How to make a string into an array in php

Question

I'm having a string like this..

food_item => 'Butter Croissant',food_id => '1',quantity => '1',price => '140'

I tried explode option

But I'm getting an array like this

Array
(
 [0] => 'food_item' => 'Butter Croissant'
 [1] => 'food_id' => '1'
 [2] => 'quantity' => '1'
 [3] => 'price' => '140'
)

But I should need to make it as an array like as follows,

Array
(
 [food_item] => 'Butter Croissant'
 [food_id] => '1'
 [quantity] => '1'
 [price] => '140'
)

how should I do this,Someone please help me..

Thank you in advance..

• Andy Holmes: Your first "string" is an array, not a string
• Ivan: Maybe he has it as a string...
• Andy Holmes: Maybe, but it is a little confusing
• Aswathy S: If you explode the string using ',' the part of string "food_item => 'Butter Croissant' " will considered as a string
• Salman Arshad: What if food name contains a ,?

Answer 1

Try:

$str = "food_item => 'Butter Croissant',food_id => '1',quantity => '1',price => '140'";
$mainArray = explode(",",$str);
$newArray = array();
foreach($mainArray as $main) {
 $innerArray = explode("=>",$main);
 $newArray[trim($innerArray[0])] = trim($innerArray[1]);
}

Output:

Array
(
 [food_item] => 'Butter Croissant'
 [food_id] => '1'
 [quantity] => '1'
 [price] => '140'
)

You can do it like below:-

<?php
$string = "food_item => 'Butter Croissant',food_id => '1',quantity => '1',price => '140'"; // original string
$first_array = explode(',',$string); // your first explode with `,`
$final_array = array(); // create a new empty array
foreach($first_array as $arr){ // iterate over previously exploded array
 $data = explode('=>',$arr); // now explode the value again with `=>`
 $final_array[trim($data[0])] = trim($data[1]); // add it to final array in the form of key=>value pair
}
echo "<pre/>";print_r($final_array);

Note:- this is easiest stuff to do and to understand also.thanks

• Death-is-the-real-truth: @SuganyaRajasekar glad to help you
• Suganya Rajasekar: @ Anant Yes I did it :)
• Ron van der Heijden: Care with comma's in your string. I would advice a regex. You have a problem with $string = "food_item => 'Butter, Croissant'...

Answer 3

You can use this:

$str = "food_item => 'Butter Croissant',food_id => '1',quantity => '1',price => '140'";
$exploded = array_map('myExplode', explode(',', $str));
$result = [];
foreach ($exploded as $itemPieces) {
 $result[trim($itemPieces[0])] = trim($itemPieces[1]);
}
function myExplode($item) {
 return explode("=>", str_replace("'", '', $item));
}
var_dump($result);

OUTPUT

array (size=4)
 'food_item' => string 'Butter Croissant' (length=16)
 'food_id' => string '1' (length=1)
 'quantity' => string '1' (length=1)
 'price' => string '140' (length=3)

Answer 4

You could use preg_split in combination with foreach Loop for that like so:

 <?php
 $strArray = "food_item => 'Butter Croissant',food_id => '1',quantity => '1',price => '140'";
 $arrKVPairs = preg_split("#,\s?#", $strArray);
 $arrStrToArray = array();
 foreach($arrKVPairs as $ikey=>$strData){
 $arrKeyVal = preg_split("#\s?\=>\s?#", trim($strData, "'"));
 if(count($arrKeyVal) == 2){
 list($key, $val) = $arrKeyVal;
 $arrStrToArray[$key] = trim($val, "'");
 }
 }
 var_dump($arrStrToArray);
 // PRODUCES::
 array (size=4)
 'food_item' => string 'Butter Croissant' (length=16)
 'food_id' => string '1' (length=1)
 'quantity' => string '1' (length=1)
 'price' => string '140' (length=3)

Answer 5

Since we got answers I wanted to post different solution (given string is much like parameters string that can be parsed in array or in vars by parse_str function):

$string = "food_item => 'Butter Croissant',food_id => '1',quantity => '1',price => '140'";
$paramString = str_replace([',', " => ", "'"], ['&', '=', ''], $string);
parse_str($paramString, $data);

Now we got data as needed, and code looks a bit cleaner
