Generally, when the function completes its execution the variable data is deleted automatically by a php script. But sometimes we require those data to continue on another job. In such case, you can use a static variable to do the job.<\/p>\n
By using the static keyword when you first declare the variable will keep the script running even after the code is executed. <\/p>\n
Example code:<\/strong><\/p>\n [php]<?php The code will produce below result.<\/p>\n In the above code, we have a simple function with the static variable Once it is executed the script will use the static variable to display the outcome.<\/p>\n","protected":false},"excerpt":{"rendered":" Generally, when the function completes its execution the variable data is deleted automatically by a php script.
