I know the $a variable with the tag is not properly formatted, however that's irrelevant to the issue.
The issue is that strpos is looking for a forward slash, /, in the value of each key in the array, but it is not printing.
$a = '<a target="" href="/test/url">test';
$a_expanded = explode("\"", $a);
echo print_r($a_expanded);
foreach($a_expanded as $num => $aspect) {
echo $aspect;
if ($contains_path = strpos($aspect, '/')) {
echo $a_expanded[$num];
}
}
It echos the array and each aspect, but will not echo the string with the forward slashes when found by strpos.
