Convert data to associated array php - php

Question

Is it possible in php to convert this kind of data
ABANO TERME A001
ABBADIA CERRETO A004
ABBADIA LARIANA A005
ABBADIA SAN SALVATORE A006
ABBASANTA A007
ABBATEGGIO A008
ABBIATEGRASSO A010
to an associated array where in the first column are keys and in the second column are values?

Answer 1

$handle = fopen(path\to\file\filename, "r");
$result_arr = array();
while(($filesop = fgets($handle)) !== false)
{
$line_arr = explode(" ", $filesop);
$value = end($line_arr);
unset($line_arr[array_search($value, $line_arr)]);
$key = implode(" ", $line_arr);
$result_arr[trim($key] = trim($value);
}
print_r($result_arr);
Store in the text file like this (separated by commas):
ABANO TERME,A001
ABBADIA CERRETO,A004
ABBADIA LARIANA,A005
ABBADIA SAN SALVATORE,A006
ABBASANTA,A007
ABBATEGGIO,A008
ABBIATEGRASSO,A010
Solution to read file:
$handle = fopen(path\to\file\filename, "r");
$result_arr = array();
while(($filesop = fgets($handle)) !== false)
{
$line_arr = explode(",", $filesop);
$value = end($line_arr);
unset($line_arr[array_search($value, $line_arr)]);
$key = implode(",", $line_arr);
$result_arr[trim($key] = trim($value);
}
print_r($result_arr);

Answer 2

$txt = file_get_contents('foo.txt');
$arr=array_values(array_filter(explode(' ',$txt)));
$new=[];
for($i=0; $i<count($arr)-1;$i++){
$new[$arr[$i]]=$arr[++$i];
}
print_r($new);

Answer 3

One solution for this particular data would be:
<?php
$data = file_get_contents('data.txt')
//use regular expressions to parse whole file at once
preg_match_all("/([^\s]+\s?[^\s]+?)\s+(.\d+)$/m", $data, $m);
//and combine results from result array ($m)
//first entry - $m[0] contains whole lines thats why I dont use it here
//second entry - $m[1] - data from first brackets is an array key
//third entry - $m[2] - is a value (both are separated by some number of spaces - \s+)
$array = array_combine($m[1], $m[2]);
print_r($array);
?>
output:
Array
(
[ABETONE] => A012
[ABRIOLA] => A013
[ACATE] => A014
[ACCADIA] => A015
)
of course, as colleagues above pointed out, this depends on where data came from, and if this particular set is representative.
