In my database i have "montuewedthufrisat" in one field.

Here i have a variable thu.

Now i want to check wheather this "thu" is there in that string or not. How do i do that.

Hi!

Try this...

SELECT * FROM table
WHERE field LIKE '%$var%'

%: wildcard
$var: your variable thu/tue

Hope this helps... Cheers!

Thanks Anwar

But this is not what i want.

Ok assume if i don't retrive it from database.

Eg:
I have two variable
$var1 = "montuewedthu";
var2 = "thu";

Now in this how do i check if "thu" exists in $var1

There should be some function for it, I think in VB for this we can use function instrin() I want this ..

Eg 2.
$var1 = "computer";
$var2 = "put";

Now put exists in $var1 . I want to check this if $var2 exists in $var1.

It's urgent pl help

You can check the string like this.
$var1="monthuwedthufri"

if(strstr($var1,'thu'))
{
$var2 = strstr($var1,'thu');
print("string found ".$var2);
}else
{
print("No match found for the string");
}
In this if the string 'thu' exist $var2 will return the string 'thufri'.

Hope this helps

Oh ok...

Try this then:

if ereg($var2, $var1)
{
// It exists
}

Use the eregi() function if you want it to be case insensitive.
