Calling Variables In A Variable

PHP
1

Hi All

It has been a very long time since I have done any coding and am trying to do something that I think may have changed.

I have a variable with a pile of text in it… in that text there are variables that need to be entered depending on the if else statements.

EXAMPLE

$examplecontent = 'It is ' . $cost . ' to buy this in ' . $currency . ' to ship to your ' . $country . '.';

if ($countrycode == "AU")
 {

$cost = "$1";
$currency = "AUD";
$country = "Australia";

echo (' ' . $examplecontent . '');

}

if ($countrycode == "UK")
 {

$cost = "£1";
$currency = "GBP";
$country = "United Kingdom";

echo (' ' . $examplecontent . '');

}

if ($countrycode == "US")
 {

$cost = "$1";
$currency = "USD";
$country = "United States of America";

echo (' ' . $examplecontent . '');

}

and so on.

I cannot get the variables to call into the echoed variable.

I am sure this is an easy fix but having troubles.

Any help would be great.

Thanks

Try setting error_reporting(-1); and ini_set(‘display_errors’, ‘true’); at the top of the script.

It should show a syntax error with the " in the echo statement.

Edit:
Corrected spelling mistake.

Thanks for that… the errors are that the variables are not defined yet, as per the above example, it is saying that the $cost, $currency and $country variables have not been set yet.

Any idea how to fix this?

Before setting ‘$exampleContent‘ set the the variable to something like $cost = 'default';

The variables should be over written after the if tests.

5

Good idea but nothing is being overwritten… essentially it is reading:

It is to buy this in to ship to your.

Any other ideas?

6

The above statement is unnecessarily repeated and can be omitted until after all the tests.

Also before and after the tests echo each and every variable followed by die;

Ensure every variable is what is expected. Continue until problem is resolved.

Don’t forget to keep error reporting and showing all errors and warnings.

There are no errors but it is not working the way I want it.

I have added default variables at the top and it is just pulling in that info but it is pulling the correct if else statements.

This should be working, I think, but it isn’t… anyone else have any ideas?

Can you try forcing the $country code. also trying again with blank spaces before and after $countrycode?

Also try var_dunp( $countrycode );

It is also easier to add line numbers to displayed variables.

echo '<br>' .__line__ .' ==> '  .$countrycode; die;

Back on the desktop:

<?php 
declare(strict_types=1);

error_reporting(-1);
ini_set('display_errors', 'true');

# DEFAULTS
  $cost         = 'DEFAULT: 001'; 
  $currency     = 'DEFAULT: 002'; 
  $country      = 'DEFAULT: 003'; 
  $countrycode  = '   UK ';

$examplecontent = 'It is ' 
                . $cost 
                . ' to buy this in ' 
                . $currency 
                . ' to ship to your ' 
                . $country . '.';

echo  '<br>BEFORE: '
      .'<br>$code ==> '       .$cost
      .'<br>$currency ==> '   .$currency
      .'<br>$country ==> '    .$country
      .'<br>$countrycode ==> ' .$countrycode
      .'<br>$examplecontent ==> ' .$examplecontent;

# REMOVE POSSIBLE SPACES
  $countrycode  = trim($countrycode);

if ($countrycode == "AU")
{
  $cost = "$1";
  $currency = "AUD";
  $country = "Australia";
  # echo (' ' . $examplecontent . '');
}


if ($countrycode == "UK")
{
  $cost = "£1";
  $currency = "GBP";
  $country = "United Kingdom";
  # echo (' ' . $examplecontent . '');
}

if ($countrycode == "US")
{
  $cost = "$1";
  $currency = "USD";
  $country = "United States of America";
  # echo (' ' . $examplecontent . '');
}

# FINISHED
  $examplecontent = 'It is ' 
                . $cost 
                . ' to buy this in ' 
                . $currency 
                . ' to ship to your ' 
                . $country . '.';

echo  '<br><br>AFTER: '
      .'<br>$code ==> '       .$cost
      .'<br>$currency ==> '   .$currency
      .'<br>$country ==> '    .$country
      .'<br>$countrycode ==> ' .$countrycode
      .'<br>$examplecontent ==> ' .$examplecontent;

**Output:** ``` BEFORE: $code ==> DEFAULT: 001 $currency ==> DEFAULT: 002 $country ==> DEFAULT: 003 $countrycode ==> UK $examplecontent ==> It is DEFAULT: 001 to buy this in DEFAULT: 002 to ship to your DEFAULT: 003.

AFTER:
$code ==> £1
$currency ==> GBP
$country ==> United Kingdom
$countrycode ==> UK
$examplecontent ==> It is £1 to buy this in GBP to ship to your United Kingdom.

<br>
**Edit:**
Added $examplecontent and amended defaults.

Thanks for all of that… from looking at that example I realised all I needed to do was move my code from the top to the bottom and now it works.
