File Searching Help

[AliceH]

Hi guys 🙂

I'm trying to code a function to search a file for an 8 digit number.
I don't even know where to start.

Thanks for any help 🙂

Hi,

You are trying to search IN teh file?

Have a look at [man]fopen[/man], [man]fread[/man], [man]strpos[/man]

The problem is the number will be changing.
So I can't enter the number I want to search for, instead I just have to search for an 8 digit number.

Make sense?

Hi,

You'd have to use a regular expression. Look at [man]ereg[/man]

$string = "a string like 50143672 can be detected";

ereg("[0-9]{8}", $string, $regs) ;

echo $regs[0];
