How to use substr_count()
int substr_count ( string $haystack , string $needle [, int $offset= 0 [, int $length ]] )
The substring count php function is very useful when you need to find out if there are instances of a certain string within a string. It counts how many instances are found. If all you need to know is whether or not a certain string is, use an if() statement to check for a number higher than 0.
<?php
if ($cnt = substr_count('onetwo- test 6 yhnos','test')> 0){
echo "yes test is in there $cnt times";
}
if ($cnt = substr_count('onetwo- test 6 yhnos','test')> 0){
echo "yes test is in there $cnt times";
