How does PHP compare strings with comparison operators?

Question

I\'m comparing strings with comparison operators.

I needs some short of explanations for the below two comparisons and their result.

if(\'ai\' >          


        

Answer 1

PHP will compare alpha strings using the greater than and less than comparison operators based upon alphabetical order.

• In the first example, ai comes before i in alphabetical order so the test of > (greater than) is false - earlier in the order is considered 'less than' rather than 'greater than'.

• In the second example, ia comes after i alphabetical order so the test of > (greater than) is true - later in the order being considered 'greater than'.
