PHP Count Substrings Within Strings

PHP substr_count() Function

The php substr_count() function can be used to count occurrences of string within a string of data. For example, examine the string "I like to eat pizza at the eatery.". There are two occurrences of the word eat. Therefore, the substr_count function could be used to count the number of times eat exists within the string.

 $message = "I like to eat pizza at the eatery"; if(substr_count($message, 'eat') > 1){ echo "It exists more than once."; }
