用php和preg_match进行字母数字排序

Question

I have an array called $itemArray[] that contains a set of strings, such as:

myItem_1,
myItem_2,
myItem_3,
myItem_4,
anotherName_1,
anotherName_2,
anotherName_3,
anotherName_4

I also have the following code that goes through the array and filters out the ones that contain 'myItem'. The loop works, however, it returns results in varied order. Is there a way to sort the result of the array so that it lists them alphanumerically?

foreach($itemArray as $item) {
  if (preg_match('/myItem/',$item))
    echo '$item';
}

I don't have much experience with php and would definitely appreciate the help! Thank you!

PHP supports lots of ways to sort arrays, see how they work here . You could run it as asort($itemArray) .

The right way to solve this is by sorting the array prior to outputting it. Something along the lines of:

asort($itemArray);
foreach($itemArray as $item) {
  if (preg_match('/myItem/',$item))
    array[index++] = $item;
}
