Php aggregates two ordered arrays

Php merges two ordered arrays. for two ordered arrays, each array is cyclically arranged to the new array. The idea is incremental, compared, and inserted in order. php code: & lt ;? Php $ arr1array (,); sample data $ arr2array (,); echo & lt; pre & gt ;; print_r (mergeOr php combines two ordered arrays

For two ordered arrays, each array is cyclically arranged to the new array;

Increment by idea, compare, and insert in sequence. php code:

 '; Print_r (mergeOrderly ($ arr1, $ arr2); // example function mergeOrderly ($ arr1, $ arr2) {if (! Count ($ arr1) {// determines whether the parameter makes sense return false;} elseif (! Count ($ arr2) {return false;} else {// merge $ arr = array (); // define the final array container $ arr2Num = count ($ arr2 ); // count the length of the array $ arr1Num = count ($ arr1); $ i1 = 0; // The Loop mark of array 1 $ i2 = 0; // while ($ i1 <$ arr1Num | $ i2 <$ arr2Num) {// whether to merge if ($ i1 <$ arr1Num & $ i2 <$ arr2Num) {// when neither of the arrays has reached the end, scenario 1: if ($ arr1 [$ i1]> $ arr2 [$ i2]) {// you need to compare array 1 and array 2. small values are placed in the target array, and Mark + 1 $ arr [] = $ arr2 [$ i2]; $ i2 ++;} else {$ arr [] = $ arr1 [$ i1]; $ i1 ++ ;}} elseif ($ i1 <$ arr1Num & $ I2 >=$ arr2Num) {// array 2 has reached the end, while array 1 is still arriving. case 2 $ arr [] = $ arr1 [$ i1]; // insert the content of array 1 directly into the target array $ i1 ++;} elseif ($ i2 <$ arr2Num & $ i1 >=$ arr1Num) {// array 1 has reached the end, while array 2 has not yet arrived. case 3 $ arr [] = $ arr2 [$ i2]; // insert the content of array 2 directly into the target array $ i2 ++ ;}}return $ arr ;}}?>
