how to split an alphanumeric string into an array - php

I am having an alphanumeric string
t14u1e7f8h15j4m3n50o65r22q29
I would like to transform this string into an array,in order to save space I have purposely made it that way.,Now the issue i'm facing right now is that in order to tranform it into an array using php , the order be like
data: [14, 1, 7, 8, ..]
categories : [t,u,e,f,h,j,m,n,o]
also is it possible to further transform categories into:
categories : [20:00,21:00,5:00,f,h,j,m,n,o]
where a => 1:00
b => 2:00
also since the order is like t,u,e,f,h,j is it possible to arrange them alphabetically maximum of 10 characters i.e
categories [a,b,c,d,e,f,g,i,j,k] that is 10 hours from current time..

This should work for you:
(I assume that you only use lowercase letters)
<?php
$string = "t14u1e7f8h15j4m3n50o65r22q29";
$result = array("data" => array(), "categories" => array(), "categories" => array());
preg_match_all("/\d+/", $string, $matches);
$result["data"] = $matches[0];
preg_match_all("/[^\d+]/", $string, $matches);
$result["categories"] = $matches[0];
foreach($result["categories"] as $v) {
$result["categories2"][] = ord(strtolower($v))-96;
}
print_r($result);
?>
Output:
Array
(
[data] => Array
(
[0] => 14
[1] => 1
[2] => 7
[3] => 8
[4] => 15
[5] => 4
[6] => 3
[7] => 50
[8] => 65
[9] => 22
[10] => 29
)
[categories] => Array
(
[0] => t
[1] => u
[2] => e
[3] => f
[4] => h
[5] => j
[6] => m
[7] => n
[8] => o
[9] => r
[10] => q
)
[categories2] => Array
(
[0] => 20
[1] => 21
[2] => 5
[3] => 6
[4] => 8
[5] => 10
[6] => 13
[7] => 14
[8] => 15
[9] => 18
[10] => 17
)
)

convert the array to the correct form

After converting the file
$rows = array_map('trim', file($lines1));
foreach ($rows as $key => $value) {
$params = array_map('trim', explode(';', $value));
}
an array of the following type is obtained, which is contained in a variable:
Array ( [0] => 0 [1] => 1 [2] => 2 [3] => i need this [4] => 4 [5] => 5 [6] => 6 [7] => 7 [8] => 8 [9] => 9 [10] => 10 [11] => 11 [12] => 12 [13] => 13 [14] => 14 )
Array ( [0] => 0 [1] => 1 [2] => 2 [3] => i need this [4] => 4 [5] => 5 [6] => 6 [7] => 7 [8] => 8 [9] => 9 [10] => 10 [11] => 11 [12] => 12 [13] => 13 [14] => 14 )
etc...
how can you combine these arrays and put the values with the key = 3 into separate variables.
View:
Array ( [0] => i need this [1] => i need this and etc...
$range = range(1, 100);
$result = array_combine($range, $range);

How to get values in an array with many arrays in php?

I am confused with this list of array. I have a text file that contains the values that I will need to insert to the database. I have exploded it so that I can get those separated values.
REP 1020001,3,140822,140822;0111,260.00,23,34,3,54,1,2,4,5,12,23,46;0214,22.00,32,4,11,25,4,12,23,5,2,2,44;0313,25.00,5,52,12,45,12,5,6,7,12,3,33;
My code is just like this:
$read = FileRead($tmp);
$perline = explode(";",$read);
for($j=0; $j<count($perline); $j++)
{
$percomma = explode(",", $perline[$j]);
print_r ($percomma);
}
And the result is this:
Array ( [0] => 1020001 [1] => 3 [2] => 140822 [3] => 140822 ) Array ( [0] => 0111 [1] => 260.00 [2] => 23 [3] => 34 [4] => 3 [5] => 54 [6] => 1 [7] => 2 [8] => 4 [9] => 5 [10] => 12 [11] => 23 [12] => 46 ) Array ( [0] => 0214 [1] => 22.00 [2] => 32 [3] => 4 [4] => 11 [5] => 25 [6] => 4 [7] => 12 [8] => 23 [9] => 5 [10] => 2 [11] => 2 [12] => 44 ) Array ( [0] => 0313 [1] => 25.00 [2] => 5 [3] => 52 [4] => 12 [5] => 45 [6] => 12 [7] => 5 [8] => 6 [9] => 7 [10] => 12 [11] => 3 [12] => 33 ) Array ( [0] => )
What should I do to get the value from the 2nd array to the 4th array? Should I put it inside another array to make it multidimensional? Or there are other ways to solve this?
EDIT
My question is how will I be able to get the values from the print_r($percomma) when there are a lot of arrays in the result. The result array is up there that says And the result is this
EDIT 2
As making the array to be multidimensional I get this as a result:
Array ( [0] => Array ( [0] => 0111 [1] => 260.00 [2] => 23 [3] => 34 [4] => 3 [5] => 54 [6] => 1 [7] => 2 [8] => 4 [9] => 5 [10] => 12 [11] => 23 [12] => 46 ) ) Array ( [0] => Array ( [0] => 0214 [1] => 22.00 [2] => 32 [3] => 4 [4] => 11 [5] => 25 [6] => 4 [7] => 12 [8] => 23 [9] => 5 [10] => 2 [11] => 2 [12] => 44 ) ) Array ( [0] => Array ( [0] => 0313 [1] => 25.00 [2] => 5 [3] => 52 [4] => 12 [5] => 45 [6] => 12 [7] => 5 [8] => 6 [9] => 7 [10] => 12 [11] => 3 [12] => 33 ) ) Array ( [0] => Array ( [0] => ) )
It shows that they're all individual arrays. My code is this:
$read = FileRead($tmp);
$perline = explode(";",$read);
for($j=0; $j<count($perline); $j++)
{
$percomma = explode(",", $perline[$j]);
$entries = array($percomma);
print_r ($entries);
}

The last set of array is what I needed but how can I get those values?
EDIT 4
With my simple mistake I put the array_slice inside my for loop that's why I get too many arrays. Now this is the result of #subas_poudel's answer.

)
you can use multidimensional array to hold all the value. then you can get all the array you want by either $percomma[index you want] or using array_slice.
$read = FileRead($tmp);
$perline = explode(";",$read);
for($j=0; $j<count($perline); $j++)
{
$percomma[] = explode(",", $perline[$j]);
}
echo '<pre>'.print_r (array_slice($percomma,1,3),true).'</pre>';
$array = array
(
array("bla",22,18),
array("blaa",15,13),
array("blaaa",5,2),
array("blaaaa",17,15)
);
for ($row = 0; $row < 4; $row++) {
echo "<p><b>Row number $row</b></p>";
echo "<ul>";
for ($col = 0; $col < 3; $col++) {
echo "<li>".$array[$row][$col]."</li>";
}
echo "</ul>";
}
I'm going to copy/edit your original code posting, to show what I was talking about in my comment.
$read = FileRead($tmp);
$perline = explode(";",$read);
$percomma = array(); //new array-declaration line
for($j=0; $j<count($perline); $j++)
{ $percomma[j] = explode(",", $perline[$j]);
print_r ($percomma[j]);
}
Your first "And the result is" line is a printed sequence of arrays, and would be unchanged by implementing the above tweaks to your code. However, because the values in the $percomma variable are no longer overwritten in each loop that obtains an array from the explode() function, you may now, at any point after the above code, do something like:
print_r($percomma[1]); //re-print 2nd array, or
$ary_el = $percomma[2][1]; //get 2nd element of 3rd array (22.00) into a variable.

Separate each alphabet by using preg_match PHP

i know that this is a beginner level question, but i am stuck here and i need help.
i want to store each alphabet in an array. (Only Alphabets not integers)
let me show you the previous code that i am using
$str = "ab c45 d123ef";
preg_match_all('/./us', $str, $ar);
echo '<pre>';
print_r($ar);
its output
Array
(
[0] => Array
(
[0] => a
[1] => b
[2] =>
[3] => c
[4] => 4
[5] => 5
[6] =>
[7] => d
[8] => 1
[9] => 2
[10] => 3
[11] => e
[12] => f
)
)
But it also separate integers... what i have to change in the preg_match expression, i want this output.
Array
(
[0] => Array
(
[0] => a
[1] => b
[2] =>
[3] => c
[4] => 45
[5] =>
[6] => d
[7] => 123
[8] => e
[9] => f
)
)
preg_match_all('/[\d.]+|./us', $str, $ar);
[\d.] matches a digit or decimal point, the + quantifier after it matches a sequence of them.
Result:
Array
(
[0] => Array
(
[0] => a
[1] => b
[2] =>
[3] => c
[4] => 45
[5] =>
[6] => d
[7] => 123
[8] => e
[9] => f
)
)
A way with preg_split:
$result = preg_split('/(?=\pL)|(?<=\pL)/', $str, -1, PREG_SPLIT_NO_EMPTY);
You obtain:
Array
(
[0] => a
[1] => b
[2] =>
[3] => c
[4] => 45
[5] => d
[6] => 123
[7] => e
[8] => f
)
The current pattern matches two kind of positions, positions followed by a letter (?=\pL), and positions preceded by a letter (?<=\pL).

Get sum of multi-dimensional array in PHP

I need to get the sum of all numeric values in my array for each designated month. Ideally, it would return the following format.
April
total = 22
March
total = 'sum'
Array
(
[April] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] =>
[4] => 3
[5] =>
[6] => 2
[7] => 6
[8] => 3
[9] => 2
)
[March] => Array
(
[0] => 3.19198
[1] => 2.52219
[2] => 3.40053
[3] => 2.42639
[4] => 3.92301
[5] => 3.23758
[6] => 3.22457
[7] => 2.62855
)
Apply array_sum() on each of the sub-arrays using array_map():
$result = array_map('array_sum', $data);
Output:
Array
(
[April] => 22
[March] => 24.5548
)

Set array keys to value of another arrays values - PHP

I have the following:
( [0] => 3 [1] => 2 [2] => 12 [3] => 6 [4] => 8 [5] => 7 [6] => 9 [7] => 10 [8] => 5 [9] => 4 )
I want to use the value of each of those as the key in:
( [0] => 7 [1] => 2 [2] => 10 [3] => 3 [4] => 5 [5] => 6 [6] => 11 [7] => 9 [8] => 4 [9] => 8 )
I've tried this:
foreach ($iOrder as $i)
{
$pOrder[$i] = $pOrder[$p];
$p++;
}
I get this:
( [12] => 2 [10] => 6 [5] => 5 [4] => 7 )
Any thoughts?
Do you mean
$result = array_combine($keys, $values);
?
array_combine()
Frist array, $arr1,
( [0] => 3 [1] => 2 [2] => 12 [3] => 6 [4] => 8 [5] => 7 [6] => 9 [7] => 10 [8] => 5 [9] => 4 )
Second array, $arr2,
( [0] => 7 [1] => 2 [2] => 10 [3] => 3 [4] => 5 [5] => 6 [6] => 11 [7] => 9 [8] => 4 [9] => 8 )
If I understood correct, you want to use the values of $arr1 as keys in $arr2.
$values = array_values($arr1);
=> This gives you the values of $arr1.
you can use, array_combine($keys, $values);
so the resulting array would be,
$result_arr = array_combine(array_values($arr1), array_values($arr2));
However, it may not work as expected if the no of items in two arrays are different.
