Go library for PHP community with convenient functions
Via go get command:
go get github.com/arthurkushman/pgoImagine that you need to write Go code every day and also have a convenient functions in memory from PHP experience
For instance, to store Go code data in storage engines like rdbms, no-sql, key-value etc, you can use serialization functions to serialize Go code to string and unserialize it back from string to Go code:
m := make(map[int]string)
m[0] = "abc"
str, err := pgo.Serialize(m) // str -> "Dv+BBAEC/4IAAQQBDAAACf+CAAEAA2FiYw=="
unserMap := make(map[int]string)
err = pgo.Unserialize(str, &unserMap) // unserMap -> map[int]string{0: "abc"}You can use date function with similar formatting for PHP e.g.:
dateStr := pgo.Date("Y-m-d H:i:s") // 2019-03-28 12:23:03
pgo.Date("j D, M") // 27 Wed, Mar
pgo.Date("Q") // 3 (of 1,2,3,4 quarters)nowMicro := pgo.UnixMicro() // get current unix microseconds
nowMilli := pgo.UnixMilli() // get current unix milliseconds
// get current millis + 3ms
nowMillisPlusThree := pgo.Time(time.Now().Add(time.Millisecond * 3)).Milliseconds()
// get current microseconds + 7μs
nowMicroPlusSeven := pgo.Time(now.Add(time.Microsecond * 7)).Microseconds()replace sub-strings with StrReplace:
subject := "The quick brown fox jumped over the lazy dog"
str, err := pgo.StrReplace([]string{"fox", "dog"}, []string{"cat", "elephant"}, subject)
// and if case-insensitive replace needed - pgo.StrIReplace([]string{"DOG", "QuiCK"}, []string{"fox", "slow"}, subject) Building a http query string:
queryStr := pgo.HTTPBuildQuery(map[string]interface{}{
"foo": "bar",
"bar": "baz",
"s": []string{"1", "foo", "2", "bar", "3", "baz"},
"num": 123,
"bigNum": int64(1238873737737737373),
"amount": 623.937,
"isActive": true,
}) // amount=623.937&bar=baz&bigNum=1238873737737737373&foo=bar&isActive=true&num=123&s=1&s=foo&s=2&s=bar&s=3&s=bazStrip tags with exclusion rules:
html := "<div>Lorem <span>ipsum dolor sit amet</span>, consectetur adipiscing elit, sed do eiusmod <a href=\"http://example.com\">tempor incididunt</a> ut labore <strong>et dolore</strong> magna aliqua.</div>"
str := html.StripTags(html, []string{"a", "span"}) // results in: "Lorem <span>ipsum dolor sit amet</span>, consectetur adipiscing elit, sed do eiusmod <a href=\"http://example.com\">tempor incididunt</a> ut labore et dolore magna aliqua."UPD: As had been stated here - golang/go#22639
There is a very handy "stripTags" function in html/template, then guys from official team as fast as they got dislike on
their negative comment, closed the thread. That is why libs like pgo is appearing and will be move forward/evolve,
bypassing strict rules that sometimes looking nonsence.
Read files with offset/limit:
content, err := pgo.FileGetContents("somefile.txt", 0, 1024)reflexively write to files with:
n, err := pgo.FilePutContents("somefile.txt", strToWrite, pgo.FileAppend)Read from context (via http(s)):
content, err := pgo.FileGetContents("http://google.com", pgo.NewContext())Uploading files from web-forms to your server:
ctx := pgo.NewContext()
ctx.Req = YourReq
ctx.UploadMaxFileSize = 10 << 25
uploaded := ctx.MoveUploadedFile("foo", "/srv/images/pic123.png")Checking for file existence
if pgo.FileExists("file1.txt") == true {
// do something with existent file
}Check if it is file/dir/symlink
if pgo.IsFile("someFile.txt") {
// do something with file
}
if pgo.IsDir("someDir/") {
// do something with dir
}
if pgo.IsLink("someLink") {
// do somthing with symlink
}Check if an array contains an element
pgo.InArray(3, []int{1, 2, 3}) // true
