phpsort-go is a Go language port of the PHP sort function.
It provides functionality similar to the sort function used in PHP.
Import the package and use the Sort function:
package main
import (
"github.com/demouth/phpsort-go/v2"
)
func main() {
strings := []string{
"lemon",
"apple",
"0 ",
" 1 ",
" 2 ",
" 3 ",
" 04 ",
" 05",
}
phpsort.Sort(strings)
for _, s := range strings {
println(s)
}
}When using the comparison function:
package main
import (
"github.com/demouth/phpsort-go/v2"
)
func main() {
println(phpsort.ZendiSmartStrcmp("2", "1")) // 1
println(phpsort.ZendiSmartStrcmp("1", "2")) // -1
println(phpsort.ZendiSmartStrcmp(" 10", "2")) // 1
println(phpsort.ZendiSmartStrcmp(" 1", "1")) // 0
println(phpsort.ZendiSmartStrcmp("A", "1")) // 1
}For reference, here's the original sort function in PHP:
<?php
$a = [
'lemon',
'apple',
'0 ',
' 1 ',
' 2 ',
' 3 ',
' 04 ',
' 05',
];
sort($a);
var_dump($a);
/*
array(8) {
[0]=>
string(6) "0 "
[1]=>
string(6) " 1 "
[2]=>
string(6) " 2 "
[3]=>
string(6) " 3 "
[4]=>
string(6) " 04 "
[5]=>
string(6) " 05"
[6]=>
string(5) "apple"
[7]=>
string(5) "lemon"
}
*/Sorting results may differ between PHP7 and PHP8. This is due to the implementation of the following two RFCs:
By default, phpsort-go performs sorting compliant with PHP8. However, by specifying WithPHP7Mode, you can perform sorting that reproduces PHP7 behavior.
Here's an example of how to use it:
package main
import (
"github.com/demouth/phpsort-go/v2"
)
func main() {
strings := []string{
"1.0",
" 1",
"1 ",
"+1.0",
}
phpsort.Sort(strings, phpsort.WithPHP7Mode())
for _, s := range strings {
println(s)
}
// Using `WithPHP7Mode` will produce the following results:
// "1.0"
// " 1"
// "+1.0"
// "1 "
// Note that without WithPHP7Mode, the following results will be produced:
// "1.0",
// " 1",
// "1 ",
// "+1.0",
