Foreach loop only working on last item - comments

Question

What I'm trying to do is find the URL's in comments and then check those URL's against an array. If the URL is in the array and has the key 'data' with a certain value then I want to replace each URL in the comment with custom text.
I have everything working except the replacing part. This is what I have so far.
the comment
Lorem www.link1.com and ipsum dolor sit amet, http://link2.com consectetur
adipiscing elit. Maecenas http://link3.com eu tempor nibh.
The array the function is using
Array
(
[0] => Array
(
[status] => 200
[data] => one
[url] => www.link1.com
)
[1] => Array
(
[status] => 204
[data] =>
[url] => http://link2.com
)
[2] => Array
(
[status] => 200
[data] => two
[url] => http://link3.com
)
)
the function
function check_the_status( $arrays, $comment ) {
// Bad statis types
$status = apply_filters( 'status_filter', array( 'one', 'two', 'three' ) );
$modified = '';
foreach( $arrays as $key => $array ){
$url = $array['url'];
$data = $array['data'];
if( in_array( $data, $status ) ) {
$modified = '<span>the new text</span>';
$the_comment = str_replace( $url, $modified, $comment );
}
}
return $the_comment;
}
the output
Lorem www.link1.com and ipsum dolor sit amet, http://link2.com consectetur
adipiscing elit. Maecenas "<span>the new text</span>" eu tempor nibh.
So, what's happening with this function, is it's only applying the new text to the last URL in the array, but I want it to be applied to the first and last URL's because they both have the data value I'm checking for in the array. I'm thinking the foreach loop isn't the right way to achieve what I want, but I'm not sure what's the best way.

The problem appears to be with the following line. You are starting over with each iteration by passing $comment each time:
$the_comment = str_replace( $url, $modified, $comment );
You should change it to:
$the_comment = str_replace( $url, $modified, $the_comment );
and intialize $the_comment before the loop:
$the_comment = $comment;
Based on additional comments, here's the working code. I added "bold" style so the result is more pronounced.
$arrays = Array
(
0 => Array
(
'status' => 200,
'data' => 'one',
'url' => 'www.link1.com'
),
1 => Array
(
'status' => 204,
'data' => '',
'url' => 'http://link2.com'
),
2 => Array
(
'status' => 200,
'data' => 'two',
'url' => 'http://link3.com'
)
);
function check_the_status( $arrays, $comment ) {
// Bad statis types
$status = apply_filters( 'status_filter', array( 'one', 'two', 'three' ) );
// The class for targeting the url
$span_class = apply_filters( 'status_class', 'sl-unsafe-link' );
$modified = '';
$the_comment = $comment;
foreach( $arrays as $key => $array ){
$url = $array['url'];
$data = $array['data'];
if( in_array( $data, $status ) ) {
$modified = '<span style="font-weight:bold">'.$url.'</span>';
$the_comment = str_replace( $url, $modified, $the_comment );
}
}
return $the_comment;
}
$comment = 'Lorem www.link1.com and ipsum dolor sit amet, http://link2.com consectetur adipiscing elit. Maecenas http://link3.com eu tempor nibh.';
$new = check_the_status($arrays, $comment);
echo $new;
I ran it locally and this is the output:
Lorem <span style="font-weight:bold">www.link1.com</span> and ipsum dolor sit amet, http://link2.com consectetur adipiscing elit. Maecenas <span style="font-weight:bold">http://link3.com</span> eu tempor nibh.
