Split string into array regex php - php

Question

I need to split the string bellow into array keys like in this format:
string = "(731) some text here with number 2 (220) some 54 number other text here" convert into:
array(
'731' => 'some text here with number 2',
'220' => 'some 54 number other text here'
);
I have tried:
preg_split( '/\([0-9]{3}\)/', $string );
and got:
array (
0 => 'some text here',
1 => 'some other text here'
);

Answer 1

Code
$string = "(731) some text here with number 2 (220) some 54 number other text here";
preg_match_all("/\((\d{3})\) *([^( ]*(?> +[^( ]+)*)/", $string, $matches);
$result = array_combine($matches[1], $matches[2]);
var_dump($result);
Output
array(2) {
[731]=>
string(28) "some text here with number 2"
[220]=>
string(30) "some 54 number other text here"
}

Description
The regex uses
\((\d{3})\) to match 3 digits in parentheses and captures it (group 1)
\ * to match the spaces in between keys and values
([^( ]*(?> +[^( ]+)*) to match everything except a ( and captures it (group 2)
This subpattern matches exactly the same as [^(]*(?<! ) but more efficiently, based on the unrolling-the-loop technique.
*Notice though that I am interpreting a value field cannot have a ( within. If that is not the case, do tell and I will modify it accordingly.
After that, we have $matches[1] with keys and $matches[2] with values. Using array_combine() we generate the desired array.

Answer 2

Try this:
$string = "(731) some text here with number 2 (220) some 54 number other text here";
$a = preg_split('/\s(?=\()/', $string);//split by spaces preceding the left bracket
$res = array();
foreach($a as $v){
$r = preg_split('/(?<=\))\s/', $v);//split by spaces following the right bracket
if(isset($r[0]) && isset($r[1])){
$res[trim($r[0],'() ')] = trim($r[1]);//trim brackets and spaces
}
}
print_r($res);
Output:
Array
(
[731] => some text here with number 2
[220] => some 54 number other text here
)

If you want to limit it only to those numbers in brackets that have 3 digits, just modify the lookarounds:
$a = preg_split('/\s(?=\([0-9]{3}\))/', $string);

Answer 3

you can try this one,
<?php
$str="(731) some text here (220) some other text here";
echo $str .'<br>';
$arr1=explode('(', $str);
$size_arr=count($arr1);
$final_arr=array();
for($i=1;$i<$size_arr; $i++){
$arr2=explode(')', $arr1[$i]);
$final_arr[$arr2[0]]=trim($arr2[1]);
}
echo '<pre>';
print_r($final_arr);
?>

I try to use the simple syntax. Hope everybody can understand.

I'm pretty sure that defining the keys is not possible, as the regex will add matches coninuously.
I would define 2 regex,
one for the keys:
preg_match_all("/(\()([0-9]*)(\))\s/", $input_lines, $output_array);
you will find your keys in $output_array[2].
And one for the texts (that looks quite the same):
preg_split("/(\()([0-9]*)(\))\s/", $input_line);
After that, you can build your custom array iterating over both.
Make sure to trim the strings in the second array when inserting.

Answer 5

Using preg_replace_callback() you can quickly achieve what you desire (when only parentheses contain 3 digits):
$string = "(731) some text here with number 2 (220) some 54 number other text here";
$array = array();
preg_replace_callback('~(\((\d{3})\))(.*?)(?=(?1)|\Z)~s', function($match) use (&$array) {
$array[$match[2]] = trim($match[3]);
}, $string);
var_dump($array);
Output:
array(2) {
[731]=>
string(28) "some text here with number 2"
[220]=>
string(30) "some 54 number other text here"
}

Answer 6

Maybe you can add PREG_SPLIT_DELIM_CAPTURE flag to preg_split. From preg_split man page (http://php.net/manual/en/function.preg-split.php)
PREG_SPLIT_DELIM_CAPTURE
If this flag is set, parenthesized expression in the delimiter pattern will be captured and returned as well.
So if you change your code to:
$results = preg_split('/\(([0-9]+)\)/s', $data,null,PREG_SPLIT_DELIM_CAPTURE);
You will obtain an array similar to:
Array
(
[0] => KS/M/ 2013/1238
[1] => 220
[2] => 23/12/2013
[3] => 300
[4] =>
[5] => 731
[6] => VALDETE BUZA ADEM JASHARI- PRIZREN, KS
[7] => 526
[8] =>
[9] => 591
[10] =>
[11] => 740
[12] =>
[13] => 540
[14] => DEINA
[15] => 546
[16] =>
[17] => 511
[18] => 3 Preparatet për zbardhim dhe substancat tjera për larje rrobash; preparatet për pastrim, shkëlqim, fërkim dhe gërryerje; sapunët; parfumet, vajrat esencialë, preparatet kozmetike, losionet për flokë, pasta për dhembe
14 Metalet e cmueshme dhe aliazhet e tyre; mallrat në metale të cmueshme ose të veshura me to, që nuk janë përfshire në klasat tjera; xhevahirët, gurët e cmueshëm; instrumentet horologjike dhe kronometrike (për matjen dhe regjistrimin e kohës)
25 Rrobat, këpucët, kapelat
35 Reklamim, menaxhim biznesi; administrim biznesi; funksione zyre
)
What you should do is to loop over the array ignoring first element in that case:
$myArray = array();
$myKey = '';
foreach ($results as $k => $v) {
if ( ($k > 0) && ($myKey == '')) {
$myKey = $v;
} else if ($k > 0) {
$myArray[$myKey] = $v;
$myKey = '';
}
}
