Smart explode or something other - php

Question

I have array:
$array = [
'aaa 3',
'bbb 15',
'ccccc 3A',
'dddd 2412',
'eee fff 15',
'ggg 612',
'hhh iiiii 23B',
];
I would like receive:
$name = 'aaa'; $number = '3';
$name = 'bbb'; $number = '15';
$name = 'ccccc'; $number = '3A';
$name = 'dddd'; $number = '2412';
$name = 'eee'; $number = '15';
$name = 'ggg'; $number = '612';
$name = 'hhh iiiii'; $number = '23B';
So I do:
foreach ($array as $item) {
$expl = explode(' ', $item);
$name = $expl[0];
$number = $expl[1];
}
But this not working for eee fff 15 and hhh iiiii 23B, because these names has two parts. How is better way for this?

Answer 1

Use a regex:
<?php
$array = [
'aaa 3',
'bbb 15',
'ccccc 3A',
'dddd 2412',
'eee fff 15',
'ggg 612',
'hhh iiiii 23B',
];
$regex = '#(?<word>.+)\s(?<number>.+)#';
$results = [];
foreach ($array as $line) {
preg_match($regex, $line, $matches);
$results[$matches['word']] = $matches['number'];
}
var_dump($results);
2 capture groups, first is any characters .+, then a space \s, then any characters .+
Output:
array(7) { ["aaa"]=> string(1) "3" ["bbb"]=> string(2) "15" ["ccccc"]=> string(2) "3A" ["dddd"]=> string(4) "2412" ["eee fff"]=> string(2) "15" ["ggg"]=> string(3) "612" ["hhh iiiii"]=> string(3) "23B" }

You need to look at the size of the array and pick only the last for the number and the rest for the name...
foreach ($array as $item) {
$expl = explode(' ', $item);
$name = implode(" ", array_slice($expl,0,-1));
$number = $expl[count($expl)-1];
echo $name."=". $number.PHP_EOL;
}

Bit late to the party but I wanted to throw in my suggestion on how to do this.
If the $number you want is always at the end of the array, then it doesn't matter how big $name is
$newArray = array();
foreach ($array as $item) {
$expl = explode(' ', $item);
//get the size of the array
$last= count($expl)-1;
//get the final element in the array
$number = $expl[$last];
//remove the last element from array
unset($expl[$last]);
//glue it back together
$name = implode(" ",$expl);
//set the name + number in our array
$newArray[]=array('name' => $name,'number'=>$number);
}
print_r($newArray);
//Output:
/* Array (
[0] => Array (
[name] => aaa
[number] => 3
)
[1] => Array (
[name] => bbb
[number] => 15
)
[2] => Array (
[name] => ccccc
[number] => 3A
)
[3] => Array (
[name] => dddd
[number] => 2412
)
[4] => Array (
[name] => eee fff
[number] => 15
)
[5] => Array (
[name] => ggg
[number] => 612
)
[6] => Array (
[name] => hhh iiiii
[number] => 23B
)
)

try this,
foreach ($array as $item) {
$expl = explode(' ', $item);
$division=array_pop($expl);
$name = $expl[0].' '.$expl[1];
$number = $division;
}
