Reading and writing and... searching??

[Anon]

I need some help reading a file. I need to find one e-mail address out of a text file. I don't know how to do this. I can open the file but how do I find that one e-mail address? Any ideas would be helpful!

regular expressions.

try ereg()...

I don't totaly understand that function... could you explain it a bit more?

[Anon]

you need to take the manual, try a bit with some code...

[Anon]

Thanks so much for the help!

Try something like this:

Load the file into an array in memory

$my_file = file($filename);

Go through every line

for ($t=0;$tcount($my_file);$t++)
{

Check if the word abc is in this line

if (ereg("abc",$my_file[$t])
{
print "found it\n";
};

};

Do I have to open the file or can I just do it like you showed?

The function file() opens a file, reads it, and stores the content in an array.

So no, you don't have to specifically open the file.
