How can missing commas in an array declaration lead to syntax errors in PHP?

Missing commas in an array declaration can lead to syntax errors in PHP because PHP expects each element in the array to be separated by a comma. If a comma is missing, PHP will interpret the elements as a single entity, causing a syntax error. To fix this issue, ensure that each element in the array is separated by a comma. Example: 

// Incorrect array declaration
$array = ['apple' 'banana' 'orange'];

// Corrected array declaration
$array = ['apple', 'banana', 'orange'];
