Create Associative Array inside a for loop - php

Question

Hi I've created an array with a for loop inside. The array doesn't have any data inside it until it reaches the for loop. I wanted to add an associative array to what I've done so far. For example my array currently ouputs
[0] => Array
(
[0] => Version 5
[1] => Feb-16
[2] => gary
[3] => 80
[4] => P
)
I would like it to have headings instead of numbers
[0] => Array
(
Version => Version 5
Date => Feb-16
Name => gary
RandNum => 80
Letter => P
}
I'm not sure how i'd fit into my loop and how I could if my different columns these headings. Below is my current code. Which outputs the array at the top.
for($i = 0; $i <= 3; $i++){
for($j = 0; $j <= 4; $j++){
if ($j == 0){
$times_table[$i][$j]= "Version 5" ;
}
else if ($j == 1){
$cur_date = date("M-y", $currentdate);
$currentdate = strtotime('+1 month', $currentdate);
$times_table[$i][$j]= "<strong>" . $cur_date . "</strong>" ;
}
else{
$times_table[$i][$j]= "gary" ;
}
if ($j == 3) {
$numbers = mt_rand(1, 100);
$times_table[$i][$j]= $numbers ;
}
if ($j == 4){
if($i == 0 || $i == 3)
{
$pay = "P";
$times_table[$i][$j]= $pay ;
}
else{
$int = "I";
$times_table[$i][$j]= $int ;
}
}
}
}

Try this..
for($i = 0; $i <= 3; $i++){
for($j = 0; $j <= 4; $j++){
if ($j == 0){
$times_table[$i]['Version']= "Version 5" ;
}
else if ($j == 1){
$cur_date = date("M-y", $currentdate);
$currentdate = strtotime('+1 month', $currentdate);
$times_table[$i]['Date']= "<strong>" . $cur_date . "</strong>" ;
}
else{
$times_table[$i]['Name']= "gary" ;
}
if ($j == 3) {
$numbers = mt_rand(1, 100);
$times_table[$i]['RandNum']= $numbers ;
}
if ($j == 4){
if($i == 0 || $i == 3)
{
$pay = "P";
$times_table[$i]['Letter']= $pay ;
}
else{
$int = "I";
$times_table[$i]['Letter']= $int ;
}
}
}
}
Hope this will solve your problem.

In my opinion, your second for loop is not needed. You should know that you can create associative arrays like this :
<?php
$times_table = [];
$times_tables[] = [
'Version' => 'Version 5',
'Date' => 'Feb-16',
'Name' => 'gary',
'RandNum' => '80',
'Letter' => 'P',
];
To match with your code :
<?php
$times_table = [];
for($i = 0; $i <= 3; $i++){
$times_table[$i]['Version']= "Version 5" ;
$cur_date = date("M-y", $currentdate);
$currentdate = strtotime('+1 month', $currentdate);
$times_table[$i]['Date']= "<strong>" . $cur_date . "</strong>" ;
$times_table[$i]['Name']= "gary" ;
$numbers = mt_rand(1, 100);
$times_table[$i]['RandNum']= $numbers ;
switch ($i) {
case 0:
case 3:
$letter = 'P';
break;
default:
$letter = 'I';
}
$times_table[$i]['Letter']= $letter;
}
I think this should do what you want in a cleaner way !

for($i = 0; $i <= 3; $i++){
for($j = 0; $j <= 4; $j++){
if ($j == 0){
$times_table["Version"][$j]= "Version 5" ;
}
else if ($j == 1){
$cur_date = date("M-y", $currentdate);
$currentdate = strtotime('+1 month', $currentdate);
$times_table["Date"][$j]= "<strong>" . $cur_date . "</strong>" ;
}
else{
$times_table["Name"][$j]= "gary" ;
}
if ($j == 3) {
$numbers = mt_rand(1, 100);
$times_table["RandNum"][$j]= $numbers ;
}
if ($j == 4){
if($i == 0 || $i == 3)
{
$pay = "P";
$times_table["Letter"][$j]= $pay ;
}
else{
$int = "I";
$times_table["Letter"][$j]= $int ;
}
}
}
}

Answer 4

You can create associative array like this:
$a=array("Version"=> "Version 5",
"Date"=> "Feb-16",
"Name" => "gary",
"RandNum" => 80,
"Letter" => "P"
)
To access this array in for loop use $a['key']. For eg. to access version5, use $a['version'], to access Feb-16 use $a['Date'].
