I have those arrays , how to sort by string ? Just I need to sort mulltiple arrays I try sort() but no luck it give me error.
array(1) {
[0]=>
string(2) "10"
}
array(1) {
[0]=>
string(1) "2"
}
array(1) {
[0]=>
string(1) "3"
}
array(1) {
[0]=>
string(1) "4"
}
This is my code now
<?php
$myfiles = glob('articol/*');
foreach($myfiles as $filename){
if(is_file($filename)){
$file = file_get_contents($filename);
$html = $file;
preg_match('/<p class="id" hidden>(.*?)<\/p>/s', $html, $id) // Return 1 or 2 or 3 .... or 10 ;
$idFinal = array($id[1]);
sort($idFinal);
echo "<pre>"; var_dump($idFinal); echo "</pre>";
}
}
?>
The sort() function is right.
$a1 = ["10"];
$a2 = ["2"];
$a3 = ["3"];
$a4 = ["4"];
$array = array_merge($a1, $a2, $a3, $a4);
$new = array_map(function($e) {
return (int) $e;
},$array);
sort($new);
print_r($new);
output
Array
(
[0] => 2
[1] => 3
[2] => 4
[3] => 10
)
// Array ( [0] => 10 ) Array ( [0] => 2 ) Array ( [0] => 3 ) Array ( [0] => 4 ) Array ( [0] => 5 ) Array ( [0] => 6 ) Array ( [0] => 7 ) Array ( [0] => 8 ) Array ( [0] => 9 ) Array ( [0] => 1 )
$mainArray = [
["10"], ["2"],["3"], ["4"],
];
function mergeAndSortArrays($arr) {
$newArr = array_map(function($e) {
return (int) $e[0];
}, $arr);
sort($newArr);
return $newArr;
}
output
Array
(
[0] => 2
[1] => 3
[2] => 4
[3] => 10
)
Here are ways to sort arrays in php
sort() - sort arrays in ascending order
rsort() - sort arrays in descending order
asort() - sort associative arrays in ascending order, according to the value
ksort() - sort associative arrays in ascending order, according to the key
arsort() - sort associative arrays in descending order, according to the value
krsort() - sort associative arrays in descending order, according to the key
Pick one.
$nums = array("10", "2", "5");
sort($nums);
print_r($nums);
//Array ( [0] => 2 [1] => 5 [2] => 10 )
