PHP-strpos function

The strpos function in PHP is used to determine whether a string is contained in another string.

For Example

If there is a string A that contains the following words “The cat is sleeping” and you have another string B that contains this “cat”

One could use the strpos function to determine whether string B belongs to any element is string A. In this case the word cat from string B is present in string A


The If Statement

 if( (strpos($A,$B)!==false){

echo “True”;



echo “False”;


Will return True since string B belongs to string A

The common use of this function is to determine the position of the first occurrence of the substring in a string
