sqlsrv_fetch_array() expects parameter 1 to be resource, boolean given - php

Question

I've searched high and low for this and I can't wrap my head around it. I have a form to search Permit Applications. Input your permit number and it runs 3 queries against 3 separate SQL Server views. The queries are almost identical in the same if statement but the last one fails. I've performed a var_dump($query_insp_history) copied the output and run a new query directly in SSMS and it works just fine. Is there some other error checking that will give me more detail other than sqlsrv_fetch_array() expects parameter 1 to be resource, boolean given? I believe I have my parameters setup correctly, please let me know if it should be structured differently.
The // Application Inspection History Section is the part giving me issues. I just can't figure it out as it appears it's setup the same way the other two queries are. I receive the error at this line of code while($row = sqlsrv_fetch_array($sql_insp_history, SQLSRV_FETCH_ASSOC)){
var_dump($sql_insp_history); returns bool(false)
var_dump($query_insp_history); returnsstring(81) "SELECT * FROM my.dbo.vw_Permit_App_Insp_History WHERE (LTRIM(APNO) = '123456')"Again, copying this into SSMS runs correctly...
Thank you in advance.
Here is my code.
<div class="container content">
<form method="POST" name="permit_search" action="">
<input type="number" id="apno" name="apno" class="col-sm-8">
<input type="submit" name="apnosearch" id="apnosearch" value="Submit" class="col-sm-4">

Answer 1

According to its documentation, sqlsrv_query() returns false if it gets an error or a statement resource on success.
You must get in the habit of checking errors in SQL operations, or you'll never know whose woods you stop near, Mr. Frost.
You want something like this:
$sql_permit_info = sqlsrv_query($conn, $query_permit_info);
if ($sql_permit_info === false) {
die( print_r( sqlsrv_errors(), true));
}
while ($row= sqlsrv_fetch_array($sql_permit_info, SQLSRV_FETCH_ASSOC)) {

Answer 2

Something must be incorrect with the View I was using. I pulled the raw SELECT statement out of the view and inserted into my $sql_permint_info and all is working fine now.
