(PHP) how can I split a string in multiple strings separated by comma,
like is I have a string "Hello my neighbor",
then after the split process, it should be
("Hello my neighbor","Hello my","Hello neighbor","my neighbor","Hello","my","neighbor")
try this :
<?php
$string = "Hello my neighbor";
$str = explode(" ",$string);
$newArray = [];
$newArray[] = $string;
for($i = 0; $i<count($str); $i++) {
if($i <= 1) {
$newArray[] = $str[$i]." ".$str[$i+1];
if($i != 0) {
$newArray[] = $str[$i-1]." ".$str[$i+1];
}
}
$newArray[] = $str[$i];
}
echo "<pre>";
print_r($newArray);
echo "</pre>";

I got this string
$string = '1:23:health,2:24:mana';
$v = explode(",", $string);
foreach($v as $data)
{
echo $data[0][1];
}
What im looking is to making a "multidimensional string" by exploding ','
Wanna do this:
data[0][0] = 1;
data[0][1] = 23;
data[0][2] = "health";
How can i do this in PHP?
$string = '1:23:health,2:24:mana';
$result = [];
foreach (explode(',', $string) as $step) {
$result[] = explode(':', $step);
}
print_r($result);
An alternative is:
$string = '1:23:health,2:24:mana';
$result = array_chunk(preg_split('/[:,]/', $string), 3);
print_r($result);

I have probably information about whether it is available in PHP to detect a duplicate and a book about not removing it and adding it to -1, -2, -3
Example:
$string = 'H4,H4,H3,WY21W,W5W,W5W,WY21W,W21/5W,W21/5W,W21W,W16W,W5W';
Result:
$output = 'H4,H4-1,H3,WY21W,W5W,W5W-1,WY21W-1,W21/5W,W21/5W-1,W21W,W16W,W5W-2'
$string = 'H4,H4,H3,WY21W,W5W,W5W,WY21W,W21/5W,W21/5W,W21W,W16W,W5W';
$parts = explode(',', $string); // split by comma
$used = []; // array to count the number of occurrences
$result = []; // array to take the "new" elements
foreach($parts as $part) {
if(isset($used[$part])) { // if there is an entry in the counter array already,
// increment it by one,
$used[$part]++;
}
else { // else initialize with 0
$used[$part] = 0;
}
// put part into new array, append -(counter) if counter > 0
$result[] = $part . ($used[$part] ? '-'.$used[$part] : '');
}
echo implode(',', $result); // join together with comma
Pretty much the same as misorude's answer.
<?php
$string = 'H4,H4,H3,WY21W,W5W,W5W,WY21W,W21/5W,W21/5W,W21W,W16W,W5W';
$values = explode(',', $string);
foreach($values as $k => $value)
if($counts[$value] = !isset($counts[$value]) ? 0 : $counts[$value]-1)
$values[$k] = $value . $counts[$value];
print implode(',', $values);
Output:
H4,H4-1,H3,WY21W,W5W,W5W-1,WY21W-1,W21/5W,W21/5W-1,W21W,W16W,W5W-2

I have two arrays.
$a = array("one","two","three");
$b = array ( 0,1,2,3,4,5,6,7,8,9);
Look at the user contributed example in http://www.php.net/manual/en/class.infiniteiterator.php
$obj = new stdClass();
$obj->Mon = "Monday";
$obj->Tue = "Tuesday";
$obj->Wed = "Wednesday";
$obj->Thu = "Thursday";
$obj->Fri = "Friday";
$obj->Sat = "Saturday";
$obj->Sun = "Sunday";
$infinate = new InfiniteIterator(new ArrayIterator($obj));
foreach (new LimitIterator($infinate, 0, 14) as $value ) {
print($value . PHP_EOL);
}
You could create a mapping function and use array_map as follows:
function numToName($num) {
return array("zero","one","two","three","four","five",
"six","seven","eight","nine")[$num];
}
$b = array (0,8,2,3,7,5,6,0,4,1);
$result = array_map("numToName", $b);
print_r($result);

I have a foreach loop in php.
Loop will return 4 diffirent values and i want to display the highest from it.
Specifically, my loop will return array with date and temperature for that day.
The example code for indication:
foreach ($variable as $key => $value) {
$temperature = temprature();
$date = date();
$teploty[$date] = $teplota;
if(!isset($teploty[$date]) > -50) {
$teploty[$date] = $teplota;
}
}
Your code is confusing. This is how you find the highest value in an array of numbers:
$highest = null;
foreach ($numbers as $num) {
if (is_null($highest) || $num > $highest) {
$highest = $num;
}
}
You should be able to adapt this pattern to your code and data.

I have the below given array
Array
(
[0] => 2,3
[1] => 2,3
)
I want to sum up and get result in a variable. E.g. variable a = 4 (2+2=4) and variable b = 6 (3+3=6). I am coding in php.
Use EXPLODE inside foreach
<?php
$yourArr = array('2,3','2,3');
$a = 0;
$b =0;
foreach ($yourArr as $temp)
{
$tempnew = explode(",",$temp);
$a += $tempnew[0];
$b += $tempnew[1];
}
echo "a = ".$a."<br>";
echo "b = ".$b;
?>
Try this
$a = 0;
$b =0;
foreach ($yourArr as $temp)
{
$a += $temp[0];
$b += $temp[1];
}
echo "a = ".$a."<br>";
echo "b = ".$b;
Output
a = 4
b = 6
