I have a number of strings, that contain the bracket literals:
0 => string '[139432,97]' (length=18)
1 => string '[139440,99]' (length=18)
I need to create string arrays of [139432,97] and [139440,99].
I've tried using json_decode(), but while it works, it creates arrays as float or int using the above data, however I want them as strings.
array (size=2)
0 => float 139432
1 => int 97
array (size=2)
0 => float 139440
1 => int 97
You can put double quotes around the values e.g.
0 => string '["139432","97"]' (length=22)
1 => string '["139440","99"]' (length=22)
This way when you json_decode they should be strings.
Edit:
OK I thought you could control the input - if not then a simple trim and explode could do:
explode(',', trim('[139432,97]', '[]'));
array(2) {
[0]=>
string(6) "139432"
[1]=>
string(2) "97"
}
Is that enough?
Just combining what you already now (json_decode) and what #AlixAxel suggested here you can extract those values to string link:
$subject = '[139432,97]';
$convertedToArrayOfStrings = array_map('strval', json_decode($subject));
or
$convertedToArrayOfString = array_map(function($item){return (string) $item;}, json_decode($subject));
for better performance, see the comment bellow please :)
Why not try with loop and use explode function:
$array = array('139432,97', '139440,99');
$finalArray = array();
$i = 0;
foreach ($array as $arr) {
$explode = explode(",", $arr);
$j = 0;
foreach ($explode as $exp) {
$finalArray[$i][$j] = (int)$exp;
$j++;
}
$i++;
}

I got this array:
$array = array('E1211','E2172','E2181','E233','E241','E286');
And I need to order first by first number-letter, i.e. E1, E2, E3, E4... followed by ordered numbers from lowest to highest.
Desired order would be: E1211, E233, E241, E286, E2172, E2181
If i do sort($array); the order will will be: "E1211", "E2172", "E2181", "E233", "E241" "E286".
If i do natsort($array); it will order by numbers from lowest to higest: "E233", "E241", "E286", "E1211", "E2172", "E2181"
Use usort() with a custom comparison function to split the strings and compare the portions.
<?php
$array = array('E1211','E2172','E2181','E233','E241','E286');
usort($array, function($a, $b){
$pfxA = substr($a,0,2); // Get the first two characters of each string
$pfxB = substr($b,0,2);
if ( $pfxA !== $pfxB) {return $pfxA<=>$pfxB;} // If they're not equal, return the spaceship comparison
return (int)substr($a,2)<=>(int)substr($b,2); // Prefixes are equal. Convert the rest to integers and return the spaceship comparison.
});
var_dump($array);
Output:
array(6) {
[0]=>
string(5) "E1211"
[1]=>
string(4) "E233"
[2]=>
string(4) "E241"
[3]=>
string(4) "E286"
[4]=>
string(5) "E2172"
[5]=>
string(5) "E2181"
}

Actually what you want to do is mixing sorting with your own pattern with natsort(). I doubt if it can be accomplished by some oneliner, however it can be done with simple iteration in separate steps, that code does what I think you want (input data modified for better readibility).
<?php
$array = ['E3123', 'E1211', 'E2181', 'E241', 'E286', 'E2172', 'E233'];
$newArray = [];
$finalArray=[];
// Put it into associative array with required keys (two first chars)
foreach ($array as $item) {
$key = substr($item, 0, 2);
$newArray[$key][] = $item;
}
// sort new array by key (two first chars)
ksort($newArray);
// sort each subarray in natural order and put it to final array
foreach ($newArray as $key => $newItem) {
natsort($newArray[$key]);
$finalArray = array_merge($finalArray, $newArray[$key]);
}
// just check
var_dump($finalArray);
Result:
array (size=7)
0 => string 'E1211' (length=5)
1 => string 'E233' (length=4)
2 => string 'E241' (length=4)
3 => string 'E286' (length=4)
4 => string 'E2172' (length=5)
5 => string 'E2181' (length=5)
6 => string 'E3123' (length=5)
I am inserting string with multiple delimiters and split it using explode function to mysql database table but i failed in building proper logic.
I tried with single delimiter i-e , and successfully insert that record.
Now i want to split string with | and ,.
I used for row separation and | for value seperation.
i-e
$var = "Facebook|http://facebook.com/123|12312|12 to 13,Twitter|http://twitter.com/231|12321|12 to 13";
$cat="2,3";
$i=0;
$arrayOfCategories = explode(",", $cat);
foreach ($arrayOfCategories as $categories) {
$datas[$i]['UserID'] = 2;
$datas[$i]['CatID'] = $categories;
$i++;
}
var_dump($datas);
Format showed using var_dump is the format which i want to insert using insert_batch of codeigniter.
This is the expected output
array (size=2)
0 => array (size=2)
'SocialName' => string 'Facebook'
'URL' => string 'facebook.com/123'
1 => array (size=2)
'SocialName' => string 'Twitter'
'URL' => string 'twitter.com/231'
$array = array();
$string = "Facebook|http://facebook.com/123|12312|12 to 13,Twitter|http://twitter.com/231|12321|12 to 13";
$rows = explode(',', $string);
foreach ($rows as $row) {
$values = explode('|', $row);
$array[] = array('SocialName' => $values[0], 'URL' => $values[1]);
}
var_dump($array);
Create an array $array to store the final result in.
Now, split the input string $string on , using explode, this gives you the "rows".
Go through all the rows (foreach), and split each row on the | (explode), this gives you the "values".
The first value $values[0] is the "SocialName", and the second value $values[1] is the "URL", so add those to a new array, and add that new array to the final result array $array.
I have a string:
01;Tommy;32;Coder&&02;Annie;20;Seller
I want it like this:
array (size=2)
0 =>
array (size=4)
0 => string '01' (length=2)
1 => string 'Tommy' (length=5)
2 => int 42
3 => string 'Coder' (length=5)
1 =>
array (size=4)
0 => string '02' (length=2)
1 => string 'Annie' (length=5)
2 => int 20
3 => string 'Seller' (length=6)
Hope you can help me, thank you!
Not sure if the datatypes will be matching (as I believe it's all in a string) but here's the code
$myarray = array();
foreach(explode("&&",$mystring) as $key=>$val)
{
$myarray[] = explode(";",$val);
}
The explode command takes a string and turns it into an array based on a certain 'split key' which is && in your case
but since this is a dual array, I had to pass it through a foreach and another explode to solve.
It's very simple. First you need to explode the string by && and then traverse through array exploded by &&. And explode each element of an array by ;.
Like this,
<?php
$str="01;Tommy;32;Coder&&02;Annie;20;Seller";
$array=explode("&&",$str);
foreach($array as $key=>$val){
$array[$key]=explode(";",$val);
}
print_r($array);
Demo: https://eval.in/629507
you should just have to split on '&&', then split the results by ';' to create your new two dimensional array:
// $string = '01;Tommy;32;Coder&&02;Annie;20;Seller';
// declare output
$output = [];
// create array of item strings
$itemarray = explode('&&',$string);
// loop through item strings
foreach($itemarray as $itemstring) {
// create array of item values
$subarray = explode(';',$itemstring);
// cast age to int
$subarray[2] = (int) $subarray[2]; // only useful for validation
// push subarray onto output array
$output[] = $subarray;
}
// $output = [['01','Tommy',32,'Coder'],['02','Annie',20,'Seller']];
keep in mind that since php variables are not typed, casting of strings to ints or keeping ints as strings will only last depending on how the values are used, however variable type casting can help validate data and keep the wrong kind of values out of your objects.
good luck!
There is another appropach of solving this problem. Here I used array_map() with anonymous function:
$string = '01;Tommy;32;Coder&&02;Annie;20;Seller';
$result = array_map(function($value){return explode(';',$value);}, explode('&&', $string));
Our Story: (short version below if you're eager to troubleshoot)
This question is asked after extensively searching for a way to get a multidimensional array (with named keys) back into it's CSV file. You might say: "But this is covered on multiple pages on SO, search better!" but we did, and the results we found we have tried to bend to our will, but failed.
The reason for this in the first place was to remove columns from the CSV that were interfering with the rest of our Query's and Code.
So now we're back to ask on SO:
We've read the CSV into a multidimensional Array, using the headers' 1st line as key names.
We then used unset($array[$i]['insert_date']); to remove the columns from the array
We also str_replace'd those columns names from our $header variable.
So we're extensively reading out csv's, putting them in awesome Arrays that have a numerical first index, and second dimension keys named after the first line of our CSV file.
We also have the original Header from CSV file stored in a variable handsomely called $header with a string like: '"brand";"category";"category_path"
So.. $header is a string, $array is our multidimensional array.
All we want to do, and we're stuck editing loop after loop, is to create a brand new File, that has our $header as the first line, and our $array's values as strings..
file to write to: $putfile = fopen("feeds/broken/lu-zz.csv", "rw");
we're using: fputcsv($file, $array,';','"'); to write
and preferably: \n line endings
In short:
from this:
array (size=3886)
0 =>
array (size=19)
'brand' => string 'Tommy Hilfiger' (length=14)
'category' => string '' (length=0)
'category_path' => string 'Heren|Jeans|Blue jeans' (length=22)
1 =>
array (size=19)
'brand' => string 'Marc Aurel' (length=10)
'category' => string '' (length=0)
'category_path' => string 'Dames|Jurken|Zomerjurken' (length=24)
2 =>
array (size=19)
'brand' => string 'Rinascimento' (length=12)
'category' => string '' (length=0)
'category_path' => string 'Dames|Jurken|Print jurken' (length=25)
To This
"brand";"category";"category_path"
"Tommy Hilfiger";"";"Heren|Jeans|Blue jeans" (/n)
"Marc Aurel";"";"Dames|Jurken|Zomerjurken" (/n)
"Rinascimento";"";"Dames|Jurken|Print jurken" (/n)
Last piece of code we tried:
{
foreach($subarray as $value){
for ($i=0, $m=count($value); $i<$m; $i++){
//$test = implode('";"',$subarray) ;
//$tmp = array();
$result = call_user_func_array('array_merge', $subarray);
//$tmp[]= array_merge($subsub[$i]);
var_dump($result);
fputcsv($putfile, $subarray,';','"');
}
}
} fclose($putfile);
This just returns the same value over and over again into an array:
foreach ($array as $subarray) {
foreach($subarray as $value){
for ($i=0, $m=count($value); $i<$m; $i++){
//$test = implode('";"',$subarray) ;
//$tmp = array();
print_r($subarray);
fputcsv($putfile, $subarray,';','"');
}
}
} fclose($putfile);
Solution in our case: Thanks to "Don't Panic" & "CBroe".
$putfile = fopen("feeds/stukkefeeds/lu-zz.csv", "wb");
$header = str_replace('"','',$header1);
$titel = explode(';',$header);
var_dump($titel);
// then write in your data
fputcsv($putfile, $titel,';','"');
foreach ($array as $line) {
fputcsv($putfile, $line,';','"');
}
It looks like you may be making it more complicated than it needs to be. If you have an $array that is the one you've shown that looks like:
array (size=3886)
0 =>
array (size=19)
'brand' => string 'Tommy Hilfiger' (length=14)
'category' => string '' (length=0)
'category_path' => string 'Heren|Jeans|Blue jeans' (length=22)
...
And you have a working file handle that you've opened with
$putfile = fopen("feeds/broken/lu-zz.csv", "w");
You shouldn't need a nested loop at all. You can get the header line by using array_keys on the first item in the array (or any item, really), write it to the file with fputcsv, and then loop over the array and write each line of data, also with fputcsv.
$first_line = reset($array); // get the first line
fputcsv($putfile, array_keys($first_line)); // use its keys to write the headers
// then write in your data
foreach ($array as $line) {
fputcsv($putfile, $line,';','"');
}
Looks like you are thinking way too complicated here ...
$firstIteration = true;
foreach($yourArray as $elem) {
if($firstIteration ) { // if this is the first array element,
// write out its keys to create the CSV heading line
echo implode(';', array_keys($elem)) .'<br>';
$firstIteration = false;
}
echo implode(';', $elem) .'<br>'; // output the data for each array element
}
(Notice that I used echo and implode here for demonstration purposes; the result will not have the enclosing " - switching that out for writing CSV to the file again should be no issue.)
In PHP I have an array like this:
array
0 => string 'open' (length=4)
1 => string 'http://www.google.com' (length=21)
2 => string 'blank' (length=5)
but it could also be like:
array
0 => string 'blank' (length=5)
1 => string 'open' (length=4)
2 => string 'http://www.google.com' (length=21)
now it is easy to find "blank" with in_array("blank", $array) but how can I see if one string is starting with "http"?
I've tried with
array_search('http', $array); // not working
array_search('http://www.google.com', $array); // is working
now everything after `http? could vary (how to write vary, varie? could be different is what I mean!)
Now do I need a regex or how can I check if http exists in array string?
Thanks for advices
"Welcome to PHP, there's a function for that."
Try preg_grep
preg_grep("/^http\b/i",$array);
Regex explained:
/^http\b/i
^\ / ^ `- Case insensitive match
| \/ `--- Boundary character
| `------ Literal match of http
`--------- Start of string
Try using the preg_grep function which returns an array of entries that match the pattern.
$array = array("open", "http://www.google.com", "blank");
$search = preg_grep('/http/', $array);
print_r($search);
Solution without regex:
$input = array('open', 'http://www.google.com', 'blank');
$output = array_filter($input, function($item){
return strpos($item, 'http') === 0;
});
Output:
array (size=1)
1 => string 'http://www.google.com' (length=21)
You can use preg_grep
$match = preg_grep("/http/",$array);
if(!empty($match)) echo "http exist in the array of string.";
or you can use foreach and preg_match
foreach($array as $check) {
if (preg_match("/http/", $check))
echo "http exist in the array of string.";
}
