Both get the union of arrays, but array_merge() overwrites duplicate non_numeric keys. Let us now see an example of the array+array−Example Live DemoOutputThis will produce the following output−array(8) {    ["p"]=>    string(3) "150"    ["q"]=>    string(3) "100"    ["r"]=>    string(3) "120"    ["s"]=>    string(3) "110"    ["t"]=>    string(3) "115"    ["u"]=>    string(3) "103"    ["v"]=>    string(3) "105"    ["w"]=>    string(3) "125" }ExampleLet us now see an example of array_merge() in PHP− Live DemoOutputThis will produce the following output−array(8) {    ["p"]=>    string(3) "150"    ["q"]=>    string(3) "100"    ["r"]=>    string(3) "120"    ["s"]=>    string(3) "110"    ["t"]=>    string(3) "115"    ["u"]=>    string(3) "110"    ["v"]=>    string(3) "105"    ["w"]=>    string(3) "100" }

The print and echo are both language constructs to display strings. The echo has a void return type, whereas print has a return value of 1 so it can be used in expressions. The print_r is used to display human-readable information about a variable.ExampleLet us now see an example that displays output using echo, print, and print_r: Live DemoOutputThis will produce the following output−Array... Value = John Value = Jacob Value = Tom Value = Tim Displaying Array Values using print... Value = John Value = Jacob Value = Tom Value = Tim Displaying Array Values using print_r... Array (    [0] => John    [1] => Jacob    [2] => Tom    [3] => Tim )

To return all dates between two dates, the code is as follows −Example Live DemoOutputThis will produce the following output−array(11) {    [0]=>    string(10) "10-11-2019"    [1]=>    string(10) "11-11-2019"    [2]=>    string(10) "12-11-2019"    [3]=>    string(10) "13-11-2019"    [4]=>    string(10) "14-11-2019"    [5]=>    string(10) "15-11-2019"    [6]=>    string(10) "16-11-2019"    [7]=>    string(10) "17-11-2019"    [8]=>    string(10) "18-11-2019"    [9]=>    string(10) "19-11-2019"    [10]=>    string(10) "20-11-2019" }

To reset keys of array elements using PHP, the code is as follows−Example Live DemoOutputThis will produce the following output−array(4) {    ["p"]=>    string(3) "150"    ["q"]=>    string(3) "100"    ["r"]=>    string(3) "120"    ["s"]=>    string(3) "110" } array(4) {    [0]=>    string(3) "150"    [1]=>    string(3) "100"    [2]=>    string(3) "120"    [3]=>    string(3) "110" }ExampleLet us now see another example − Live DemoOutputThis will produce the following output−array(4) {    [8]=>    string(3) "Ben"    [4]=>    string(5) "Kevin"    [7]=>    string(4) "Mark"    [3]=>    string(5) "Hanks" } array(4) {    [0]=>    string(3) "Ben"    [1]=>    string(5) "Kevin"    [2]=>    string(4) "Mark"    [3]=>    string(5) "Hanks" }

To remove the first character of a string in PHP, the code is as follows−Example Live DemoOutputThis will produce the following output −Before removing the first character = Test After removing the first character = estExampleLet us now see another example Live DemoOutputThis will produce the following output−Before removing the first character = Demo After removing the first character = emo

To remove an array element and re-index the array, the code is as follows−Example Live DemoOutputThis will produce the following output−Array with leading and trailing whitespaces... Value = John Value = Jacob Value = Tom Value = Tim Comma separated list... John , Jacob , Tom , Tim Updated Array... Value = John Value = Jacob Value = Tom Value = Tim Updated Array...Re-indexed Value = John Value = Tom Value = Tim
