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
<?php $arr = array( "p"=>"150", "q"=>"100", "r"=>"120", "s"=>"110"); $keys = array_keys( $arr ); echo "Array key and value...
"; for($x = 0; $x < sizeof($arr); $x++ ) { echo "key: ". $keys[$x] . ", value: ". $arr[$keys[$x]] . "
"; } ?>
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−
<?php $arr = array( "p"=>"150", "q"=>"100", "r"=>"120", "s"=>"110"); $keys = array_keys( $arr ); echo "Array key and value...
"; for($x = 0; $x < sizeof($arr); $x++ ) { echo "key: ". $keys[$x] . ", value: ". $arr[$keys[$x]] . "
"; } $arr[$keys[2]] = "20"; $arr[$keys[3]] = "10"; echo "
Updated Array key and value...
"; for($x = 0; $x < sizeof($arr); $x++ ) { echo "key: ". $keys[$x] . ", value: ". $arr[$keys[$x]] . "
"; } ?>
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
