Check array for multiple values, and give unique returns

[Solved_]

Beginner here:

 

I have a array with numbers out of a database, and they correspond with words.

 

This is the translation I already know:

1 = bread

2 = pizza

3 = water

ect...

 

Lets's say the array contains the following numbers:

 

$aWords = array (1, 2, 4, 5, 7, 12, 15);

 

Now I want to check if a number is in the array, and then echo a image if it is there, so a bread image for 1, and a pizza image for 2. I used a switch, but this stopped after finding the first case. I can use a lot of if statements but is there not a easier function I can use?

Why not a foreach loop?

[Solved_]

Thanks. I have this code now, which is working.

 

<?php

 

$aWords = array(1, 2, 4, 5, 7, 12, 15);

 

foreach($aWords as $key => $value)

 

{

echo '<img src=('.'http://example.com/imagepath/'.$value.'.jpg'.')/>'.'</br>';

}

?>

One more question:

 

Showing images is easy because I can base the matching on the numbers it self.

 

What if I want to show the word bread for 1, and pizza for 2, ect..?

Build another array containing the relationship. Key = Id, value = Text name.

 

Use $key in your foreach to reference that text name

[Solved_]

I have build this array, but I have really no clue how to finish the coding.

 

$aTranslate = array(

    1  => 'bread',

    2 => 'piza',

    3 => 'water',

4 => 'cornflakes',

5 => 'word5',

6 => 'word6',

7 => 'word7',

8 => 'word8',

9 => 'word9',

 

);

 

What does:

 

foreach($aWords as $key => $value)

 

the relation $aWords as $key => $value mean?

 

If I echo $aTranslate in the foreach I get "array" repeated every time. If I change $key to $aTranslate:  foreach($aWords as $aTranslate => $value)

 

Then it counts from 0 to 5 if I use 6 values in $aWords = array(1, 2, 5, 7, 8, 9);

$aWords = array(1, 2, 4, 5, 7, 12, 15);

$aTranslate = array(
    1 => 'bread',
    2 => 'piza',
    3 => 'water',
    4 => 'cornflakes',
    5 => 'word5',
    6 => 'word6',
    7 => 'word7',
    8 => 'word8',
    9 => 'word9',  
);

foreach($aWords as $key => $value) {
  $alt = '';
  if (isset($aTranslate[$key])) {
    $alt = $aTranslate[$key];
  }
  echo '<img src="http://example.com/imagepath/' . $value . '.jpg" alt="' . $alt . '"><br>';
}

Hi  ignace, thanks for your help,

 

I have tested your code, but it doesn't work the right way. It translates the keys of the first array, i.e: array(1, 2, 4, 5, 7, 12, 15);

 

into the words list

 

  1 => 'bread',

    2 => 'piza',

    3 => 'water',

    4 => 'cornflakes',

    5 => 'word5',

    6 => 'word6',

    7 => 'word7',

    8 => 'word8',

    9 => 'word9', 

 

So the first one is empty, because the key is 0, and then it translates the keys from bread until word6, not the real translation.

 

Any solution?

It's an easy fix. Take a shot at figuring it out.

Thanks! got it,

 

yeah, have to try more myself

 

if (isset($aTranslate[$value])) {

    $alt = $aTranslate[$value];
