file() and line_num display

[Mark]

Hello all,

I have the following file.txt storing these kind of values:

Name: John Doe
E-mail: jo**@doe.com
Phone: [phone]
Address: 71 Huntington Ln. (33444) FL - Delray Beach US
Member ID: 373732510149005
Registration date: 5/2005
Access code: 6691
Comments: Thanks, great community
============================================
Name: Bill Gates
E-mail: bi*******@owns.microsoft.com
Phone: [phone]
Address: P.O. Box 36 (73456) OK - Leedey USA
Member ID: 5178052509437626
Registration date: 10/2005
Access Code: 969
Comments: Reffered by Josh Portua. Give him credit
============================================
Name: ...... and so on

I want to search the file.txt after 3 predefined Member ID prefixes:
$prefix1="51780";
$prefix2="37373";
$prefix3="72215";
show the Member IDs that match this rule and also display for the found
matching Member IDs their E-mail and Name.

So the search on the part of file.txt shown at the start will result:
Member ID: 5178052509437626 E-mail: bi*******@owns.microsoft.com Name:
Bill Gates

I have built something like this so far:

<?php
$prefix1="51780";
$prefix2="37373";
$prefix3="72215";
$userfile = "users.txt";
$fc=file($userfile);
foreach($fc as $line_num => $line)
{
if (strstr($line,$prefix1))
echo "Found one match at {$line_num} $line<br>";
if (strstr($line,$prefix2))
echo "Found one match at {$line_num} $line<br>";
if (strstr($line,$prefix3))
echo "Found one match at {$line_num} $line<br>";
}
?>

What I can't do is showing the emails and names for the found member
ids. Please, can you give me any suggestions? I'm completly blank.

Thank you for your time.

Regards,
Mark

Mark,

I'd use a database such as MySql or Postgres. They are ideally suited for this
kind of operation. And it's not that hard to program for them.

$prefix2="37373";
$prefix3="72215";
show the Member IDs that match this rule and also display for the found

OK, new script follows:

<?php
$prefix1="51780";
$prefix2="37373";
$prefix3="72215";
$userfile = "users.txt";
$fc=file($userfile);
foreach($fc as $line_num => $line)
{
$line = trim($line); // Line will have newline characters
if (ereg("^E-mail: (.+)", $line, $matches)) {
$email = $matches[1];
}
if (ereg("^Name: (.+)", $line, $matches)) {
$name = $matches[1];
}

if (strstr($line,$prefix1)) {
print "Found ID $prefix1\nName: $name\nEmail: $email\n\n";
}
elseif (strstr($line,$prefix2)) {
print "Found ID $prefix2\nName: $name\nEmail: $email\n\n";
}
elseif (strstr($line,$prefix3)) {
print "Found ID $prefix2\nName: $name\nEmail: $email\n\n";
}
}
?>

This assumes, as per your data that the Name and Email address for a given
member appears before their membership ID.

If not, you'd need to store the ID in the same was as the ereg statements
for name and email and react on reaching the line with all the equals
statements, then see if the ID matches.

I'd agree if he is the one inserting them in to a text file (he may be
being given it by another party).

If he only has the text file, he'd have to parse it either way to insert
it into a DB or to just display it - so he might as well just display it.

Cheers,
Andy

Yes, he would have to parse it *once* to place all the information in the
database. As a flat file he would have to parse it every time he wants anything
from the database. And if the file format ever changes, he'll have to redo the
code every place he needs to access it.

Databases make your life so much simpler - even if you're not inserting into a
file. Even with static data I almost always put the information in a database;
it's just so much easier to access - and you don't run into problems like this.

It depends what he's using the data for. Maybe this is code to parse it
put in to a database? I know at the moment he only wants to print it, but
maybe he's just taking it one step at a time.

To be honest, I think we actually have the same point of view on this, I
completely agree with you - I was just trying to explain (more for the
OP's benefit as I know you're a knowledgeable guy) that a database is a
great end-goal, but if it's for a one-off run it might be easier to just
display the information rather than add an intermediate step.

Your answer to "how do I display these fields" was "use a database"
without the intermediate step of how to get his data from the text file he
has in to the empty database he could make.
Databases make your life so much simpler - even if you're not inserting
into a file. Even with static data I almost always put the information
in a database; it's just so much easier to access - and you don't run
into problems like this.

Again though, while I generally agree - it depends on the purpose.
Without more information from the OP it's difficult for you or I to advise
whether putting it in a database is the best course of action.

For example, this may be a much simplified version of what he wants and it
may just be that his boss has said "here's a one-off dump of the CRM
database, can you get me the details for these users". He's
therefore writing a script to do it (wise man, the boss may ask the same
thing next month) but creating a database would be overkill as it won't be
accessed until possibly next month and by then the data would need
re-importing anyway.

But as I said, without knowing we're both just guessing :-)

Cheers,
Andy

I would like to give a heartly "Thank You!" to Andy Jeffries for
helping me out on this. The script was just what I needed. And you made
a really good point in your replies. I could have used a database but
that was just too much work for something that won't be used intense.
Those dumps appear from time to time and it's no point in having them
stored in a database just for one time use.

Again, Thank you Andy Jeffries for all your help, for your flawless
script and for giving me priceless directions. I was so blanked-out
before and couldn't have imagined a way to solve this.

Best regards,
Mark
