Hello,

I have a handycap because I am comming from Visual Basic 6.
I have been working with PHP for about a month now and and having trouble looking for an "instring" function. Not to mention I don't even know how to start making my own funtion for instring.

What i want to do is

$ArrProduct['strProducy'] = george

$strSearch = "geor"

if ($ArrProduct['strProducy'] == instring($strSearch))
{
echo $ArrProduct['strProducy']."found!"
}
else
{
echo $ArrProduct['strProducy']."not found, Sorry"
}

It would also be equalivant to using % in a SQL Query
WHERE strProduct = "%geor%"

Thank you

It's not the EXACT same as instring, but it WILL return false if the substring is not found, and a value that equals true if it is:

regex is your friend. you can use things like the preg_match() function. there's a regex forum here. mosey on over there.
Did I help you? Feeling generous? Buy me lunch! 
Please, take the time and do some research and find out how much it would have cost you to get your help from a decent paid-for source. A "roll-of-the-dice" freelancer will charge you $5-$15/hr. A decent entry level freelancer will charge you around $15-30/hr. A professional will charge you anywhere from $50-$100/hr. An agency will charge anywhere from $100-$250/hr. Think about all this when soliciting for help here. Think about how much money you are making from the work you are asking for help on. No, we do not expect you to pay for the help given here, but donating a few bucks is a fraction of the cost of what you would have paid, shows your appreciation, helps motivate people to keep offering help without the pricetag, and helps make this a higher quality free-help community :)

No offence Crayon, but you may wan't to refrain from using regex when strstr or strpos can do the same job, as it's mucho faster. It even says so in the manual:

Tip:  Do not use preg_match() if you only want to check if one string is contained in another string. Use strpos() or strstr() instead as they will be faster.
