search box

Anon

i'm a bit new to PHP, I'm familiar with PERL, so learning PHP has been somewhat easy, however, i'm trying to figure out how to create a search box, and then search a comma delimited file.

I have the file parsed, and i can print out the whole thing but i want to search for zip code or city name then print out only those results.

I parsed the file like this

$search_this = implode(', ', file("zip.csv"));

print "$search_this";

here is the first line of the csv file if that helps understand what i'm trying to do
it's ordered like this

zip |ignored |zip |city |state

00210,USME0205,00210,Portsmouth,NH

that didn't quite answer my question (or maybe it did and I'm a complete idiot ;-)

what i'm trying to do is parse a comma delimited file, then issue a search on it.

php so far

<?php

$search_this = join(',\n', file("zip.csv"));

echo "<title>Weatherman</title>";
echo "<FORM METHOD=GET>\n";
echo "Enter Zip Code: ";

echo "<INPUT TYPE='text' NAME='Zip'>";
echo "<INPUT TYPE='submit' VALUE='Get Local Weather'>";
echo "</FORM>\n";

echo "$Zip<br>";

?>

first line of csv file

00210,USME0205,00210,Portsmouth,NH

so for example if i were to issue a search for 00210 it would output just the zip code onto the page, what i would like it to do, is then read that line into an array so i can then do something like
if ($search_this[3] == 'Portsmouth') {
do something
}

that make more sense?

sorry if i'm confusing....

have you looked at the explode function?

yeah i have as well as join and implode, join is of course just an alias for implode, but if you will kindly read the reply i made to nightowl you will see my code.

If I'm not mistaken,

$search_this becomes something like

"00210,USME0205,00210,Portsmouth,NH\n\nSECONDLINE\n\nTHIRDLINE...."

why do you want it in a string?

why not set $file_content = file($filename);

and next use $array_search() ?

nightowl

let me explain,

you use array_search, get the pointer of the line in which the value you are looking for is situated and next, you output the whole item

$pointer = array_search($neeldle, $haystack);

echo $file_content[$pointer];

<?php

function find_it($searchfor, $tosearch)
{
for ( loop=0; loop<count($tosearch); loop++ )
{
if ( strstr($tosearch, $searchfor) )
{
return(loop);
}
}
return(-1);
}

$filename=getcwd()."/zip.csv";
$fpr=fopen($filename, "r") or die();
$search_this = explode("\n", fread($fpr, filesize($filename)));
fclose($fpr);

$foundat=find_it($needle, $search_this);
if ( $foundat != -1 )
{
echo "Code found on line ".$foundat;
$info=explode(",", $search_this[$foundat];
}
else
{
echo "Cannot find code";
}

as mentioned in my other reply : why not use array_search?
