Installation via PIE -------------------- [](#installation-via-pie) ``` pie install kjdev/lz4 ``` Configuration ------------- [](#configuration) php.ini: ``` extension=lz4.so ``` Function -------- [](#function) - lz4\_compress — LZ4 compression (block format) - lz4\_uncompress — LZ4 decompression (block format) - lz4\_compress\_frame — LZ4 compression (frame format) - lz4\_uncompress\_frame — LZ4 decompression (frame format) ### lz4\_compress — LZ4 compression [](#lz4_compress--lz4-compression) #### Description [](#description) string **lz4\_compress** ( string *$data* \[ , int *$level* = 0 , string *$extra* = NULL \] ) LZ4 compression. #### Parameters [](#parameters) - *data* The string to compress. - *level* The level of compression (1-12, Recommended values are between 4 and 9). (Default to 0, Not High Compression Mode.) - *extra* Prefix to compressed data. #### Return Values [](#return-values) Returns the compressed data or FALSE if an error occurred. ### lz4\_uncompress — LZ4 decompression [](#lz4_uncompress--lz4-decompression) #### Description [](#description-1) string **lz4\_uncompress** ( string *$data* \[ , long *$maxsize* = -1 , long *$offset* = -1 \] ) LZ4 decompression. #### Parameters [](#parameters-1) - *data* The compressed string. - *maxsize* Allocate size output data. - *offset* Offset to decompressed data. #### Return Values [](#return-values-1) Returns the decompressed data or FALSE if an error occurred. ### lz4\_compress\_frame — LZ4 compression (frame format) [](#lz4_compress_frame--lz4-compression-frame-format) #### Description [](#description-2) string **lz4\_compress\_frame** ( string *$data* \[ , int *$level* = 0 , int *$max\_block\_size* = 0 , int *$checksums* = 0 \] ) LZ4 compression to frame. #### Parameters [](#parameters-2) - *data* The string to compress. - *level* The level of compression (1-12, Recommended values are between 4 and 9). (Default to 0, Not High Compression Mode.) - *max\_block\_size* Maximum uncompressed size of each block. Pass any of the following values: - *LZ4\_BLOCK\_SIZE\_64KB* - *LZ4\_BLOCK\_SIZE\_256KB* - *LZ4\_BLOCK\_SIZE\_1MB* - *LZ4\_BLOCK\_SIZE\_4MB* Any other value will be treated as *LZ4\_BLOCK\_SIZE\_64KB*. - *checksums* Enable/disable frame-level and block-level checksums. Pass a bitwise combination of the following constants: - *LZ4\_CHECKSUM\_FRAME*: frame-level checksum - *LZ4\_CHECKSUM\_BLOCK*: block-level checksum #### Return Values [](#return-values-2) Returns the compressed data or FALSE if an error occurred. ### lz4\_uncompress\_frame — LZ4 decompression (frame format) [](#lz4_uncompress_frame--lz4-decompression-frame-format) #### Description [](#description-3) string **lz4\_uncompress\_frame** ( string *$data* ) LZ4 decompression from frame. #### Parameters [](#parameters-3) - *data* The compressed string. #### Return Values [](#return-values-3) Returns the decompressed data or FALSE if an error occurred. Examples -------- [](#examples) ``` $data = lz4_compress('test'); lz4_uncompress($data); ``` Compress Data ------------- [](#compress-data) ### Default [](#default) ``` $data = lz4_compress('test') ``` [![compress-default](docs/compress-default.png)](docs/compress-default.png) ### Extra prefix data [](#extra-prefix-data) ``` $data = lz4_compress('test', false, 'PREFIX') ``` [![compress-extra](docs/compress-extra.png)](docs/compress-extra.png) Uncompress Data --------------- [](#uncompress-data) ### Default [](#default-1) ``` lz4_uncompress($data); ``` [![uncompress-default](docs/uncompress-default.png)](docs/uncompress-default.png) ### Offset [](#offset) ``` lz4_uncompress($data, 256, 6); ``` [![uncompress-offset](docs/uncompress-offset.png)](docs/uncompress-offset.png) ### Health Score 38 — LowBetter than 85% of packages Maintenance66 Regular maintenance activity Popularity36 Limited adoption so far Community23 Small or concentrated contributor base Maturity24 Early-stage or recently created project Bus Factor1 Top contributor holds 81% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
