I have the code:
$txt = "lookSTARTfromhereSTARTagainhere";
$disp = str_split($txt, 4);
for ($b = 0; $b<3; $b++) {
echo "$disp[$b]";
}
which return 'look', 'STAR' 'Tfor' in a text line of 'lookSTARTfromhereSTARTagainhere' my problem is how do i start my text split from 'START' example my result output for text line of 'lookSTARTfromhereSTARTagainhere' after split look like 'from' 'here' 'again' thanks for your time and understanding
it may not be possible by str_split as 'again' has 5 characters. you can get 'from', 'here' by following code.
$txt = "lookSTARTfromhereSTARTagainhere";
$txt = str_replace('look','',$txt);
$txt = str_replace('START','',$txt);
$disp = str_split($txt, 4);
for ($b = 0; $b<3; $b++) {
echo "$disp[$b]";
}
how do i start my text split from 'START'
Simply with explode and array_slice functions:
$txt = "lookSTARTfromhereSTARTagainhere";
$result = array_slice(explode('START', $txt), 1);
print_r($result);
The output:
Array
(
[0] => fromhere
[1] => againhere
)
If your expected output is four letter words from start you can explode on START then remove first item and use str_split to split each array item to four letter words.
$txt = "lookSTARTfromhereSTARTagainhere";
$arr = explode("START", $txt); // Explode on START
unset($arr[0]); // first item is before START, we don't need that.
$res = [];
foreach($arr as $val){
$temp = str_split($val, 4); // Split array item on four letters.
$res = array_merge($res, $temp); // merge the new array with result array
}
var_dump($res);

<?php
$txt = "lookSTARTfromhereSTARTagainhere";
$split = explode("START",$txt);
unset($split[0]);
$first_str = str_split($split[1],4);
$t2 = str_split($split[2],5);
$second_str = $t2[0];
array_push($first_str,$second_str);
print_r($first_str);
?>
output
Array ( [0] => from [1] => here [2] => again )

I have SKU numbers imported from a CSV file into SQL DB.
Pattern look like:
55A_3
345W_1+04B_1
128T_2+167T_2+113T_8+115T_8
I am trying to move all the letters in front of the numbers.
like:
A55_3
W345_1+B04_1
T128_2+T167_2+T113_8+T115_8
My best idea how to do it was to search for 345W and so, and to replace it with W345 and so:
$sku = "345W_1+04B_1";
$B_range_num = range(0,400);
$B_range_let = range("A","Z");
then generating the find and replace arrays
$B_find =
$B_replace =
maybe just using str_replace??
$res = str_replace($B_find,$B_replace,$sku);
Result should be for all SKU numbers
W345_1+B04_1
Any ideas?
You can use preg_replace to do this job, looking for some digits, followed by a letters and one of an _ with digits, a + or end of string, and then swapping the order of the digits and letters:
$skus = array('55A_3',
'345W_1+04B_1',
'128T_2+167T_2+113T_8+115T_8',
'55A');
foreach ($skus as &$sku) {
$sku = preg_replace('/(\d+)([A-Z]+)(?=_\d+|\+|$)/', '$2$1', $sku);
}
print_r($skus);
Output:
Array
(
[0] => A55_3
[1] => W345_1+B04_1
[2] => T128_2+T167_2+T113_8+T115_8
[3] => A55
)
Demo on 3v4l.org
Here I defined a method with specific format with unlimited length.
$str = '128T_2+167T_2+113T_8+115T_8';
echo convertProductSku($str);
function convertProductSku($str) {
$arr = [];
$parts = explode('+', $str);
foreach ($parts as $part) {
list($first, $second) = array_pad(explode('_', $part), 2, null);
$letter = substr($first, -1);
$number = substr($first, 0, -1);
$arr[] = $letter . $number . ($second ? '_' . $second : '');
}
return implode('+', $arr);
}
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 an Array like this
$first = array("10.2+6","5.3+2.2");
I want to convert it like this
$second = array("10+10+6","5+5+5+2+2");
I also want to print out this such as way
10
10
6
5
5
5
2
2
How can I do this?
You can use this preg_replace_callback function:
$first = array("10.2+6", "5.3+2.2");
$second = preg_replace_callback('/\b(\d+)\.(\d+)\b/', function($m){
$_r=$m[1]; for($i=1; $i<$m[2]; $i++) $_r .= '+' . $m[1] ; return $_r; }, $first);
print_r($second);
Output:
Array
(
[0] => 10+10+6
[1] => 5+5+5+2+2
)
We use this regex /\b(\d+)\.(\d+)\b/ where we match digits before and after DOT separately and capture them in 2 captured groups. Then in callback function we loop through 2nd captured group and construct our output by appending + and 1st captured group.
Here's a solution using regular expressions and various functions. There are many ways to accomplish what you're asking, and this is just one of them. I'm sure this could even be improved upon, but here it is:
$first = array("10.2+5","5.3+2.2");
$second = array();
$pattern = '/(\d+)\.(\d)/';
foreach($first as $item){
$parts = explode('+',$item);
$str = '';
foreach($parts as $part){
if(strlen($str)>0) $str .= '+';
if(preg_match_all($pattern, $part, $matches)){
$str .= implode("+", array_fill(0,$matches[2][$i], $matches[1][$i]));
}else{
$str .= $part;
}
}
$second[] = $str;
}
print_r($second);
Output:
Array
(
[0] => 10+10+5
[1] => 5+5+5+2+2
)
<?php
$first = array("10.2+5","5.3+2");
foreach($first as $term)
{
$second="";
$a=explode("+", $term);
$b=explode(".", $a[0]);
$c=$b[0];
for ($i=0;$i<$b[1];$i++)
$second=$second.$c."+";
echo $second.$a[1]."+";
}
?>
I have some values below:
11 12 13.
I need to make an array using this value.
array(11,12,13);
I tried this code below :
$selected is the variable that contain the value 11 12 13 //Special Instruction
foreach($selected as $key=>$val)
{
$sel.=$val;
$sel.=",";
}
$str = rtrim($sel,',');
// echo $str;
$shortlist = array_map('trim', explode(',',$str));
I need help to make an array like array(11,12,13).Any idea?
You can use explode here. split is deprecated in latest version.
$str = "11 12 13";
$array = explode(" ",$str);
try str_split see http://www.php.net/manual/en/function.str-split.php
$str = "111213";
$array = str_split($str, 2);
print_r($array);
output :
Array
(
[0] => 11
[1] => 12
[2] => 13
)
$values = explode(' ', "11 12 13");
// if there is no space, you can do it like this
$strLen = strlen($string);
$i = 0;
while($i < $strLen) {
$myArr[] = substr($string, $i, 2);
$i += 2;
}
print_r($myArr);
$selected = "11 12 13";
print_r (explode(" ",$selected));
I have string:
ABCDEFGHIJK
And I have two arrays of positions in that string that I want to insert different things to.
Array
(
[0] => 0
[1] => 5
)
Array
(
[0] => 7
[1] => 9
)
Which if I decided to add the # character and the = character, it'd produce:
#ABCDE=FG#HI=JK
Is there any way I can do this without a complicated set of substr?
Also, # and = need to be variables that can be of any length, not just one character.
You can use string as array
$str = "ABCDEFGH";
$characters = preg_split('//', $str, -1);
And afterwards you array_splice to insert '#' or '=' to position given by array
Return the array back to string is done by:
$str = implode("",$str);
This works for any number of characters (I am using "#a" and "=b" as the character sequences):
function array_insert($array,$pos,$val)
{
$array2 = array_splice($array,$pos);
$array[] = $val;
$array = array_merge($array,$array2);
return $array;
}
$s = "ABCDEFGHIJK";
$arr = str_split($s);
$arr_add1 = array(0=>0, 1=>5);
$arr_add2 = array(0=>7, 1=>9);
$char1 = '#a';
$char2 = '=b';
$arr = array_insert($arr, $arr_add1[0], $char1);
$arr = array_insert($arr, $arr_add1[1] + strlen($char1), $char2);
$arr = array_insert($arr, $arr_add2[0]+ strlen($char1)+ strlen($char2), $char1);
$arr = array_insert($arr, $arr_add2[1]+ strlen($char1)+ strlen($char2) + strlen($char1), $char2);
$s = implode("", $arr);
print_r($s);
There is an easy function for that: substr_replace. But for this to work, you would have to structure you array differently (which would be more structured anyway), e.g.:
$replacement = array(
0 => '#',
5 => '=',
7 => '#',
9 => '='
);
Then sort the array by keys descending, using krsort:
krsort($replacement);
And then you just need to loop over the array:
$str = "ABCDEFGHIJK";
foreach($replacement as $position => $rep) {
$str = substr_replace($str, $rep, $position, 0);
}
echo $str; // prints #ABCDE=FG#HI=JK
This works by inserting the replacements starting from the end of string. And it would work with any replacement string without having to determine the length of that string.
