What are the implications of using strpos to determine tables in PHP code, especially when dealing with a large number of tables?

Using strpos to determine tables in PHP code can be inefficient, especially when dealing with a large number of tables. This is because strpos searches for a substring within a string, which can be slow when searching through a large amount of data. Instead, it is recommended to use a more efficient method, such as storing table names in an array and checking against that array. 

$tables = ['table1', 'table2', 'table3'];

if (in_array($tableName, $tables)) {
    // Table exists
} else {
    // Table does not exist
}
