array_replace() function replace the value of from array between
<?php
$pro=array("programming"=>"java","script"=>"javascript");
$taste=array("dcode"=>"php","programming"=>"tough",);
print_r(array_replace($pro,$taste));
?>
result will be Array ( [programming] => tough [script] => javascript [dcode] => php )
it means array_replace() function rewrite array with first to last , common key name will overwritten and other get merged
<?php
$pro=array("programming"=>"java","script"=>"javascript");
$taste=array("dcode"=>"php","allcode"=>"tough",);
print_r(array_replace($pro,$taste));
?>
suppose in above code there is no common key between so it gets merged two array
so result will be Array ( [programming] => java [script] => javascript [dcode] => php [allcode] => tough )
lets see how array_replace() function with multidimensional array
<?php
$pro=array("programming"=>"java","script"=>"javascript");
$taste=array("dcode"=>"php","allcode"=>"tough",);
$tested=array("0"=>array("php","dcode"=>"java"),
"dcode"=>array("php"),
"allcode"=>"asdf",);
print_r(array_replace($pro,$taste,$tested));
?>
the common key between the arrays than last array value will be returned and the other remains untouched.
Array ( [programming] => java [script] => javascript [dcode] => Array ( [0] => php ) [allcode] => asdf [0] => Array ( [0] => php [dcode] => java ) )
