Please help. I want to print the price. I need to print the price only. Help me. Thanks
$x=array(array('itm_name'=>'Optimization','price'=>'100','desc'=>'Chuchu'));
It seems you are using a 2 dimensional array
have you tried
echo $x[0]['price']
note '0' is the first element of the 1st layer of the array
so this can be substituted with 'x' so can iterate through a list
additionally if you want to get the other items of the array then
echo $x[0]['itm_name']
i hope you have grasped the basic concept of multi-dimensional arrays
using this simple explanation
Use this:
$x[0]['price']
$x[0] means the first element of the outer array, and ['price'] gets the price element of the inner array.

When working with existing code, it takes one array and places it into another in the fashion shown below.
I believe the empty brackets are the same thing as simply pushing it and appending it to the first available index.
$g['DATA'][] = $p;
After this is done, I have my own array that I would like to append to this as well. I tried using array_merge() with $g['DATA'][]as a parameter, but this is invalid for obvious reasons.
My only thought is to create a foreach loop counter so I can figure out the actual index it created, however I have to assume there is some cleaner way to do this?
Just simply use the count() of your $g["DATA"] array as index and then you can merge it like this:
$g['DATA'][count($g["DATA"])-1] = array_merge($g['DATA'][count($g["DATA"])-1], $ownArray);
//^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^
// -1 Because an array is based index 0 -> means count() - 1 = last key
I have created multiple arrays from text documents that are uploaded monthly. One of the Arrays item numbers, description and picture. the other array is item numbers, price and quantity.
What I am trying to do is if the item number is the same then be able to Echo out all the information that I need. Example would be
if($array1[0] ==$ array2[4]){
echo $array1{4];
echo $array2[6];
}
this doesn't work and having issues with getting array_intersect to work with it also.
I don't really understand how there are so many variable inside an array. Item's number, description, and picture inside an array? I assuming you are looking for matching item's number inside both arrays so..
Good luck trying:
foreach($array1 as $a){
foreach($array2 as $b){
if($a==$b){
echo $a;
}
}
}
Let me know how it works for you soon.
this didnt work for what I was trying to do but I did figure it out. I needed to use strpos() in a if statement to get the items I was looking for.
I need to figure out how to get the remaining values left in an Array.
Example: I have an array that randomly get two values. I want to get how many are left in that array after removing it.
If i remove 5 values from the array, and have a total of 20 return value 15.
Edit: If i have 52 cards in a deck, I draw 2 cards I have 50. If I draw two more cards i have 48.
I need to track how many "cards" are in the dealers array.
This should work:
$deck = array(1,2,3,4,5,6,7,8,9,10);
unset($deck[0]);
unset($deck[1]);
echo count($deck);
unset removes the elements from the array count should be 8 afterwards.
See it work: https://eval.in/163527
Edit:
...and remember arrays are 0 based so your first key unless otherwise defined will be 0. But the count() function will tell you the actual number of elements in the array. So $deck[count($deck)]; would be undefined.
This will echo size of array yourarray
<?php
echo(sizeof($yourarray));
?>
Store your array size using a count method such as count or sizeof store it in a variable and perform logical checks on it? i.e if().. etc . Your question is a tad bit broad.
I would recommend that you make use of the PHP count function.
echo count($yourArray);
Should do the trick.
I have a dynamically built nested array from which i need to drop one or more indexes.
Having scoured the php information pages, i found that using
unset($quotes_array[0]['methods'][3]);
would remove the last set of data in the array.
But, if i try to use
unset($quotes_array[0]['methods'][0]);
or any other set apart from the last, it messes up the output that is generated from the array.
For instance, if i had a,b,c,d: I can remove d without issue, but if i try to remove a,
i get a blank radio button followed by b,c, with d missing all together when the array data is processed.
I am assuming i need to reindex the array, but every attempt i've made so far has failed to give the required results, most likely because i'm reindexing $quotes_array, whereas the data i actually need to reindex is that within the 'methods' indices.
Is there a way to fix this issue?
unsetting the first element is easy if you use array_shift. array_shift will pop the first element off and reindex your array for you.
array_shift($quotes_array[0]['methods']);
if you need to unset something in the middle (such as [ 2 ] out of [ 3 ]) you could use array_values. First unset the element you want to remove, then reindex them with array_values.
unset($quotes_array[0]['methods'][2]);
array_values($quotes_array[0]['methods']);
if you wanted to remove the last element of an array you could use array_pop. array_pop will pop the last element off the array. There is no need to reindex in this situation.
array_pop($quotes_array[0]['methods']);
try
array_values($quotes_array[0]['methods']);
Can someone explain what is happening in these codes?
I don't understand how cols and rows are being used.
Thank you
$chartdata['cols'][] = array('label'=>'Days Range','type'=>'string');
$chartdata['rows'][] = array('c'=>array(array('v'=>$month),array('v'=>$prevyearbal)));
how these associative arrays get saved in the two dimensional array?
Is $chardata['cols'][] going from row 0 to row n?
As explained in the documentation, assigning to [] is basically the same as array_push but without the function call.
