[RESOLVED] Making a search program with arrays and loops

[Scholar]

Make (in memory) database of musical instruments and database stores.

Base 1 must have:

instrument id
name of the instrument
instrument model
Base 2 must have:

shop id
stores name
stores address
*

input:
The user enters the name of the instrument in the variable at the beginning of the program.

output:
The program broadcasts a list of all the instruments of a similar name and the shops where it is located.

conditions:
Arrays and loops Must be used

I tried doing it by making a MySQL databases from arrays and then using loops on them but was told to just use the arrays and loops and not use MySQL.

This is what I have so far:

<h3>Instrument:</h3> <input type="text" name="Instrument">
<p><input type="submit" name="submit" value="Prodavnice">
<?php
$instrumenti = array (
array (1,"gitara","gibson"),
array (2,"harmonika","hohner"),
array (3,"bubnjevi","tama"),
);
$prodavnice = array (
array (4,"brothers","pijacna_8"),
array (5,"musicshop","knezmihajlova_10"),
array (6,"drums", "kneza_milosa_5"),
);
if ($Instrument = $instrumenti)
 echo "Naziv prodavnice i adresa:" .$prodavnice. "<br>";
       ?>

Any help would be appreciated.

Welcome to PHPBuilder! When posting PHP code, please use the board's [noparse]

[/noparse] bbcode tags as they make your code much easier to read and analyze.

As for your issue, there are several things wrong with this if() statement:

if ($Instrument = $instrumenti)

1. $Instrument is undefined.

2. The '=' operator is an assignment operator; you probably want to be using a comparison operator (see [man]language.operators.comparison[/man]).

3. You can't directly compare a string with an array.

For #3 above, you'll need to write code that loops through every array in the $instrumenti multidimensional array (i.e. using a [man]foreach/man loop) and checks to see if the instrument name matches the one given from the form.

As far as outputting "the shops where it is located," you can't do that based on the data structure given above; there's no relation table that describes the many-to-many relationships between instruments and shops.
