How To Echo Keys Alongside Values Using parse_str() ?

Hi,

Ok. To begin with this thread, I am using the codes found on:
https://forum.webdeveloper.com/d/399940-parse-str-how-to-echo-the-keys-or-var-names-rather-than-var-values
But this is a different topic altogether and so don’t get confused with the other thread.

Look at these 2 codes. They do the same thing in 2 different ways. They extract the values from the query part of the string and print on your screen.

1.

[code]
$url = ‘https://www.username:[email protected]:8080/dir/subdir/file.php?arg=value1&key=value2#fragment’;

echo $all_queries_and_values = parse_url($url,PHP_URL_QUERY); echo ‘<br>’;

parse_str($all_queries_and_values,$arr1);

print_r($arr1); echo ‘<br>’; //DEVMODE.

echo $arr1[‘arg’]; echo ‘<br>’; //Echoes the Value. Not the Key.
echo $arr1[‘key’]; echo ‘<br>’; //Echoes the Value. Not the Key.
[/code]

2.

[code]
$url = ‘https://www.username:[email protected]:8080/dir/subdir/file.php?arg=value1&key=value2#fragment’;

echo $all_queries_and_values = parse_url($url,PHP_URL_QUERY); echo ‘<br>’;

parse_str($all_queries_and_values,$arr2);

print_r($arr2); echo ‘<br>’; //DEVMODE.
var_dump($arr2); echo ‘<br>’; //DEVMODE.

foreach($arr2 AS $single_query_value)
{
echo $single_query_value; echo ‘<br>’; //Echoes the Value. Not the Key.
}
[/code]

I now want to print on your screen not only the values (like shown on the above 2 codes) but the keys alongside the values like so:

[code]
key=>value
[/code]

How to do this ?
These ain’t working …

**The difference between the below 3 codes are these ….
key=>value
“key”=>”value”
key->value**

[code]
$url = ‘https://www.username:[email protected]:8080/dir/subdir/file.php?arg=value1&key=value2#fragment’;

echo $all_queries_and_values = parse_url($url,PHP_URL_QUERY); echo ‘<br>’;

parse_str($all_queries_and_values,$arr2);

print_r($arr2); echo ‘<br>’; //DEVMODE.
var_dump($arr2); echo ‘<br>’; //DEVMODE.

foreach($arr2 AS $single_query_key=>$single_query_value)
{
echo $single_query_key=>$single_query_value; echo ‘<br>’; //I want it to echo both the Keys and the Values. Not the Key.
}
[/code]

Neither this working …
**_(Note the comment at the bottom) …_**

[code]
$url = ‘https://www.username:[email protected]:8080/dir/subdir/file.php?arg=value1&key=value2#fragment’;

echo $all_queries_and_values = parse_url($url,PHP_URL_QUERY); echo ‘<br>’;

parse_str($all_queries_and_values,$arr2);

print_r($arr2); echo ‘<br>’; //DEVMODE.
var_dump($arr2); echo ‘<br>’; //DEVMODE.

foreach($arr2 AS “”$single_query_key””=>””$single_query_value””)
{
echo “$single_query_key”=>”$single_query_value”; echo ‘<br>’; //I want it to echo both the Keys and the Values. Not the Key.
}
[/code]

**Parse error: syntax error, unexpected token “=>”, expecting “->” or “?->” or “{” or “[” in C:xampphtdocsWorkgulfTemplatesparse_string_TEMPLATE.php on line 90**

Nope! Fail too ….

[code]
echo $all_queries_and_values = parse_url($url,PHP_URL_QUERY); echo ‘<br>’;

parse_str($all_queries_and_values,$arr2);

print_r($arr2); echo ‘<br>’; //DEVMODE.
var_dump($arr2); echo ‘<br>’; //DEVMODE.

foreach($arr2 AS “$single_query_key”->”$single_query_value”)
{
echo “$single_query_key”->”$single_query_value”; echo ‘<br>’; //Echoes the Value. Not the Key.
}
[/code]
