If you have a PHP Array and want to perform some javascript operations by looping the PHP Array, then I recommend you to use PHP foreach loop instead of Javascript forEach loop.
function myfunction() {
<?php foreach($myArray as $val) { ?>
console.log('<?=$val;?>');
<?php } ?>
}
Suppose we have two PHP arrays. Now if we want to merge these two array, then there is a function in PHP to do this. Just use the below code to merge two arrays in PHP.
$combinedArray = array_merge($firstArray, $secondArray);
The above code will return a new combined array of the two arrays.
Now if we want to sort this new array, then :
foreach($combinedArray AS $val) {
$dates[] = strtotime($val['date']); // here 'date' is the key in our $firstArray and $secondArray and our new array will be sorted according to this.
}
array_multisort($dates, SORT_ASC, $combinedArray);
Note :- Both the arrays $firstArray and $secondArray must have the ‘date’ key, because the new array $combinedArray will be sorted according to this.
Using SQL IN operator with PHP array
Suppose we have a array named ‘id_array’ which contains id’s. Now, in order to get all the records from our MySQL table using this array of id, we can use the below given code :
SELECT * FROM TABLE WHERE id IN (".implode(',',$id_array).")
