感谢您点击问题。我正在尝试查找并替换包含序列化数组的字符串中的文本。例如:
'fgm2wc_options', 'a:19:{s:15:"automatic_empty";N;s:3:"url";s:25:"http://example.com/store/";s:8:"hostname";s:9:"localhost";s:4:"port";s:4:"3306";s:8:"database";s:22:"apgadmin_store_magento";s:8:"username" ... }
我想将 http://example.com/ 更改为 smth,否则我可以使用 str_replace 来完成,但它不会更改字符串长度指示器(例如 s:25 )。
这是我正在使用的功能:
function recursive_unserialize_replace( $old_url = '', $new_url = '', $data = '', $serialised = false ) {
$new_url = rtrim( $new_url, '/' );
$data = explode( ', ', $data );
try {
if ( is_string( $data ) && ( $unserialized = @unserialize( $data ) ) !== false ) {
$data = recursive_unserialize_replace( $old_url, $new_url, $unserialized, true );
} elseif ( is_array( $data ) ) {
$_tmp = array( );
foreach ( $data as $key => $value ) {
$_tmp[ $key ] = recursive_unserialize_replace( $old_url, $new_url, $value );
}
$data = $_tmp;
unset( $_tmp );
} else {
if ( is_string( $data ) ) {
$data = str_replace( $old_url, $new_url, $data );
}
}
if ( $serialised ) {
return serialize( $data );
}
} catch( Exception $error ) {
}
return $data;
}
有什么想法吗?
对于任何感兴趣的人,这是我想出的解决方案:
function unserialize_replace( $old_url = '', $new_url = '', $database_string = '' ) {
if ( substr( $old_url, -1 ) !== '/' ) {
$new_url = rtrim( $new_url, '/' );
}
$serialized_arrays = preg_match_all( "/a:\d+:.*\;\}+/", $database_string, $matches );
if( !empty( $serialized_arrays ) && is_array( $matches ) ) {
foreach ( $matches[ 0 ] as $match ) {
$unserialized = @unserialize( $match );
if ( $unserialized ) {
$buffer = str_replace( $old_url, $new_url, $unserialized );
$buffer = serialize( $buffer );
$database_string = str_replace( $match, $buffer, $database_string );
}
}
}
if ( is_string( $database_string ) ) {
$database_string = str_replace( $old_url, $new_url, $database_string );
}
return $database_string;
}
感谢您的建议。如果您发现任何问题以及我可以改进的地方,请告诉我
如果不是巨大的结构,我会这样做: 反序列化 - json_encode - 替换 - 解码 - 序列化
