get value from exploded string in php - php

Question

I have custom cms database and get parameter from database and my result this is:
$param = 'param1="value1"|param2="value2"|param3="value3"|param4="value4"|param5="value5"'
but I need get param1 value or other value. I try use explode but my result this is:
$string = explode('|',$param);
result:
array (size=4)
0 => string 'param1="value1"'
1 => string 'param2="value2"'
2 => string 'param3="value3"'
3 => string 'param4="value4"'
4 => string 'param5="value4"'
I need get value this format:
$param->param1 = value1;

Answer 1

You also need to explode each of the substrings on =, and then map the results into an array:
$param = 'param1="value1"|param2="value2"|param3="value3"|param4="value4"|param5="value5"';
$params = explode('|', $param);
$results = [];
foreach ($params as $element) {
list($key, $value) = explode('=', $element, 2);
$results[$key] = json_decode($value);
}
echo $results['param1']; // value1
The call to json_decode might look a bit out of place here, but it's the quickest way to convert a quoted string into a native PHP string. The additional argument to the second explode call is to limit the result to two variables, in case the value itself contains an equals sign.

Answer 2

Try parse_str, you can then create an object using the array
<?php
$param = 'param1="value1"|param2="value2"|param3="value3"|param4="value4"|param5="value5"';
$params = array();
parse_str(str_replace('|', '&', $param), $params);
$params = (object) $params;
echo $params->param1;
?>

Nice and easy with a litte regex:
$param = 'param1="value1"|param2="value2"|param3="value3"|param4="value4"|param5="value5"';
$strings = explode('|', $param);
foreach ($strings as $string) {
preg_match('#param\d="(?<value>.+)"#', $string, $matches);
var_dump($matches['value']);
}
The regex #param\d="(?<value>.+)"# looks for param followed by a number then an equals, and we create a named capture group with ?<value> in the brackets.
The output from the var_dumps looks like this:
string(6) "value1"
string(6) "value2"
string(6) "value3"
string(6) "value4"
string(6) "value5"

When you've split the first part using '|', you can convert the rest as though it was a CSV field with '=' as the divider. This deals with quotes and other elements.
<?php
error_reporting ( E_ALL );
ini_set ( 'display_errors', 1 );
$param = 'param1="value1"|param2="value2"|param3="value3"|param4="value4"|param5="value5"';
$parms = explode('|', $param );
$values = [];
foreach ( $parms as $parm ) {
list($key, $value) = str_getcsv($parm, "=");
$values[$key] = $value;
}
print_r($values);

Answer 5

$param = 'param1="value1"|param2="value2"|param3="value3"|param4="value4"|param5="value5"';
$param = json_decode('{"' . str_replace(['=', '|'], ['":', ',"'], $param) . '}');
print_r($param);
This is just example. Don't use it in production :)

Answer 6

Use the following approach:
$param = 'param1="value1"|param2="value2"|param3="value3"|param4="value4"|param5="value5"';
$result = [];
foreach (explode('|', $param) as $item) {
list($k,$v) = explode('=', $item);
$result[$k] = trim($v, '"');
}
$result = (object) $result;
// as you wanted
print_r($result->param1); // value1
