How would you write a sorting routine in PHP that would replace the values of an array's keys, with another array's key value's if the former array's key value's are out of order.
$array1 = ['section2', 'section3', 'section1'];
$array2 = ['content for section1', 'content for section2', 'content section3'];
How could I replace the values of $array1 with the corrosponding content in $array2?
So I guess what I'm asking is how can I make $array1 display the following....
content for section2
content for section3
content for section1
in that order.
Loop both arrays and check if the value of $array1 exists while looping $array2, if so, change the value of $array1 to the $array2 value based on the key, so you can keep the order, i.e.:
$array1 = ['section2', 'section3', 'section1'];
$array2 = ['content for section1', 'content for section2', 'content for section3'];
foreach($array1 as $key => $value){
foreach($array2 as $key2 => $value2){
if(preg_match("/$value/", $value2)){
$array1[$key] = $value2;
}
}
}
print_r($array1);
Output:
Array
(
[0] => content for section2
[1] => content for section3
[2] => content for section1
)
