Add a new attribute to an php foreach array
I didn't notice this problem before, but today I found that when I iterated through the array through foreach, the new properties were not added to the array.
Foreach ($tags as $tag) {
$tag ["name"] = "new name"
}
/ / solution 1: use array item references
Foreach ($tags as & $tag) {
$tag ["name"] = "new name"
}
/ / solution two
Foreach ($tags as $index = > $tag) {$tags [$index] ["name"] = "new name"
}
Specify multiple delimiters when PHP splits a string
In the use of PHP Laravel to achieve the blog article multi-tag function, input tags with English commas as delimiters.
However, PHP's string splitter function explode only supports a single delimiter:
$tags = explode (",", $tags_str)
This is not compatible with Chinese commas because it is easy to mistakenly enter Chinese commas when entering Chinese labels.
So divide it in a regular way:
> $tags_str = "php, Kotlin, Android, website"
= > "php, Kotlin, Android, website"
> preg_split ("/ (, |,) /", $tags_str)
= > [
"php"
"Kotlin"
"Android"
"website"
