PHP Find Variable in String
Since I always try to remember what this PHP code is, and I can never remember, I thought I’d add it to my blog so I never forget. 
This searches a string of text and finds a user defined variable. Very handy.
$string = "PHP";
$container = "I love writing PHP code.";
if(strstr($container,$string)) {
echo "found it.";
} else {
echo "not found.";
}
Here’s another way to get the same result:
$string = “PHP”;
$container = “I love writing PHP code.”;
echo (strstr($container,$string)?”found it.”:”not found.”);

Hi,
I have used the original method since it allows me to execute certain code based upon found or not found criteria. This article was very helpfull to me.
Thanks

yeah, I don’t know why PHP net always has the complicated jibba jabba when dummies like myself use that site as well. I searched high and low for about ten minutes just now until you solved my problem in laymens terms. Thanks!
