Does this help, similar query: https://www.codeproject.com/Questions/1233256/What-can-I-do-to-fix-warning-mysqli-fetch-array-ex

Your code is vulnerable to SQL Injection[^]. NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.

PHP: SQL Injection - Manual[^]
PHP: Prepared statements and stored procedures - Manual[^]
