php - Regular Expression to match someting that starts with - php

I am terribly sorry but the array looks like this:
Array
(
[1] => Array
(
[0] => msie6.0
[1] => 7
)
[2] => Array
(
[0] => safari5.0.3
[1] => 5
)
[3] => Array
(
[0] => chrome18.0.1025.308
[1] => 1
)
[4] => Array
(
[0] => firefox20.0
[1] => 4
)
[5] => Array
(
[0] => msie7.0
[1] => 915
)
and so on...
When i try to replace for example msie6.0and msie7.0 with InternetExplorer and add it occurence :
preg_match("/#^msie(.*)$#i/is", $results, $matches);
$test = $matches[0] ;
print_array($test);
$results["#^startText(.*)$#i"] = $results['InternetExplorer'];
print_array($results);
unset($results["/#^msie(.*)$#i/is]);
it not match the perfect as i want. any solution for that ?
in order to have :
Array
(
[1] => Array
(
[0] => InternetExplorer
[1] => 922
)
[2] => Array
(
[0] => safari5.0.3
[1] => 5
)
[3] => Array
(
[0] => chrome18.0.1025.308
[1] => 1
)
[4] => Array
(
[0] => firefox20.0
[1] => 4
)

After your clarification in comment. I think you don't need regex, strpos is enough too that job.
$rows["InternetExplorer"] = 0;
foreach($rows as $key => $value){
if(strpos($key,"msie") !== false){
$rows["InternetExplorer"] += $value;
unset($rows[$key]);
}
}

I tried hard and searched the internet but I could not find any way.
Of course, I have the ability to move it to the database first and then to the array, but I think there should be a faster way. What do you think?
thanks for reply.
If you have no problem looping through it and flatten the array according to your desire then you can try this:
$parent =
Array
(
[777565] => Array
(
[0] => Array
(
[0] => 777565-1
[1] => 777565-2
)
[1] => Array
(
[0] => 777565-3
[1] => 777565-4
)
[2] => Array
(
[0] => 777565-5
[1] => 777565-6
)
)
[777566] => Array
(
[0] => Array
(
[0] => 777566-1
[1] => 777566-2
)
[1] => Array
(
[0] => 777566-3
[1] => 777566-4
)
[2] => Array
(
[0] => 777566-5
[1] => 777566-6
)
)
);
$length = count($parent);
$result=[];
for($i=0; $i<$length; $i++){
for($j=0; $j<3; $j++){
$l=0;
for($k=0; $k<2; $k++){
$result[777565+$i][$j][$l++] = $parent[777565+$i][$j][$k];
}
}
}

Multidimensional array flattening technique still leaves empty arrays [duplicate]

This question already has answers here:
How to Flatten a Multidimensional Array?
(31 answers)
Closed 7 months ago.
There are many references on S/O showing various methods to flatten a multidimensional recursive array (with more than two levels). I have been through dozens (and tried most) but I'm still running into an odd problem with every one I've tried. What I am getting as a result is:
Array
(
)
Array
(
)
Array
(
)
Array
(
[0] => 1000043
[1] => 1000045
[2] => 1000050
)

Array
(
[0] => 1000030
[1] => 1000032
[2] => 1000058
[3] => 1000064
) ...
But what I'm expecting is a truly flattened single array:
Array
[0] => 1000043
[1] => 1000045
[2] => 1000050
[3] => 1000030
[4] => 1000032
[5] => 1000058
[6] => 1000064
)
The method I found on S/O is supposed to handle an "empty array" (which I assume is the problem) but I'm still getting the wrong output. Here is my code:
function array_flatten5(array $array)
{
$flat = array(); // initialize return array
$stack = array_values($array); // initialize stack
while($stack) // process stack until done
{
$value = array_shift($stack);
if (is_array($value)) // a value to further process
{
$stack = array_merge(array_values($value), $stack);
}
else // a value to take
{
$flat[] = $value;
}
}
return $flat;
}
Could someone point out what I missing here because I'm thinking it's something simple but at this point my eyes are crossed with the number of attempts I've made. Thank you for any help you can provide.
Here is the original array. It is 4-deep:
Array ( [0] => 1000043 [1] => 1000045 [2] => 1000050 ) Array ( [0] => 1000030 [1] => 1000032 [2] => 1000058 [3] => 1000064 ) Array ( [0] => 1000041 [1] => 1000059 [2] => 1000069 ) Array ( [0] => 1000021 [1] => 1000044 [2] => 1000049 [3] => 1000071 ) Array ( [0] => 1000009 [1] => 1000013 [2] => 1000015 [3] => 1000017 [4] => 1000053 ) Array ( [0] => 1000022 [1] => 1000034 [2] => 1000070 ) Array ( [0] => 1000038 [1] => 1000047 [2] => 1000055 [3] => 1000063 ) Array ( [0] => 1000019 [1] => 1000054 [2] => 1000060 [3] => 1000066 [4] => 1000068 ) Array ( [0] => 1000006 [1] => 1000014 [2] => 1000016 [3] => 1000072 ) Array ( [0] => 1000024 [1] => 1000025 [2] => 1000046 [3] => 1000061 [4] => 1000067 ) Array ( [0] => 1000028 [1] => 1000039 [2] => 1000048 ) Array ( [0] => 1000042 [1] => 1000057 ) Array ( [0] => 1000027 [1] => 1000033 [2] => 1000036 [3] => 1000037 ) Array ( [0] => 1000008 [1] => 1000010 [2] => 1000012 [3] => 1000018 ) Array ( [0] => 1000026 [1] => 1000062 [2] => 1000065 ) Array ( [0] => 1000020 [1] => 1000023 [2] => 1000031 [3] => 1000035 [4] => 1000040 ) Array ( [0] => 1000007 [1] => 1000011 [2] => 1000029 ) Array ( [0] => 1000051 [1] => 1000052 [2] => 1000056 ) Array ( [0] => 1000001 [1] => 1000002 [2] => 1000003 [3] => 1000004 [4] => 1000005 ) Array ( [0] => 1000073 )
And here is the outcome using the array_walk_recursive suggestion ...

You didn't prepare suitable array, but looking on this code you need probably just array_walk_recursive() function.
$array = [
[1, 2, 3, 4],
[[5, 6], [7, 8]],
[[[9], [10]], [11]]
];
$result = [];
array_walk_recursive($array, function ($tempV) use (&$result) {
$result[] = $tempV;
});
print_r($result);
Output:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
[5] => 6
[6] => 7
[7] => 8
[8] => 9
[9] => 10
[10] => 11
)

How to convert array first value as key and second value as value

Hi I am working on some array operations.
I need to convert first value of array as key and second value of array as value.
I have one variable $testArray which stores array like below.
Array
(
[0] => Array
(
[0] => Color
[1] => White on Red
)
[1] => Array
(
[0] => Depicted Text
[1] => EMPTY
)
[2] => Array
(
[0] => Depth [Nom]
[1] => 0.004 in
)
[3] => Array
(
[0] => Language
[1] => English
)
[4] => Array
(
[0] => Length [Nom]
[1] => 10 in
)
[5] => Array
(
[0] => Material
[1] => Adhesive Vinyl
)
[6] => Array
(
[0] => Mounting
[1] => Surface
)
[7] => Array
(
[0] => Width [Nom]
[1] => 14 in
)
[8] => Array
(
[0] => Wt.
[1] => 0.056 lb
)
)
Expected output :
Array
(
[0] => Array
(
[Color] => White on Red
)
[1] => Array
(
[Depicted Text] => EMPTY
)
[2] => Array
(
[Depth [Nom]] => 0.004 in
)
[3] => Array
(
[Language] => English
)
[4] => Array
(
[Length [Nom]] => 10 in
)
[5] => Array
(
[Material] => Adhesive Vinyl
)
[6] => Array
(
[Mounting] => Surface
)
[7] => Array
(
[Width [Nom]] => 14 in
)
[8] => Array
(
[Wt.] => 0.056 lb
)
)
I have already tried with array function array_keys and array_values but it won't working
Simple solution using array_map function:
$result = array_map(function($v){
return [$v[0] => $v[1]];
}, $testArray);
Assuming that structure will always be the same, you could do this:
$output = array();
foreach($testArray as $v){
$output[] = array($v[0] => $v[1]);
}
See it in action here.

Multi-dimensional PHP array index

I have this array
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)
[2] => Array
(
[0] => 5
[1] => 6
)
[3] => Array
(
[0] => 7
[1] => 8
)
)
I want this array to be looks like this one:
Array
(
[0] => Array
(
[0] => 1
[1] => 5
)
[1] => Array
(
[0] => 3
[1] => 7
)
[2] => Array
(
[0] => 2
[1] => 6
)
[3] => Array
(
[0] => 4
[1] => 8
)
)
I've spent almost 24 hours to accomplish this task. As you can understand, I need help. Please don't abuse on me by asking what have you tried. Can anyone accomplish this array job? thanks
Edit:
I have this array:
$yourArray = array(
array(1,2),
array(3,4),
array(5,6),
array(7,8),
);
It outputs this one:
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)
[2] => Array
(
[0] => 5
[1] => 6
)
[3] => Array
(
[0] => 7
[1] => 8
)
)
I want $yourArray to outputs this one:
Array
(
[0] => Array
(
[0] => 1
[1] => 5
)
[1] => Array
(
[0] => 3
[1] => 7
)
[2] => Array
(
[0] => 2
[1] => 6
)
[3] => Array
(
[0] => 4
[1] => 8
)
)
Let me write this too, I get output by using print_r($yourArray). And of course by using keyboard. Hope this helps
Considering what OP has made us understand, and quite seriously, I think this is what you're looking for:
$yourArray = array(
array(1,5),
array(3,7),
array(2,6),
array(4,8),
);
var_dump($yourArray);
Demo.
I really can not understand whether it is serious or not.
Explain yourself.
Here you go:
<?php
$array = array(
array(1,2),
array(3,4),
array(5,6),
array(7,8)
);
function processArray(&$array) {
for ($i = 0; $i < count($array); $i++) {
if ($array[$i][0] > 4) {
$array[$i][0] = $array[$i][0] - 3;
}
if ($array[$i][1] < 5) {
$array[$i][1] = $array[$i][1] + 3;
}
}
}
processArray($array);
print_r($array);
Outputs:
Array ( [0] => Array ( [0] => 1 [1] => 5 ) [1] => Array ( [0] => 3 [1] => 7 ) [2] => Array ( [0] => 2 [1] => 6 ) [3] => Array ( [0] => 4 [1] => 8 ) )
I don't see the pattern so the only possibility I see is doing it by hand.
$foo = [
[1,2],
[3,4],
[5,6],
[7,8]
];
$bar = [
[$foo[0][0],$foo[2][0]],
[$foo[1][0],$foo[3][0]],
[$foo[0][1],$foo[2][1]],
[$foo[1][1],$foo[3][1]]
];
print_r($bar);
Edit
Use array() instead of [ ] if you're using an older version of PHP.

PHP Merge array with same keys and one same value

I need to merge a PHP array, this array has 2 arrays into it named "targetXX", I can have 2 or more. Each target have the same keys, for each key I have an array with 2 values a and b, a is always the same in both targets, but I need to merge both B values like this:
Array
(
[0] => Array
(
[target] => hitcount(stats.asdf1.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 1200
[1] => 1392282200
)
[1] => Array
(
[0] => 1400
[1] => 1392282260
)
[2] => Array
(
[0] => 600
[1] => 1392282320
)
[3] => Array
(
[0] => 200
[1] => 1392282380
)
[4] => Array
(
[0] => 400
[1] => 1392282440
)
[5] => Array
(
[0] => 600
[1] => 1392282500
)
)
)
[1] => Array
(
[target] => hitcount(stats.asdf.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 4321
[1] => 1392282200
)
[1] => Array
(
[0] => 76567
[1] => 1392282260
)
[2] => Array
(
[0] => 5556
[1] => 1392282320
)
[3] => Array
(
[0] => 7675
[1] => 1392282380
)
[4] => Array
(
[0] => 2344
[1] => 1392282440
)
[5] => Array
(
[0] => 0999
[1] => 1392282500
)
)
)
Result:
Array
(
[0] => Array
(
[target] => hitcount(stats.asdf1.requests, "1min")
[datapoints] => Array
(
[0] => Array
(
[0] => 1200

)
[1] => Array
(
[0] => 1400
[1] => 1392282260
[2] => 76567
)
[2] => Array
(
[0] => 600
[1] => 1392282320
[2] => 5556
)
[3] => Array
(
[0] => 200
[1] => 1392282380
[2] => 7675
)
[4] => Array
(
[0] => 400
[1] => 1392282440
[2] => 2344
)
[5] => Array
(
[0] => 600
[1] => 1392282500
[2] => 0999
)
)
)
Use array_merge() to achieve this:
$newArray = array();
foreach ($myArray['target2'] as $key => $innerArr1) {
$newArray['target'][$key] = array_merge(
$myArray['target1'][$key], /* 0th and 1st index */
array($innerArr1[1]) /* 2nd index */
);
}
print_r($newArray);
Output:
Array
(
[target] => Array
(
[0] => Array
(
[0] => 333333
[1] => 13
[2] => 99
)
[1] => Array
(
[0] => 444444
[1] => 15
[2] => 98
)
[2] => Array
(
[0] => 555555
[1] => 17
[2] => 97
)
)
)
Demo
The built-in function array_merge may do the work for you. You need to merge each subarrays in fact, as the array_merge_recursive function doesn't handle indexes.
$newArray = array();
foreach ($myArray['target2'] as $key => $arr) {
$newArray['target'][$key] = array_merge($myArray['target1'][$key], $arr[1]);
}
Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.
If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.
If you have more than 2 keys to merge, you can loop on the algorithm multiple times.
