How to split array in php? - php

Question

I am little bit confused to get first and last value from array. And I tried to use explode()function but my logic is not working properly and very stupid logic.
My array
Array
(
[0] => 500 - 1112
[1] => 1113 - 2224
[2] => 2225 - 4446
[3] => 4446
)
I tried this way
$range = explode(',', $price_range);
$count = count($range);
if (1 == $count) {
$price_1 = $range[0];
$ranges['range1'] = explode(' - ', $price_1);
} else if (2 == $count) {
$price_1 = $range[0];
$price_2 = $range[1];
$ranges['range1'] = explode(' - ', $price_1);
$ranges['range2'] = explode(' - ', $price_2);
} else if (3 == $count) {
$price_1 = $range[0];
$price_2 = $range[1];
$price_3 = $range[2];
$ranges['range1'] = explode(' - ', $price_1);
$ranges['range2'] = explode(' - ', $price_2);
$ranges['range3'] = explode(' - ', $price_3);
} else if (4 == $count) {
$price_1 = $range[0];
$price_2 = $range[1];
$price_3 = $range[2];
$price_4 = $range[3];
$ranges['range1'] = explode(' - ', $price_1);
$ranges['range2'] = explode(' - ', $price_2);
$ranges['range3'] = explode(' - ', $price_3);
$ranges['range4'] = explode(' - ', $price_4);
}
$array = call_user_func_array('array_merge', $ranges);
sort($array);
$min = reset($array);
$max = end($array);
As per my array I want if in array getting single value in array for example
Array
(
[0] => 500 - 1112
[1] => 1113 - 2224
[2] => 2225 - 4446
[3] => 4446
)
So I want to convert this array as shown below,
Array
(
[0] => array(
[0] => 500
[1] => 1112
[2] => 1113
[3] => 2224
[4] => 2225
[5] => 4446
)
[1] => 4446
)
And get min and max from Array ( [0] => array( from this array. Is their any simple way to do.
Thanks in advance

If I correctly understand your example, you provided it with the parameter $count to 2.
So, this could be my version of your request:
The data
<?php
$data[] = '500 - 1112';
$data[] = '1113 - 2224';
$data[] = '4446';
The function
<?php
function explodeRanges(array $data, $counter, $explode = '-') {
$return = [];
// We take the correct number of rows
foreach( array_slice($data, 0, $counter) as $value ) {
$return = array_merge(
$return,
array_map('trim', explode($explode, $value))
);
// trim() function mapped on each elements to clean the data (remove spaces)
// explode all values by the separator
}
return $return;
}
The output
<?php
for( $i = 1 ; $i <= 4 ; $i++ ) {
$range = explodeRanges($data, $i);
echo 'For ', $i, ' => [', implode(', ', $range), ']; MIN = ', min($range), '; MAX = ', max($range);
echo '<hr />';
}
... and the result :)
For 1 => [500, 1112]; MIN = 500; MAX = 1112
For 2 => [500, 1112, 1113, 2224]; MIN = 500; MAX = 2224
For 3 => [500, 1112, 1113, 2224, 4446]; MIN = 500; MAX = 4446
For 4 => [500, 1112, 1113, 2224, 4446]; MIN = 500; MAX = 4446
If you need to repeat your code several times, it's because you can improve it. Here it's quick with a simple function.
