PHP Separate comma array into variable / values - php

Question

I have a string in a table field that looks like this:
part1=1,part2=S,part3=Y,part4=200000
To call it from the table I do this:
while($row = mysqli_fetch_array($result)) {
$row['mystring'];
}
My problem is that I need to separate the parts into variables for example:
From this:
part1=1,part2=S,part3=Y,someothername=200000
To This:
$part1 = '1';
$part2 = 'S';
$part3 = 'Y';
$someothername = '200000';
How can I do this?

Answer 1

Use like this
parse_str( str_replace(",", "&", "part1=1,part2=S,part3=Y,someothername=200000") );
Use with there name like:
$part1 // return 1
$part2 // return S
$part3 // return Y
works like you want, see the demo

Answer 2

First split string:
$s = "part1=1,part2=S,part3=Y,part4=200000";
$a = explode(",",$s);
then foreach part of string ("part1=1"...) create an array and explode as variable:
foreach($a as $k=>$v)
{
$tmp = explode("=",$v);
$tmp = array($tmp[0]=>$tmp[1]);
extract($tmp);
}
echo $part1;

Answer 3

If you use PHP 5.3+ you can use array_map
<?php
$string = 'part1=1,part2=S,part3=Y,part4=200000';
array_map(function($a){
$tmp = explode('=', $a, 2);
global ${$tmp[0]}; //make vars available outside of this function scope
${$tmp[0]} = $tmp[1];
}, explode(',', $string));
//Variables available outside of array_map scope
echo $part1 . '<br>';
echo $part2 . '<br>';
echo $part3 . '<br>';
echo $part4 . '<br>';
?>

Answer 4

Double explode your string to get the wanted field :
$string ="part1=1,part2=S,part3=Y,someothername=200000";
foreach (explode(',', $string) as $parts) {
$part = explode('=', $parts);
$array[$part[0]] = $part[1];
}
var_dump($array);
Output :
array(4) {
["part1"]=>
string(1) "1"
["part2"]=>
string(1) "S"
["part3"]=>
string(1) "Y"
["someothername"]=>
string(6) "200000"
}
I wouldn't suggest the use of variable variables to get the output as :
$part1 = ...
$part2 = ...
Using an array is probably the easier and safest way to do here. As suggested in my comment, it avoid potential conflicts with variable names.

Answer 5

You can use something called 'Variable variables'. You can declare the content of a variable as a variable, if you use double dollar sign, instead of a single one. For example:
$fruit = "apple";
$$fruit = "this is the apple variable";
echo $apple;
It would output the following:
this is the apple variable
You have to be a bit more tricky with defining variables from an array, as you'd have to enclode the original variable in curly brackets. (for example: ${$fruit[0]})
So the answer to your question is:
$parts = "part1=1,part2=S,part3=Y,someothername=200000";
$parts_array = explode(",", $parts);
foreach ($parts_array as $value) {
$temp = explode("=", $value);
${$temp[0]} = $temp[1];
}
echo "$part1, $part2, $part3, $someothername";
