I have a list of strings like this
A45618416541548234
A48432185120148084
A15973357048208202
I want to split these strings and put them into arrays like this
Array
(
[0] => Array
(
[0] => A45
[1] => 6184165
[2] => 41548234
)
[1] => Array
(
[0] => A48
[1] => 4321851
[2] => 20148084
)
[2] => Array
(
[0] => A15
[1] => 9733570
[2] => 48208202
)
)
I want to split the strings into 3 parts - 1st to 3rd character, 4th to 10th, and 11th to 18th.
I tried doing this using substr, but I could make an array like above...
How can I accomplish this??
You can achieve what you want with array_map and substr:
$strings = array('A45618416541548234', 'A48432185120148084', 'A15973357048208202');
print_r(array_map(function ($v) {
return array(substr($v, 0, 3), substr($v, 3, 7), substr($v, 10, 8)); }
, $strings));
Output:
Array
(
[0] => Array
(
[0] => A45
[1] => 6184165
[2] => 41548234
)
[1] => Array
(
[0] => A48
[1] => 4321851
[2] => 20148084
)
[2] => Array
(
[0] => A15
[1] => 9733570
[2] => 48208202
)
)

I've a muti dimensional array. I want to concatenate 2 strings separately for 2 array values and the 2 strings should not be concatenated for a single value. I want CM and PM concatenated 2 times any where in the array. I've tried looping the array and generating array_rand but i generates only once. Any help is much appreciated. Below is one example of what am achieving.
Thing am trying to achieve
Concatenate "PM" and "CM" string in one set of array and same value can't be CM and PM
Every array should have PM and CM concatenated
1 "Name" value should have minimum 1 CM and PM and Maximum 2 CM and PM
For example: I've the below multi dimensional array.
Array
(
[0] => Array
(
[0] => Name-A
[1] => Name-B
[2] => Name-C
[3] => Name-4
[4] => Name-5
)
[1] => Array
(
[0] => Name-A
[1] => Name-B
[2] => Name-C
[3] => Name-4
[4] => Name-5
)
[2] => Array
(
[0] => Name-A
[1] => Name-B
[2] => Name-C
[3] => Name-4
[4] => Name-5
)
[3] => Array
(
[0] => Name-A
[1] => Name-B
[2] => Name-C
[3] => Name-4
[4] => Name-5
)
[4] => Array
(
[0] => Name-A
[1] => Name-B
[2] => Name-C
[3] => Name-4
[4] => Name-5
)
)
After concatenating
Array
(
[0] => Array
(
[0] => Name-A
[1] => Name-B
[2] => Name-C["PM"]
[3] => Name-4["CM"]
[4] => Name-5
)
[1] => Array
(
[0] => Name-A
[1] => Name-B["PM"]
[2] => Name-C
[3] => Name-4["CM"]
[4] => Name-5
)
[2] => Array
(
[0] => Name-A["PM"]
[1] => Name-B
[2] => Name-C
[3] => Name-4
[4] => Name-5["CM"]
)
[3] => Array
(
[0] => Name-A["PM"]
[1] => Name-B["CM"]
[2] => Name-C
[3] => Name-4
[4] => Name-5
)
[4] => Array
(
[0] => Name-A
[1] => Name-B
[2] => Name-C["CM"]
[3] => Name-4
[4] => Name-5["PM"]
)
)
Sorry I didn't understand at first.
Given $your_array:
// Generate an array where the names are the key, and assign a zero value to PM (0) and CM (1) in a sub array
$ar = array_fill_keys($your_array[0], array (0 => 0, 1 => 0));
//$array the sub_value, $add the case PM ou CM, $exclusion is the key used the first time
function rand_in_array($array, $add, $ar, $exclusion)
{
// Select a random key
$arr_key = array_rand($array, 1);
if($ar[$array[$arr_key]][$add] < 2 && ($arr_key != $exclusion))
{
return $arr_key;
}
return rand_in_array($array, $add, $ar, $exclusion);
}
for($i=0; $i<count($your_array);$i++)
{
$arr_key_pm = rand_in_array($your_array[$i], 0, $ar, 99);
$ar[$your_array[$i][$arr_key_pm]][0]++;
$arr_key_cm = rand_in_array($your_array[$i], 1, $ar, $arr_key_pm);
$ar[$your_array[$i][$arr_key_cm]][1]++;
$your_array[$i][$arr_key_pm] .= "PM";
$your_array[$i][$arr_key_cm] .= "CM";
}
It is ugly but it works :)
Somewhere should existe someone able to make more aesthetic..
for($i=0; $i<count($your_array);$i++)
{
$arr_keys = array_rand($your_array[$i], 2);
$your_array[$i][$arr_keys[0]] .= "PM";
$your_array[$i][$arr_keys[1]] .= "CM";
}
Should do the work.
I assume your inner array index is starting from zero. So generate the random index between 0 to your ( inner_array_size - 1). Then assign the value in the array's reference variable withing the loop.
foreach ($arr as &$value) {
$randomIndex = array_rand(range(0, (count($value) -1) ), 2);
$value[$randomIndex[0]] .= ' ["CM"]';
$value[$randomIndex[1]] .= ' ["PM"]';
}
I'm trying to add a string to a 3*x Array. I have a string as an input with 150*3 values.
<?php
$myString = "5.1,3.5,Red,4.9,3,Blue,4.7,3.2,Red,4.6,3.1,Red,5,3.6,Red," //and so on
?>
the result should look like
Array
(
[0] => Array
(
[0] => 5.1
[1] => 3.5
[2] => Red
)
[1] => Array
(
[0] => 4.9
[1] => 3
[2] => Blue
)
//and so on
)
First, you will need to convert the comma separated string into an array. Then you can use the array_chunk() function.
$myString = "5.1,3.5,Red,4.9,3,Blue,4.7,3.2,Red,4.6,3.1,Red,5,3.6,Red";
$explodedStringToArray = explode(',', $myString);
$chunked_array = array_chunk($explodedStringToArray, 3);
print_r($chunked_array);
This will produce:
Array
(
[0] => Array
(
[0] => 5.1
[1] => 3.5
[2] => Red
)
[1] => Array
(
[0] => 4.9
[1] => 3
[2] => Blue
)
[2] => Array
(
[0] => 4.7
[1] => 3.2
[2] => Red
)
[3] => Array
(
[0] => 4.6
[1] => 3.1
[2] => Red
)
[4] => Array
(
[0] => 5
[1] => 3.6
[2] => Red
)
)
You can use explode() on the string, and then use array_chunk() to chunk the array we have from explode function, keep in mind to check for the chunk size
working snippet: https://3v4l.org/qD1t0
<?php
$myString = "5.1,3.5,Red,4.9,3,Blue,4.7,3.2,Red,4.6,3.1,Red,5,3.6,Red"; //and so on
$arr = explode(",", $myString);
$chunks = array_chunk($Arr, 3);
print_r($chunks);
I have two array two array. First is multidimensional and other is single dimensional. I want to find difference between them. How do I found.
$arrayresult
Array 1
Array (
[0] => Array ( [0] => ishani.lad [1] => 9033187384 )
[1] => Array ( [0] => rajkumar.prajapati [1] => 8460078459 )
[2] => Array ( [0] => lokesh.bhandari [1] => 9687060900 )
[3] => Array ( [0] => shishanshu.rai [1] => 8401915337 )
[4] => Array ( [0] => vishal.dake [1] => 9879815299 )
[5] => Array ( [0] => mohsin [1] => 8347163123 )
)
$useduser
Array 2
Array (
[0] => ishani.lad
[1] => rajkumar.prajapati
[2] => lokesh.bhandari
)
I need difference as result as below
Result
Array (
[0] => Array ( [0] => shishanshu.rai [1] => 8401915337 )
[1] => Array ( [0] => vishal.dake [1] => 9879815299 )
[2] => Array ( [0] => mohsin [1] => 8347163123 )
)
I have used solution as
$resultremainig = [];
foreach($arrayresult as $val2){
if(!in_array($val2[0], $useduser)){
echo $val2[0]."<br>";
$resultremainig[] = $val2;
}
}
But it show last record also. Result of above code is as below. It always show me last record in second array's also
Array (
[0] => Array ( [0] => lokesh.bhandari [1] => 9687060900 )
[1] => Array ( [0] => shishanshu.rai [1] => 8401915337 )
[2] => Array ( [0] => vishal.dake [1] => 9879815299 )
[3] => Array ( [0] => mohsin [1] => 8347163123 )
)
If you wanted you could try using nested loops like so:
<?php
$arrOne = $arrFinal = [
["ishani.lad", 9033187384],
["rajkumar.prajapati", 8460078459],
["lokesh.bhandari" , 9687060900],
["shishanshu.rai" , 8401915337],
["vishal.dake" , 9879815299],
["mohsin" , 8347163123],
];
$arrTwo = [
"ishani.lad",
"rajkumar.prajapati",
"lokesh.bhandari",
];
foreach($arrOne as $key=>$item){
foreach($arrTwo as $k=>$v){
if(in_array($v, $item)){
unset($arrFinal[$key]);
}
}
}
var_dump($arrFinal);
// PRODUCES:::
array (size=3)
3 =>
array (size=2)
0 => string 'shishanshu.rai' (length=14)
1 => int 8401915337
4 =>
array (size=2)
0 => string 'vishal.dake' (length=11)
1 => int 9879815299
5 =>
array (size=2)
0 => string 'mohsin' (length=6)
1 => int 8347163123
You could use array_filter():
$output = array_filter($arrayresult, function($a) use ($useduser) {
return !in_array($a[0], $useduser);
});
Hi You can also try this
$one = array(array('ishani.lad',9033187384),array('rajkumar.prajapati',8460078459),array('lokesh.bhandari',9687060900),array('shishanshu.rai',8401915337),array('vishal.dake',9879815299),array('mohsin',8347163123));
$two = array('ishani.lad','rajkumar.prajapati','lokesh.bhandari');
foreach($one as $array){
if(!in_array($array[0],$two)){
$final[] = $array;
}
}
echo "<pre>";print_r($final);
Output
Array
(
[0] => Array
(
[0] => shishanshu.rai
[1] => 8401915337
)
[1] => Array
(
[0] => vishal.dake
[1] => 9879815299
)
[2] => Array
(
[0] => mohsin
[1] => 8347163123
)
)
Trim the value before checking in $useduser array
$resultremainig = [];
foreach($arrayresult as $val2){
// this removes any extra spaces from the search string
if(!in_array(trim($val2[0]), $useduser)){
echo $val2[0]."<br>";
$resultremainig[] = $val2;
}
You need to use the array_diff function.
Store your 2 arrays in variables and compare them.
I need to extract the values of a condition (WHERE) and did a regex, but I can not get the values correctly.
//Patherns
$regex = "/([a-zA-Z_]+)\s([\<\=\>\s]{0,4})\s+(\".*\")/";
//values to be extracted
$string = 'idCidade >= "bla" OR idEstado="2" and idPais="3"';
//regex function
preg_match_all(
$regex,
$string,
$output
);
//displays the result
echo '<pre>';print_r($output);
//incorrect output
Array
(
[0] => Array
(
[0] => idCidade >= "bla" OR idEstado="2" and idPais="3"
)
[1] => Array
(
[0] => idCidade
)
[2] => Array
(
[0] => >=
)
[3] => Array
(
[0] => "bla" OR idEstado="2" and idPais="3"
)
)
I need the regular expression to export the values to an array like this;
//correct output
Array
(
[0] => Array
(
[0] => idCidade >= "bla" OR idEstado="2" and idPais="3"
)
[1] => Array
(
[0] => idCidade
[1] => idEstado
[2] => idPais
)
[2] => Array
(
[0] => >=
[1] => =
[2] => =
)
[3] => Array
(
[0] => "bla"
[1] => "2"
[2] => "3"
)
[4] => Array
(
[0] => "OR"
[1] => "AND"
[2] => ""
)
)
Your mistake was probably the .* which matches too much. You'd need to make it "ungreedy" with appending a question mark: .*?
I would however suggest this regex:
'/(OR|AND)?\s*(\w+)\s*([<=>!]+)\s*("[^"]*"|\'[^\']*\'|\d+)/i'
This matches the boolean connector first and optionally, so that you get:
[1] => Array
(
[0] =>
[1] => OR
[2] => and
)
[2] => Array
(
[0] => idCidade
[1] => idEstado
[2] => idPais
)
[3] => Array
(
[0] => >=
[1] => =
[2] => =
)
[4] => Array
(
[0] => "bla"
[1] => "2"
[2] => "3"
)
I've also made it work for SQL-compliant strings and decimals. But this is only borderline a job for regex. A real parser would be advisable. (Though I don't know your use case.)
Try this. This outputs the exact result you need.
<?php //Patherns
$regex = '/([a-zA-Z_]+)\s*([>=<]*)\s*"([^"]*)"\s*(or|and)*/i';
//values to be extracted
$string = 'idCidade >= "bla" OR idEstado="2" and idPais="3"';
//regex function
preg_match_all(
$regex,
$string,
$output
);
//displays the result
echo '<pre>';print_r($output);
I have an array like
Array
(
[0] => A
[2] => B
[4] => C
[6] => D
)
I want to remove the first element and then re-index array to get the output
(
[0] => B
[1] => C
[2] => D
)
Which PHP function i need to use?
Update
Input array is
Array
(
[0] => Array
(
[0] => Some Unwanted text
[1] => You crazyy
)
[2] => Array
(
[0] => My belowed text
[1] => You crazyy
)
[10] => Array
(
[0] => My loved quote
[1] => You crazyy
)
)
And the output should be like
Array
(
[0] => Array
(
[0] => My belowed text
[1] => You crazyy
)
[1] => Array
(
[0] => My loved quote
[1] => You crazyy
)
)
You can use
array_shift($array)
Documentation for array_shift
With array_splice.
http://www.php.net/manual/en/function.array-splice.php
php > print_r($input);
Array
(
[0] => A
[2] => B
[4] => C
[6] => D
)
php > array_splice($input, 0, 1);
php > print_r($input);
Array
(
[0] => B
[1] => C
[2] => D
)
we can do it with array_shift() which will remove the 1st index of array and after that use array_values() which will re-index the array values as i did not get from the #User123's answer, try below one:
<?php
$array = array(
0 => "A",
2 => "B",
4 => "C",
6 => "D"
);
array_shift($array);
$array = array_values($array);
echo "<pre>";
print_r($array);
Output: check the output here https://eval.in/837709
Array
(
[0] => B
[1] => C
[2] => D
)
Same for your Updated Input array
<?php
$array = array(
0 => array(
0 => "Some Unwanted text",
1 => "You crazyy"
),
2 => array(
0 => "My belowed text",
1 => "You crazyy"
),
10 => array(
0 => "My loved quote",
1 => "You crazyy"
)
);
array_shift($array);
$array = array_values($array);
echo "<pre>";
print_r($array);
Output: check the output here https://eval.in/837711
Array
(
[0] => Array
(
[0] => My belowed text
[1] => You crazyy
)
[1] => Array
(
[0] => My loved quote
[1] => You crazyy
)
)
You can cut the array as many many index as you want
$newArray = array_splice($oldArray, $startIndex, $lengthToSlice);
$array=array(
0 => 'A',
2 => 'B',
4 => 'C',
6 => 'D'
);
unset($array[0]);
$array = array_values($array);
print_r($array);
This is also another solution to this issue using unset
Output:
Array
(
[0] => B
[1] => C
[2] => D
)
