Merge two arrays in PHP
The array_merge() function merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.
<?php
$A1=array("apple","papaya");
$A2=array("banana","grapes");
print_r(array_merge($A1,$A2));
?>
Output would be :
Array ( [0] => apple[1] => papaya[2] => banana [3] => grapes ) Increase the PHP Script execution time
set_time_limit : set/increase the PHP Script maximum execution time
By default, PHP has a set of seconds limit to execute the script, if some script reach to run then some fatal error occurs.
