Are there any potential issues to consider when converting integers into arrays in PHP?

When converting integers into arrays in PHP, one potential issue to consider is that PHP will automatically convert integers to strings when used as keys in an associative array. To avoid this issue, you can explicitly cast the integer to a string before using it as a key in the array. 

$integer = 123;
$array = [];

// Incorrect way - PHP will automatically convert integer to string
$array[$integer] = 'value';

// Correct way - Explicitly cast integer to string
$array[(string)$integer] = 'value';
