Copy CodeThe code is as follows: $arrF = Array (); $arrS = Array (); $intTotal = 100; $intRand = 10; for ($i =0; $i { $arrF [] = rand (1, $intRand); $arrS [] = rand (1, $intRand); } $arrT = Array_merge ($arrF, $arrS); $arrRF = Array (); $intStart =

Delete the php code of repeated values in the array. When $ intTotal is relatively small, for example, the value of $ intRand within 1000 basically does not affect the result, and the execution time of both is similar. When the value of $ intTotal

Copy code code as follows: $arrF = Array (); $arrS = Array (); $intTotal = 100; $intRand = 10; for ($i =0; $i { $arrF [] = rand (1, $intRand); $arrS [] = rand (1, $intRand); } $arrT = Array_merge ($arrF, $arrS); $arrRF

To remove duplicate values from an array, you can use the foreach method or the array_unique method. the following code uses both methods. Copy codeThe code is as follows: $ ArrF = array (); $ ArrS = array (); $ IntTotal = 100; $ IntRand = 10; For (

In PHP I would like to introduce two more commonly used array filter function Array_filter and Array_unique, one is to filter the array null, one is to filter the array of duplicate values, we now look together. GrammarArray_filter

In the case of small $inttotal, for example, within 1000, the value of $intRand basically does not affect the results, the two execution time is similar. When the test $inttotal is greater than 10000, the efficiency of using array_unique is higher

PHP Two methods to remove duplicate values of the array, using the Foreach method and the Array_unique method respectively.Remove duplicate values from an array, you can use the Foreach method, or you can use the Array_unique method.PHP$arrF=Array();

To remove duplicate values from an array, you can use the foreach method or the array_unique method. the following code uses both methods. The code is as follows: $ ArrF = array (); $ ArrS = array (); $ IntTotal = 100; $ IntRand = 10; For ($ I = 0;

Copy codeThe Code is as follows: $ ArrF = array (); $ ArrS = array (); $ IntTotal = 100; $ IntRand = 10; For ($ I = 0; $ I { $ ArrF [] = rand (1, $ intRand ); $ ArrS [] = rand (1, $ intRand ); } $ ArrT = array_merge ($ arrF, $ arrS ); $ ArrRF =

In php, I will introduce two commonly used array filter functions, array_filter and array_unique. one is to filter array null values and the other is to filter array repeated values. let's take a look In php, I will introduce two commonly used array
