How can PHP array indexes starting at 0 affect coding practices?

When PHP array indexes start at 0, it means that the first element in an array is accessed using index 0 instead of 1. This can affect coding practices by requiring developers to be mindful of this offset when accessing array elements to avoid off-by-one errors. To solve this issue, developers can simply remember to start indexing arrays at 0 and adjust their code accordingly. 

$colors = array("red", "blue", "green");

// Accessing the first element in the array
echo $colors[0]; // Output: red
