This article mainly introduces how to use foreach () in PHP to jump out of this or current cycle and terminate the loop. The article is very detailed and has a certain reference value. Interested friends must finish reading it!

PHPforeach () jumps out of this or current loop and terminates the loop method

In the foreach () loop in PHP, you want to be in the loop, when a condition is met, to think

Copy the code

$arr=array ('axiomagy, pachyman, cinema, cinnamon, cinnamon, cinema, cinema, cinnamon, etc.)

$html=''

Foreach ($arras$key= > $value) {

If ($value=='b') {

$html.=$value

Continue;// when $value is b, jump out of this cycle

}

If ($value=='c') {

$html.=$value

Break;// terminates the loop when $value is c

}

$html.=$value

}

Echo$html;// output: ab

Copy the code

Here is a practical example of yourself

/ / parent column

PublicfunctionparentList ($id)

{

/ / query all subcategory data under this column

CategoryData=db ("category")-> where ("id=". $id)-> find ()

/ / dump ($categoryData)

If (! $categoryData) {

$this- > error ("parameter error")

} else {

$this- > assign ('categoryData',$categoryData)

/ / query all subcategory data under this column, namely pid=$id

$category=db ("category")-> select ()

$praProductData=$this- > toLayer ($category)

/ / dump ($praProductData)

Foreach ($praProductDataas$k= > $v) {

/ / if there is a subcategory

If (! empty ($v ['zilei']) & & $v [' id'] = = $id) {

$praductData=Db::table ("ven_article")

-> alias ('a')

-> join ('ven_categoryw','a.cid=w.id')

-> where ("a.statusroom1 and W. piddance'". $id. ")

-> field ("a.idrect a.title.faceimgrect a.timekeeper report.resumerea.cidleg.name")

-> order ('a.idDESC')

-> paginate (6)

/ / dump ($praductData)

Break

} else {

/ / No subclasses

If ($v ['id'] = = $id) {

$praductData=Db::table ("ven_article")

-> alias ('a')

-> join ('ven_categoryw','a.cid=w.id')

-> where ("a.statusroom1anda.cid1" .$ id)

-> field ("a.idrect a.title.faceimgrect a.timekeeper report.resumerea.cidleg.name")

-> order ('a.idDESC')

-> paginate (6)

/ / dump ($praductData)

Break

}

}

}

$data=$praductData- > toArray () ['data']; / / or $data=$praductDatas- > all ()

If ($data) {

$this- > assign ('aura daizen 1)

}

$page=$praductData- > render ()

$this- > assign ('Page',$page)

$this- > assign ("newPraProduct", $praductData)

}

Returnview ("ParentList")

}

The result of printing $praProductData is as follows:

To jump out of this loop and continue to the next loop, or to terminate the foreach () loop when a condition is met, you will use continue and break, respectively.
