In my project, i will have to receive a string from user (in textarea). Now this string will be converted into array. Now the problem is that, the character length must be minimum of 3,
in the following array next element should be joined to current one if character length is less than 3. How to perform it in PHP.
a[0]=>this a[1]=>is a[2]=>an a[3]=>example a[4]=>array.
Output should be:
a[0]=>this a[1]=>isan a[2]=>example a[3]=>array.
Just try with:
$input = ['this', 'is', 'an', 'example', 'array.'];
$output = [];
$part = '';
foreach ($input as $value) {
$part .= $value;
if (strlen($part) > 3) {
$output[] = $part;
$part = '';
}
}
Output:
array (size=4)
0 => string 'this' (length=4)
1 => string 'isan' (length=4)
2 => string 'example' (length=7)
3 => string 'array.' (length=6)

Rearrange words in Array based on position of the first array. In my code there are two array my first array is the base array from which i am going to compare it with second array and make the position same as first array.
Consider 2 input
By considering 1 input as base i am applying levenshtein(metaphone(each word database),metaphone(each word of bank)) then based on that arranging the words of bankdata in new array
databaseName = LAL BAHADUR SHASTRI
bankdata = SHASTRI LAL
source code will only rearrange bankdata and stored in in new array
current output of bankdata : LAL SHASTRI
Rearrangement is happening properly just need to arrange words in array
$db = 'LAL BAHADUR SHASTRI YADAV';
$bank = 'SHASTRI LAL';
$a = reArrangeArray($db,$bank);
function reArrangeArray($db,$bank)
{
$dataBaseName = $db;
$bankdataRows = [$db,$bank,];
$dbWords = preg_split("#[\s]+#", $dataBaseName);
foreach ($bankdataRows as $bankdata)
{
$bankWords = preg_split("#[\s]+#", trim($bankdata));
$result = [];
if(!empty($bankWords))
foreach ($dbWords as $dbWord)
{
$idx = null;
$least = PHP_INT_MAX;
foreach ($bankWords as $k => $bankWord)
if (($lv = levenshtein(metaphone($bankWord),metaphone($dbWord))) < $least)
{
$least = $lv;
$idx = $k;
}
#$result[] = $bankWords[$idx];
unset($bankWords[$idx]);
}
$result = array_merge($result, $bankWords);
var_dump($result);
}
}
Case 1:
CURRENT OUTPUT
array (size=4)
0 => string 'LAL' (length=3)
1 => string 'BAHADUR' (length=7)
2 => string 'SHASTRI' (length=7)
3 => string 'YADAV' (length=5)
array (size=4)
0 => string 'LAL' (length=3)
1 => string 'SHASTRI' (length=7)
2 => null
3 => null
Expected Output
I need array position as same as databaseArray
$dbName = 'LAL BAHADUR SHASTRI YADAV';
$bankName = 'SHASTRI LAL';
array of db (size=4)
0 => string 'LAL' (length=3)
1 => string 'BAHADUR' (length=7)
2 => string 'SHASTRI' (length=7)
3 => string 'YADAV' (length=5)
array of bankname (size=4)
0 => string 'LAL' (length=3)
1 => #
2 => string 'SHASTRI' (length=7)
3 => ###
if word not found in first array it should be place with # since position is 3 which dont have matching element it has 3 #
Case 2
Input :
$dbName = NikithaRani MohanRao
$bankdata = Nikitha Rani Mohan Rao
Output :
$newbankdata = NikithaRani MohanRao
It should concatenate the word if found concatenated in $dbName
<?php
$DatabaseName = "LAL BAHADUR SHASTRI YADAV";
$BankName = "SHASTRI LAL";
$data = explode(" ", $DatabaseName);
$bank = explode(" ", $BankName);
sort($data);
sort($bank);
if($data == $bank){
echo "true";
exit;
}
$lev = 0;
foreach($data as $key => $name){
$lev += levenshtein($name, $bank[$key]);
}
echo PHP_EOL . $lev;
?>
I have a String in this format
{value=very big +$5},{value=super big +$10},{value=extra big +$15}
How to convert them into 2 Arrays in such format?
For example:
$name=["very big","super big","extra big"];
$price=["5","10","15"]; // OR $price=[5,10,15];
I can do that by using explode() if the string format is in a simpler format. However, this format is too complicated. Anyone knows how to do that ?
use explode with ',' ,'=' ,'+$'
$string = "{value=very big +$5},{value=super big +$10},{value=extra big +$15}";
$temp_array = (explode(",",$string));
foreach($temp_array as $val)
{
$temp_array = (explode("=",$val));
$temp_string = $temp_array[1];
$temp_string = str_replace("}","",$temp_string);
$temp_array = (explode("+$",$temp_string));
$name[] = $temp_array[0];
$price[] = $temp_array[1];
}
DEMO
You may try it like the Snippet below suggests. Quick-Test: Here.
<?php
$string = '{value=very big +$5},{value=super big +$10},{value=extra big +$15}';
$arrParts = explode(',', $string);
$name = [];
$price = [];
$result = [];
foreach($arrParts as $iKey=>$part){
$block = preg_replace(["#^\{.*?=#", "#\}$#"], "", $part);
$segments = preg_split("#\s#", $block); //<== CREATE AN ARRAY WITH 3 COLUMNS
list($val1, $val2, $val3) = $segments;
$namePart = $val1 . " {$val2}";
$pricePart = preg_replace("#[\+\-\$]#", "",$val3);
$name[] = $namePart;
$price[] = $pricePart;
// BONUS: JUST CREATE A 3RD ARRAY WITH NAMED-KEY
$result[$namePart] = $pricePart;
}
var_dump($name);
//YIELDS::
array (size=3)
0 => string 'very big' (length=8)
1 => string 'super big' (length=9)
2 => string 'extra big' (length=9)
var_dump($price);
//YIELDS::
array (size=3)
0 => string '5' (length=1)
1 => string '10' (length=2)
2 => string '15' (length=2)
var_dump($result);
//YIELDS::
array (size=3)
'very big' => string '5' (length=1)
'super big' => string '10' (length=2)
'extra big' => string '15' (length=2)
You can use regex, for example this should work:
preg_match_all('/value=([\w\s]+)\s\+/', $string, $matches)
preg_match_all('/\$([\d]+)\}/', $string, $matches)
I am making a function that can help me to cast the string to array, but that strange when the function always add first character to the array. Thank at first and this is code i used in function:
$string = '0:009987;1:12312;2:45231;3:00985;3:10923;4:11253;4:62341;4:01102;4:58710;4:10102;4:87093;4:12034;5:9801;6:1092;6:4305;6:1090;7:450;8:34';
$explodedString = explode(';', $string);
//var_dump($explodedString);
$takeArray = array();
$counti = 0;
foreach($explodedString as $exploded){
$secondExp = explode(':', $exploded);
var_dump($secondExp);
if(isset($takeArray[$secondExp[0]])){
$takeArray[$secondExp[0]][$counti] = $secondExp[1];
}else{
$takeArray[$secondExp[0]] = $secondExp[1];
}
$counti++;
}
var_dump($takeArray);
This is current output of this code:
array (size=9)
0 => string '009987' (length=6)
1 => string '12312' (length=5)
2 => string '45231' (length=5)
3 => string '00981' (length=5)
4 => string '11253 605181' (length=12)
5 => string '9801' (length=4)
6 => string '1092 41' (length=16)
7 => string '450' (length=3)
8 => string '34' (length=2)
Looking into row 4 you will see the string: '605181', this string come from the first character of each value belong to 4. But i need an output array like this:
[0] => {'009987'},
....
[4] => { '11253', '62341', ...., },
....
Please help me.
I'm not sure why you need $counti. All you need to do is, initialize the $takeArray[$n] if it doesn't exists, and push a new value to it. Something like this:
if(!isset($takeArray[$secondExp[0]])) {
// Initialize the array
$takeArray[$secondExp[0]] = array();
}
// Push the new value to the array
$takeArray[$secondExp[0]][] = $secondExp[1];
You only need to do the following :
$takeArray = array();
foreach($explodedString as $exploded) {
$secondExp = explode(':', $exploded);
$takeArray[(int)$secondExp[0]][] = $secondExp[1];
}
$string = '0:009987;1:12312;2:45231;3:00985;3:10923;4:11253;4:62341;4:01102;4:58710;4:10102;4:87093;4:12034;5:9801;6:1092;6:4305;6:1090;7:450;8:34';
$explodedString = explode(';', $string);
$takeArray = array();
foreach($explodedString as $exploded)
{
$secondExp = explode(':', $exploded);
$takeArray[$secondExp[0]][] = $secondExp[1];
}
var_dump($takeArray);
I'm using urlencode & urldecode to pass variables trough a html-form.
$info = 'tempId='.$rows['tempID'].'&tempType='.$rows['tempType'].'&dbId='.$rows['ID'];
echo '<input type="hidden" name="rank[]" value="'.urlencode($info).'" >';
Here is what is in $rows
array (size=4)
'ID' => string '110' (length=3)
'tempID' => string '1' (length=1)
'tempType' => string 'temp_first' (length=10)
'pageOrder' => string '0' (length=1)
So $info is
tempId=1&tempType=temp_first&dbId=110
But if i then decode it, it losses 1 parameter. How is this possible?
foreach (explode('&', urldecode($list[$i])) as $chunk) {
$param = explode("=", $chunk);
$tempId = urldecode($param[0]); // template id
$tempType = urldecode($param[1]); // Template type
$dbId = urldecode($param[2]); // database ID
var_dump($param);
}
Output:
array (size=2)
0 => string 'dbId' (length=4)
1 => string '110' (length=3)
Sometime there are even things in the array wich should not be in there, for example instead of temp_first it says tempType. Just the variable name.
I hope you guys can help me
There's no need to explode and process the string manually, you can use parse_str():
parse_str(urldecode($list[$i]), $output);
var_dump($output);
Would output:
array
'tempId' => string '1' (length=1)
'tempType' => string 'temp_first' (length=10)
'dbId' => string '110' (length=3)
try this
$result=array();
foreach (explode('&', urldecode($list[$i])) as $chunk) {
$param = explode("=", $chunk);
$result[$param[0]]=$param[1];
}
var_dump($result);
Could you try this and check the result (I'm groping in the dark though):
//change this <input type="hidden" name="rank[]" value="'.urlencode($info).'" > to
//<input type="hidden" name="urlargs" value="'.urlencode($info).'" >
$values = explode('&',urldecode($_POST['urlargs']));
$arguments = array();
foreach($values as $argument_set){
$data = explode('=',$argument_set);
$arguments[$data[0]] = $data[1];
}
var_dump($arguments);
I believe the problem is in the way you're processing the value
$data=array();
foreach (explode('&', urldecode($list[$i])) as $chunk) {
$param = explode("=", $chunk); //
$data[$param[0]]=$param[1]
}
Instead of grouping all code together, start by putting it in seperate vars and echo the content for debugging. Because you are saying you loose one variable, but the output you show is just one of the variables. What is the var_dump of the other two?
Because your var_dump($param); would output the part before the '=' and after the '=', so indeed i would expect the output to be something like: So which one of these are you missing?
array (size=2)
0 => string 'tempId' (length=6)
1 => string '1' (length=1)
array (size=2)
0 => string 'tempType' (length=8)
1 => string 'temp_first' (length=10)
array (size=2)
0 => string 'dbId' (length=4)
1 => string '110' (length=3)
DEBUG code:
foreach ($list as $row) {
echo 'Full row:: '. $row.'<br>';
//if the data is comming via GET or POST, its already decoded and no need to do it again
$split = explode('&', urldecode($row));
foreach($split as $chunk) {
echo 'Chunk:: '.$chunk.'<br>';
$param = explode('=', $chunk);
echo 'param name:: '.$param[0].'<br>';
echo 'param value:: '.$param[1].'<br>';
}
}
test.php?t=xxx,y=sss
This is how the user inputs data to my script.
How can I get this data as an array inside test.php, and remove the commas?
$temp = explode(',', $_GET['t']);
$t = $temp[0];
$y = substr($temp[1],2);
will get you what you want from the url you gave, however #Tudor Constantin has the best solution.
Edit
This will loop through all however many fields you have. They will finish up in $result in the correct order.
$temp = explode(',', $_GET['t']);
foreach($temp as $var){
if(strpos($var, '=')){
$exp = explode('=', $var);
$result[] = $exp[1];
} else $result[] = $var;
}
then var_dump $result gives this result
array
0 => string 'xxx' (length=3)
1 => string 'sss' (length=3)
2 => string 'ttt' (length=3)
3 => string 'uuu' (length=3)
Edit 2
Or you could try this:-
Say URL is "test.php?t=xxx,y=sss,z=ttt,a=uuu"
$temp = explode(',', $_GET['t']);
$key = array_keys($_GET);
$temp = array_reverse($temp);
$result[$key[0]] = array_pop($temp);
array_reverse($temp);
foreach($temp as $var){
$exp = explode('=', $var);
$result[$exp[0]] = $exp[1];
}
Then var_dump($result); will give you:-
array
't' => string 'xxx' (length=3)
'a' => string 'uuu' (length=3)
'z' => string 'ttt' (length=3)
'y' => string 'sss' (length=3)
By accessing $_GET['t'], you will get the value 'xxx,y=sss' - I think you have to change the URL to something like
test.php?t=xxx&y=sss
So you will be able to access $_GET['t'] and get the value 'xxx' and $_GET['y'] having value 'sss'
You could also send all the parameter values to one variable, separated by '|' for example - then split by that char:
URL would be test.php?array=xxx|sss|ddd|rrr and in test.php you will do:
$arr = explode('|', $_GET['array']);
This way in the $arr variable you will have an array of the values sent (no matter how many are there)
