http_build_query
<?php
$data = array(‘foo‘=>‘bar‘,
‘baz‘=>‘boom‘,
‘cow‘=>‘milk‘,
‘php‘=>‘hypertext processor‘);
echo http_build_query($data);
输出：
foo=bar&baz=boom&cow=milk&php=hypertext+processor
?> <?php
$data = array(‘foo‘, ‘bar‘, ‘baz‘, ‘boom‘, ‘cow‘ =>‘milk‘,‘php‘ =>‘hypertext processor‘);
echo http_build_query($data);
输出：
0=foo&1=bar&2=baz&3=boom&cow=milk&php=hypertext+processor
echo http_build_query($data, ‘myvar_‘);
myvar_0=foo&myvar_1=bar&myvar_2=baz&myvar_3=boom&cow=milk&php=hypertext+processor
?> <?php
$data = array(‘user‘=>array(‘name‘=>‘Bob Smith‘,
‘age‘=>47,
‘sex‘=>‘M‘,
‘dob‘=>‘5/12/1956‘),
‘pastimes‘=>array(‘golf‘,‘opera‘,
‘poker‘,
‘rap‘),
‘children‘=>array(‘bobby‘=>array(‘age‘=>12,
‘sex‘=>‘M‘),
‘sally‘=>array(‘age‘=>8,
‘sex‘=>‘F‘)),
‘CEO‘);
echo http_build_query($data, ‘flags_‘);
输出：（为了可读性对其进行了折行）
user[name]=Bob+Smith&user[age]=47&user[sex]=M&user[dob]=5%1F12%1F1956&
pastimes[0]=golf&pastimes[1]=opera&pastimes[2]=poker&pastimes[3]=rap&
children[bobby][age]=12&children[bobby][sex]=M&children[sally][age]=8&
children[sally][sex]=F&flags_0=CEO
注意：只有基础数组中的数字下标元素“CEO”才获取了前缀，其它数字下标元素（如
pastimes 下的元素）则不需要为了合法的变量名而加上前缀。
