How to access an associative array by integer index in PHP?
To access an associative array by integer index in PHP, the code is as follows−
Example
Live Demo
<?php
$arr = array( "p"=>"150", "q"=>"100", "r"=>"120", "s"=>"110");
$keys = array_keys( $arr );
echo "Array key and value...\n";
for($x = 0; $x < sizeof($arr); $x++ ) {
echo "key: ". $keys[$x] . ", value: ". $arr[$keys[$x]] . "\n";
}
?>Output
This will produce the following output−
Array key and value...
key: p, value: 150
key: q, value: 100
key: r, value: 120
key: s, value: 110
Example
Let us now see another example−
Live Demo
<?php
$arr = array( "p"=>"150", "q"=>"100", "r"=>"120", "s"=>"110");
$keys = array_keys( $arr );
echo "Array key and value...\n";
for($x = 0; $x < sizeof($arr); $x++ ) {
echo "key: ". $keys[$x] . ", value: ". $arr[$keys[$x]] . "\n";
}
$arr[$keys[2]] = "20";
$arr[$keys[3]] = "10";
echo "\nUpdated Array key and value...\n";
for($x = 0; $x < sizeof($arr); $x++ ) {
echo "key: ". $keys[$x] . ", value: ". $arr[$keys[$x]] . "\n";
}
?>Output
This will produce the following output−
Array key and value...
key: p, value: 150
key: q, value: 100
key: r, value: 120
key: s, value: 110
Updated Array key and value...
key: p, value: 150
key: q, value: 100
key: r, value: 20
key: s, value: 10
