The 2nd and 3rd arguments do different things, with the 2nd one only doing anything for numerically indexed elements in the array supplied as the 1st argument (of which you have none, so it does nothing). The 3rd argument defines the separator between key/value pairs -- and if the default for your PHP configuration is to use
http_build_query() Parameter Puzzles
Hi,
I don’t understand this.
The 4 echoes, all echo the same thing.
“`
<?php
$query_string = array(
“find” => “keyword”,
“tbl” => “links”,
“col” => “keyword”,
“max” => “100”
);
echo http_build_query($query_string); echo ‘<br>’;
echo http_build_query($query_string) . “n”; echo ‘<br>’;
echo http_build_query($query_string, ‘&’); echo ‘<br>’;
echo http_build_query($query_string, ”, ‘&’); echo ‘<br>’;
?>
Q1. So, what’s the use of the latter 3 when the first echo is the simplest ?
Q2. And, what’s the use of adding the “&” on the 4th param as without it the url still contains the & as a separator separating the params ?
““
echo http_build_query($query_string, ‘&’); echo ‘<br>’;
Q3. And, why is the 3rd param here empty ?
““
echo http_build_query($query_string, ”, ‘&’); echo ‘<br>’;
