var1,$var2,$var3));
$arr['uno'][]=array("kim",5, "green");

?>

Thus, the array looks like this:

Array ( [uno] => Array ( [0] => jim [1] => 3 [2] => red ) [0] => Array ( [0] => kim [1] => 5 [2] => green ) )

I am unable to edit any of the values in the array, for example if I wanted to change the name "Mike" to "Jim" I tried to do this:

$arr["uno"][0]="jim"

But the value "mike" doesn't change. Any ideas???

[ryland22]

Ok, so I figured out how to modify the array by using the below code:

$arr['cart'][0][0]="jim";

However, I have a new problem. When I loop through the array, after the loop is over I then try to modify the array and my above code modifies "kim" instead of "mike". Any help???

No it doesn't. It looks like this

Array ( [uno] => Array ( [0] => mike [1] => 3 [2] => red [3] => Array ( [0] => kim [1] => 5 [2] => green ) ) )

Try and figure out why this might be.

[tekky]

['uno'][0] => jim
['uno'][1] => 3
['uno'][2] => red
[0][0] => kim
[0][1] => 5
[0][2] => green

maybe that will help you see your problem 😉

Ok, that does help significantly. Question though, what if I did this:

$var1 = "mike"; 
$var2 = 3; 
$var3= "red"; 

$arr= array("uno"=> array($var1,$var2,$var3)); 
$arr['uno'][]=array("kim",5, "green"); 
$arr['uno'][]=array("rick",7,"orange");

Do I have the following?

['uno'][0] => jim
['uno'][1] => 3
['uno'][2] => red
[0][0] => kim
[0][1] => 5
[0][2] => green
[1][0] =>rick
[1][1]=>7
[1][2]=>orange

try using something like...

echo '<pre>'. print_r($arr).'</pre>';

to see how your array looks

If I loop through the array in the code below and I try to modify $arr['uno'][0][0] it works on the second row of the array ("kim"), if I modify $arr['uno'][1][0] it modifies the third row of the array ("tim"). I used the reset function, but to no avail. How do I modify the first row of the array (eg: "mike")??

<?php
$arr['uno']=array("mike", 2, "red");
$arr['uno'][]=array("kim",5, "green");
$arr['uno'][]=array("tim", 7, "orange");

foreach ($arr['uno'] as $arrnew) {
	if ($arrnew[0]=="mike"){
	echo "mike does exist<br>";
	echo $arrnew[1];
	reset($arr['uno']);
	$arr['uno'][0][0]="eatme";
}
}
?>

that should show you where you are wrong...

[ryland22]

I understand how the array looks, using the function

 print_r ($arr['uno']);

reveals the array to me. What I can't figure out is why when I run a loop, I can't seem to edit the first row of the array. Can you help (see code I posted previously for reference)?

[tekky]

thats why im saying use print_r($arr) so you can see the WHOLE array, because you arent assigning the 3 arrays in the same fashion...

from looking at it... you have

$arr['uno'][0]=mike
$arr['uno'][1]=2
$arr['uno'][2]=red
$arr['uno'][0][0]=kim
$arr['uno'][0][1]=5
$arr['uno'][0][2]=green
$arr['uno'][1][0]=tim
$arr['uno'][1][1]=7
$arr['uno'][1][2]=orange

make any sense?
