As a little refresher, you may have seen some query URL that looks like this:
roll_no=2&year=2nd&gpa=8.3
If you have such a URL saved in a variable, you may need to extract the variables and save them separately or as a key-value pair.
parse_str() functionThe parse_str() function is a built-in function in PHP that parses a query string into variables. This function takes URL-like strings and parses them into a variable that can be used in further manipulations.
parse_str($aString, $AnArray)
The first parameter passed is the string that is in a query format. This query string will ultimately be parsed into a variable.
The second parameter is optional. It is an array into which the result of the parser function can be stored in a key-value pair.
No value is returned by the function.
<?php// no parsing into arrayparse_str("sports=soccer&players=22");echo $sports."\n".$players;?>
<?php// Now we save the result in an arrayparse_str("fruit=apple&nutrient=30&preference=10.3", $resultArray);//display the array contentprint_r($resultArray);?>
From the two code snippets, we can see how these strings are made to become real variables and these variables are saved in the second snippet in an array.
