This article describes the method of combining and splitting php numbers. Share it for your reference. The details are as follows:

&lt;?php 
$array1 = array("A","B","C","D"); 
$array2 = array("1","2","3","4"); 
$array3 = array("!","@","#","$"); 
$arrayX = array_merge($array1, $array2, $array3);
//Combine 3 numbers togetherprint_r($arrayX); 
?&gt;

&lt;?php 
$array1 = array("AA"=&gt;"A","BB"=&gt;"B","CC"=&gt;"C","DD"=&gt;"D"); 
$array2 = array("AA"=&gt;"1","BB"=&gt;"2","CC"=&gt;"3","DD"=&gt;"4"); 
$array3 = array("AA"=&gt;"!","BB"=&gt;"@","CC"=&gt;"#","DD"=&gt;"$"); 
$arrayX = array_merge($array1, $array2, $array3);
//Merge arrayprint_r($arrayX); 
?&gt;

&lt;?php 
$array1 = array("AA"=&gt;"A","BB"=&gt;"B","CC"=&gt;"C","DD"=&gt;"D"); 
$array2 = array("AA"=&gt;"1","BB"=&gt;"2","CC"=&gt;"3","DD"=&gt;"4"); 
$array3 = array("AA"=&gt;"!","BB"=&gt;"@","CC"=&gt;"#","DD"=&gt;"$"); 
$arrayX = array_merge_recursive($array1, $array2, $array3);
//Merge arrayprint_r($arrayX); 
?&gt;

&lt;?php 
$array = array(1,2,3,4,5,6,7,8,9); 
$arrayX = array_splice($array, 2, 6);
//Get the second element to the 7th element of the arrayprint_r($array); 
print_r($arrayX); 
?&gt;
