I have a html page contents, that I converted into a string separated by "#".
Example:
(2R)-2-hydroxy#250.181#C15H24NO2#2#1#46#1#11#1.1266#1#18#6
Is there any way to convert each value of these string to convert into a array?
I need an output like this:
$a = (2R)-2-hydroxy
$b = 250.181
$c = C15H24NO2
$d = 2
$e = 1
//etc...
This should work for you:
Just explode() your string and loop through the array. Then you can assign each value to a variable, where you can increment the character.
$str = "(2R)-2-hydroxy#250.181#C15H24NO2#2#1#46#1#11#1.1266#1#18#6";
$arr = explode("#", $str);
$start = "a";
foreach($arr as $v) {
$$start = $v;
$start++;
}
This should work
$array = explode("#", "(2R)-2-hydroxy#250.181#C15H24NO2#2#1#46#1#11#1.1266#1#18#6");
$array [0] = (2R)-2-hydroxy
$array [1] = 250.181

I have a long string variable that contains coordinates
I want to keep each coordinate in a separate cell in the array according to Lat and Lon..
For example. The following string:
string = "(33.110029967689556, 35.60865999564635), (33.093492845160036, 35.63955904349791), (33.0916232355565, 35.602995170206896)";
I want this:
arrayX[0] = "33.110029967689556";
arrayX[1] = "33.093492845160036";
arrayX[2] = "33.0916232355565";
arrayY[0] = "35.60865999564635";
arrayY[1] = "35.63955904349791";
arrayY[2] = "35.602995170206896";
Does anyone have an idea ?
Thanks
Use substr to modify sub string, it allow you to do that with a little line of code.
$array_temp = explode('),', $string);
$arrayX = [];
$arrayY = [];
foreach($array_temp as $at)
{
$at = substr($at, 1);
list($arrayX[], $arrayY[]) = explode(',', $at);
}
print_r($arrayX);
print_r($arrayY);
The simplest way is probably to use a regex to match each tuple:
Each number is a combination of digits and .: the regex [\d\.]+ matches that;
Each coordinate has the following format: (, number, ,, space, number,). The regex is \([\d\.]+,\s*[\d\.]+\).
Then you can capture each number by using parenthesis: \(([\d\.]+),\s*([\d\.]+)\). This will produce to capturing groups: the first will contain the X coordinate and the second the Y.
This regex can be used with the method preg_match_all.
<?php
$string = '(33.110029967689556, 35.60865999564635), (33.093492845160036, 35.63955904349791), (33.0916232355565, 35.602995170206896)';
preg_match_all('/\(([\d\.]+)\s*,\s*([\d\.]+)\)/', $string, $matches);
$arrayX = $matches['1'];
$arrayY = $matches['2'];
var_dump($arrayX);
var_dump($arrayY);

My suggestion, working example here: https://3v4l.org/W99Uu
$string = "(33.110029967689556, 35.60865999564635), (33.093492845160036, 35.63955904349791), (33.0916232355565, 35.602995170206896)";
// Split by each X/Y pair
$array = explode("), ", $string);
// Init result arrays
$arrayX = array();
$arrayY = array();
foreach($array as $pair) {
// Remove parentheses
$pair = str_replace('(', '', $pair);
$pair = str_replace(')', '', $pair);
// Split into two strings
$arrPair = explode(", ", $pair);
// Add the strings to the result arrays
$arrayX[] = $arrPair[0];
$arrayY[] = $arrPair[1];
}
You need first to split the string into an array. Then you clean the value to get only the numbers. Finally, you put the new value into the new array.
<?php
$string = "(33.110029967689556, 35.60865999564635), (33.093492845160036, 35.63955904349791), (33.0916232355565, 35.602995170206896)";
$loca = explode(", ", $string);
$arr_x = array();
$arr_y = array();
$i = 1;
foreach($loca as $index => $value){
$i++;
if ($i % 2 == 0) {
$arr_x[] = preg_replace('/[^0-9.]/', '', $value);
}else{
$arr_y[] = preg_replace('/[^0-9.]/', '', $value);
}
}
print_r($arr_x);
print_r($arr_y);

I have a php string formed by images and corresponding prices like OK Like
$myString = "ddb94-b_mgr3043.jpg,3800,83acc-b_mgr3059.jpg,4100";
I know that if I do:
$myArray = explode(',', $myString);
print_r($myArray);
I will get :
Array
(
[0] => ddb94-b_mgr3043.jpg
[1] => 3800
[2] => 83acc-b_mgr3059.jpg
[3] => 4100
)
But How could I split the string so I can have an associative array of the form?
Array
(
"ddb94-b_mgr3043.jpg" => "3800"
"83acc-b_mgr3059.jpg" => "4100"
)
Easier way to do like below:-
<?php
$myString = "ddb94-b_mgr3043.jpg,3800,83acc-b_mgr3059.jpg,4100";
$chunks = array_chunk(explode(',', $myString), 2); //chunk array into 2-2 combination
$final_array = array();
foreach($chunks as $chunk){ //iterate over array
$final_array[trim($chunk[0])] = trim($chunk[1]);//make key value pair
}
print_r($final_array); //print final array
Output:-https://eval.in/859757
Here is another approach to achieve this,
$myString = "ddb94-b_mgr3043.jpg,3800,83acc-b_mgr3059.jpg,4100,test.jpg,12321";
$arr = explode(",",$myString);
$temp = [];
array_walk($arr, function($item,$i) use (&$temp,$arr){
if($i % 2 != 0) // checking for odd values
$temp[$arr[$i-1]] = $item; // key will be even values
});
print_r($temp);
array_walk - Apply a user supplied function to every member of an array
Here is your working demo.
Try this Code... If you will receive all the key and value is equal it will work...
$myString = "ddb94-b_mgr3043.jpg,3800,83acc-b_mgr3059.jpg,4100";
$myArray = explode(',', $myString);
$how_many = count($myArray)/2;
for($i = 0; $i <= $how_many; $i = $i + 2){
$key = $myArray[$i];
$value = $myArray[$i+1];
// store it here
$arra[$key] = $value;
}
print_r($arra);
I have a string of delimited numerical values just like this:
5|2288|502|4208|55|23217|235|10|3845|19053|1885|61|324|9004| ...etc.
Depending on the circumstance, the string may have only 1 value, 15 values, all the way up to 100s of values, all pipe delimited.
I need to count off (and keep/echo) the first 10 values and truncate everything else after that.
I've been looking at all the PHP string functions, but have been unsuccessful in finding a method to handle this directly.
Use explode() to separate the elements into an array, then you can slice off the first 10, and implode() them to create the new string.
$arr = "5|2288|502|4208|55|23217|235|10|3845|19053|1885|61|324|9004";
$a = explode ('|',$arr);
$b = array_slice($a,0,10);
$c = implode('|', $b);
Use PHP Explode function
$arr = explode("|",$str);
It will break complete string into an array.
EG: arr[0] = 5, arr[1] = 2288 .....
I would use explode to separate the string into an array then echo the first ten results like this
$string = "5|2288|502|4208|55|23217|235|10|3845|19053|1885|61|324|9004";
$arr = explode("|", $string);
for($i = 0; $i < 10; $i++){
echo $arr[$i];
}
Please try below code
$str = '5|2288|502|4208|55|23217|235|10|3845|19053|1885|61|324';
$arrayString = explode('|', $str);
$cnt = 0;
$finalVar = '';
foreach ($arrayString as $data) {
if ($cnt > 10) {
break;
}
$finalVar .= $data . '|';
$cnt++;
}
$finalVar = rtrim($finalVar, '|');
echo $finalVar;
I have this two digit number i.e. 50/20 which is seperated by slash and stored in one column of database.
$value = '50/20';
I want to get separate number as
$num1 = 50;
$num2 = 20;
and sum as
$sum = $num1+$num2;
Is there any solution for to separate those combine numbers.
Use explode
Try like this
$value = '50/20';
$arr = explode('/',$value);
$sum = $arr[0]+$arr[1];
//Output
$arr[0] contains 50
$arr[1] contains 20
You can check this by simply doing print_r($arr);
You can do also something like:
$value = '50/20';
$sum = array_sum(explode('/', $value));
echo $sum; // 70
$exp = explode('/',$value);
$value1 = $exp[0];
$value2 = $exp[1];
$sum = $value1 + $value2;
$value = '50/20';
$arr = explode('/',$value);
$num1=$arr[0];
$num2=$arr[1];
$sum=$num1+$num2;
print_r($sum);
Output
70
Explode Function is used to convert a sting to array.
This should work for you.
$value = "50/20";
$numbers = preg_split("/\//",$value);
$sum = $numbers[0]+$numbers[1];
I have this string:
[{"position":"1d","number":10,"nb_plot1":12,"max_actions":3}
{"position":"2d","number":7,"nb_plot1":15,"max_actions":30}
{"position":"3d","number":100,"nb_plot1":2,"max_actions":5}]
and i need to obtain two different string with different format like this:
for numbers:
[10,7,100]
for positions:
['1d','2d','3d']
and cut unnecesarry strings.
I'm a noob sorry.
Decode the string in a array with json_decode.
Iterate over this array and build new arrays for numbers and position.
Encode the arrays.
In code:
$arr = json_decode($string);
$numbers = array();
$positions = array();
foreach($arr as $a)
{
$numbers[] = (int)$a->number;
$positions[] = $a->position;
}
$number_string = json_encode($numbers);
$position_string = json_encode($positions);
