[RESOLVED] searching in text file?

[bull]

so i got txt file:

id|name|age
1|bull|29
2|yoshi|21

3|ivan|29

i want script to do
-search for a strings in file
-when string found in line output this line fields name and age

for example if i wrote in search - ivan
it returns - ivan is 29 years old

if searching - 29
it return bull is 29 years old, ivan is 29 years old

do i need to use strings

$fp = fopen("./text.txt", 'r') ) or die ("error..");
	while (!feof($fp))
	{ $texsts[] = fgets($fp, 1024); }

or array

<?php
$content = file('./some.txt');

and what would the full script be? 😕

You could do something like this:

[Superceded. See later post.

i added line $value='b'; and it returns nothing even if value is ' ' .. why is this/ did i havent done something?

I didn't realize you wanted to match partial strings. Try this:

$content = file('./some.txt'); 
$search_string = strtolower($search_string);
foreach ($content as $value) {
    list($id, $name, $age) = explode('|', trim($value));
    if (($age === (int) $search_string) || (false !== strpos($name, $search_string))) {
        echo ucfirst($name) . ' is ' . $age . ' years old.<br />';
    }
}

BTW "$search_string" is the entered value to search for. "$value" is each individual line of the file you're searching in.

it doesnt work. it every time outputs all lines. it doesnt find needed ones.. where could be the problem?

[Installer]

Well, it works just fine for me. What have you added to it? Post any code you've added.

[bull]

thats what im using. i got textfile with needed fields, but script outputs every line even if it dont fit to search term.

<?
$content = file('./some.txt');
$search_string='debbbbbbbbbb';
$search_string = strtolower($search_string);
foreach ($content as $value) {
list($id, $name, $age) = explode('|', $value);
if (($age == (int) $search_string) || (false !== strpos($name, $search_string))) {
echo ucfirst($name) . ' is ' . $age . ' years old. user id '.$id.'<br />';
}
}
?>

If your text file is laid out as you say (and even if it isn't), you shouldn't be getting every line. As I say, the code works for me, using this file:

id|name|age
1|bull|29
2|yoshi|21
3|ivan|29

Are you sure the code you posted is the code you're running? Because the code you posted works perfectly.

after your last fix it is working properly. where do i need to add text to show if no result is correct. and how to count returned results.

edit. when this - $age === (int) wasnt === it returned Name is age years old. user id id as a first line. when added === it didnt.

This code will avoid matching the heading line, and count the number of matches:

$content = file('./some.txt');
$search_string = strtolower($search_string); 
$ct = 0;
foreach ($content as $value) {
    list($id, $name, $age) = explode('|', $value); 
    if (ctype_digit($id)) {
        if (((int) $age === (int) $search_string) || (false !== strpos($name, $search_string))) { 
            echo ucfirst($name) . ' is ' . $age . ' years old. user id '.$id.'<br />';
            $ct++; 
        }
    }
}
echo $ct . ' match';
if ($ct <> 1) {
    echo 'es';
}
echo ' found.' . '<br />';
