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
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, Marreplace 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) Bulding a http query string:
queryStr := pgo.HTTPBuildQuery(map[string]string{
"foo": "bar",
"bar": "baz",
}) // bar=baz&foo=barStrip 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/evelove, 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
pgo.InArray("bar33", []string{"foo", "bar", "baz"}) // false
pgo.InArray(3.14159, []float64{33.12, 12.333, 3.14159, 78.4429}) // trueSplit an array by chunks (with auto-tailing)
pgo.ArrayChunk([]int{1, 2, 3, 4, 5, 6, 7, 8}, 2) // [][]int{[]int{1, 2}, []int{3, 4}, []int{5, 6}, []int{7, 8}}
pgo.ArrayChunk([]string{"foo", "bar", "baz", "fizz", "buzz"}, 3) // [][]string{[]string{"foo", "bar", "baz"}, []string{"fizz", "buzz"}}Create an array by using one array for keys and another for its values
pgo.ArrayCombine([]int{11, 32, 13, 14, 51, 46, 17, 88}, []string{"foo", "bar", "baz", "fizz", "buzz", "mazz", "freez", "lorum"})

pgo.ArrayMap([]float64{1, 2, 3, 4, 5}, func(v float64) float64 {

pgo.ArrayDiff([]int{3, 43, 8, 4, 9}, []int{3, 8, 9, 4}) // []int{43}calculate the sum of values in an array

pgo.ArrayIntersect([]int{12, 54, 32, 12, 33}, []int{3, 12, 54, 9}, []int{12, 33, 9}) // []int{12, 54, 33}
pgo.ArrayIntersect([]string{"foo", "bar", "baz", "fizz", "bazz", "fizz", "fizz"}, []string{"bar", "fizz"}, []string{"foo", "bar", "hey"}) // []string{"foo", "bar", "fizz"}creates an int slice of min to max range
pgo.Range(3, 9) // []int{3, 4, 5, 6, 7, 8, 9}
// If a step value is given, it will be used as the increment between elements in the sequence.
pgo.Range(-3, 7, 5) // []int{-3, 2, 7}See more examples in *_test.go files.
long, _ := pgo.IP2long("176.59.34.117") // 2956665461
