Associative array will have their index as string so that you can establish a strong association between key and values. The associative arrays have names keys that is assigned to them.
Let us see an example−
$arr = array( "p"=>"150", "q"=>"100", "r"=>"120", "s"=>"110", "t"=>"115");
Above, we can see key and value pairs in the array.
To implement Associative Arrays in PHP, the code is as follows −
Example
<?php $arr = array( "p"=>"150", "q"=>"100", "r"=>"120", "s"=>"110", "t"=>"115", "u"=>"103", "v"=>"105", "w"=>"125" ); echo "Value 1 = " .reset($arr); ?>
Output
This will produce the following output−
Value 1 = 150
Example
Let us now see another example −
<?php $salaries = array("jack" => 2000, "qadir" => 1000); echo "Salary of jack is ". $salaries['jack'] . "\n"; $salaries['jack'] = "high"; $salaries['tom'] = "low"; echo "Salary of jack is ". $salaries['jack'] . "\n"; ?>
Output
This will produce the following output−
Salary of jack is 2000 Salary of jack is high
