Encode a multidimensional array
This is how you can encode the values of an multidimensional array using two functions. You could of course optimize it to one, by moving the mb_convert_encoding-function into the first condition of the convert2encodingRecursive-function. But in my case I needed the string converter as well.
<?php
/**
* Convert a string to encoding, default UTF-8
*
* @param type $string
* @return type
*/
public function convert2encoding($string, $encoding = "UTF-8") {
return mb_convert_encoding($string, $encoding, mb_detect_encoding($string, "UTF-8, ISO-8859-1, ISO-8859-15", true));
}
/**
* Recursive encoding of multidimensional arrays
* @param type $array
* @param type $encoding
*/
public function convert2encodingRecursive($array, $encoding = "UTF-8") {
if(is_array($array)){
$out = array();
foreach ($array as $key => $value) {
if(is_string($value)){
$out[$key] = $this->convert2encoding($value, $encoding);
}else{
$out[$key] = $this->convert2encodingRecursive($value, $encoding);
}
}
return $out;
}
}
?>This is how you can optimize the above
<?php
replace
$out[$key] = $this->convert2encoding($value, $encoding);
with
$out[$key] = mb_convert_encoding($string, $encoding, mb_detect_encoding($string, "UTF-8, ISO-8859-1, ISO-8859-15", true));
into one function:
public function convert2encodingRecursive($array, $encoding = "UTF-8") {
if(is_array($array)){
$out = array();
foreach ($array as $key => $value) {
if(is_string($value)){
$out[$key] = mb_convert_encoding($string, $encoding, mb_detect_encoding($string, "UTF-8, ISO-8859-1, ISO-8859-15", true));
}else{
$out[$key] = $this->convert2encodingRecursive($value, $encoding);
}
}
return $out;
}
}
