מצאתי פונקציה של recursive implode ו-recursive implode,
באתר הרשמי של PHP בדף implode (לא בדקתי עוד, אתה מוזמן לנסות):
קוד PHP:
This is a recursive implode function that can be used on multi-dimensional arrays. The explode function has also obeen included.
<?php
// Can implode an array of any dimension
// Uses a few basic rules for implosion:
// 1. Replace all instances of delimeters in strings by '/' followed by delimeter
// 2. 2 Delimeters in between keys
// 3. 3 Delimeters in between key and value
// 4. 4 Delimeters in between key-value pairs
function implodeMDA($array, $delimeter, $keyssofar = '') {
$output = '';
foreach($array as $key => $value) {
if (!is_array($value)) {
$value = str_replace($delimeter, '/'.$delimeter, $value);
$key = str_replace($delimeter, '/'.$delimeter, $key);
if ($keyssofar != '') $key = $key.$delimeter.$delimeter;
$pair = $key.$keyssofar.$delimeter.$delimeter.$delimeter.$ value;
if ($output != '') $output .= $delimeter.$delimeter.$delimeter.$delimeter;
$output .= $pair;
}
else {
if ($output != '') $output .= $delimeter.$delimeter.$delimeter.$delimeter;
if ($keyssofar != '') $key = $key.$delimeter.$delimeter;
$output .= $this->implodeMDA($value, $delimeter, $key.$keyssofar);
}
}
return $output;
}
// Can explode a string created by corresponding implodeMDA function
// Uses a few basic rules for explosion:
// 1. Instances of delimeters in strings have been replaced by '/' followed by delimeter
// 2. 2 Delimeters in between keys
// 3. 3 Delimeters in between key and value
// 4. 4 Delimeters in between key-value pairs
function explodeMDA($string, $delimeter) {
$output = array();
$pair_delimeter = $delimeter.$delimeter.$delimeter.$delimeter;
$pairs = explode($pair_delimeter, $string);
foreach ($pairs as $pair) {
$keyvalue_delimeter = $delimeter.$delimeter.$delimeter;
$keyvalue = explode($keyvalue_delimeter, $pair);
$key_delimeter = $delimeter.$delimeter;
$keys = explode($key_delimeter, $keyvalue[0]);
$value = str_replace('/'.$delimeter, $delimeter, $keyvalue[1]);
$keys[0] = str_replace('/'.$delimeter, $delimeter, $keys[0]);
$pairarray = array($keys[0] => $value);
for ($counter = 1; $counter < count($keys); $counter++) {
$pairarray = array($keys[$counter] => $pairarray);
}
$output = array_merge_recursive($output, $pairarray);
}
return $output;
}
?>
עריכה: מצאתי עוד אחד למקרה שלא יעבוד:
קוד PHP:
<?php
function implode_md( $glue, $array, $key = NULL, $list = NULL )
{
if( !is_array( $array ) )
return $array;
if( !sizeof( $array ) )
return "";
if( !is_null( $key ) )
{
if( strpos( $key, "." ) )
{
$keys = array_reverse( explode( ".", $key ) );
$currentKey = array_pop( $keys );
if( sizeof( $keys ) ) $keys = implode( ".", $keys );
else $keys = implode( "", $keys );
}
else
{
$currentKey = $key;
$keys = NULL;
}
if( array_key_exists( $currentKey, $array ) )
return implode_md( $glue, $array[$currentKey], $keys, $list );
else
return "";
}
if( !empty( $list ) )
{
$last = array_pop( $array );
if( count( $array ) )
return implode_md( $glue, $array, $key ) . " $list $last";
else
return $last;
}
$ret = array();
for( $i = 0; $i < sizeof( $array ); $i++ )
if( is_array( $array[$i] ) ) $ret[] = implode_md( $glue, $array[$i], $key, $list );
else $ret[] = $array[$i];
return implode( $glue, $ret );
}
?>
