how to write the simple short code for parsing - php

Question

I'm working on my PHP to get the list of time. I'm using DomDocument to get the time, I want to find a way to reduce the code as I have got the 69 tags of time in my get-listing.php script.
if I use this:
$time1 = $xpath->query("*/span[#id='time1']");
$time2 = $xpath->query("*/span[#id='time2']");
$time3 = $xpath->query("*/span[#id='time3']");
$time4 = $xpath->query("*/span[#id='time4']");
$time5 = $xpath->query("*/span[#id='time5']");
$time6 = $xpath->query("*/span[#id='time6']");
$time7 = $xpath->query("*/span[#id='time7']");
...etc until to get time69
$time69 = $xpath->query("*/span[#id='time69']");
It will be too large for me to write the list of code to parsing the time from the time1 tag to time69 tag.

My question is how do you write the simple way to write the code to make it shorter to get the element id of time1 to time69 using with few line of code?
Edit: I'm getting fatal error when I'm trying to print the list of strings.
The error are jumping on this line:
$time{$i} = $xpath->query("*/span[#id='time".$i."']");
It could be this:
echo $time->item(0)->nodeValue;
Fatal error: Cannot use object of type DOMNodeList as array in /home/myusername/public_html/work_on_this.php on line 57
Here is the update code:
for ($i = 1; $i < 70; $i++)
{
$time{$i} = $xpath->query("*/span[#id='time".$i."']");
$array = array(
$time{$i}
);
foreach($array as $time)
{
echo $time->item(0)->nodeValue;
}
}

Answer 1

Update the code to following,
$time_arr = array();
for ($i = 1; $i < 70; $i++){
$time_arr[] = $xpath->query("*/span[#id='time".$i."']");
}
foreach($time_arr as $time){
echo $time->item(0)->nodeValue;
}
I'm adding the values to an array directly in the for loop instead of assigning them separately.
And also foreach should not be within for loop which gets the time value.

Answer 2

Use a for loop:
for ($i = 1; $i < 70; $i++) {
$time{$i} = $xpath->query("*/span[#id = \"time\" . $i]");
}
