PHP中多维数组的排序
1.用户定义排序：usort($array, functionName);其中functionName为用户定义的函数名，用户定义的函数指定排序规则，比较数组中两个元素的大小，大于返回正数，小于返回负数，等于返回0。2.反向用户排序：用户定义函数时，比较数组中两个元素的大小，大于返回负数，小于返回正数，等于返回0。$fruits = array(array('APP', 'Apple', 3.2), array('ORG', 'Orange', 2.6),
array('JIM','linina','3.4'));
echo 'Init:
';
foreach($fruits as $key)
{
echo $key['2'];
}
//按名称排序
function compareByName($x, $y) {
if ($x[1] == $y[1]) {
return 0;
}
else if ($x[1] > $y[1]) {
return 1;
} else {
return -1;
}
}
usort($fruits, 'compareBYName');
echo '
Compare By Name:
';
for ($i = 0; $i < 3; $i++) {
for ($j = 0; $j < 3; $j++) {
echo '|'.$fruits[$i][$j];
}
echo '
';
}
//按价格排序
function compareByPrice($x, $y) {
if ($x[2] == $y[2]) {
return 0;
}
else if ($x[2] > $y[2]) {
return 1;
}
else {
return -1;
}
}
usort($fruits, 'compareBYPrice');
echo '
Compare By Price:
';
for ($i = 0; $i < 3; $i++) {
for ($j = 0; $j < 3; $j++) {
echo '|'.$fruits[$i][$j];
}
echo '
';
}
//按价格反向排序
function reverse_compareByPrice($x, $y) {
if ($x[2] == $y[2]) {
return 0;
}
else if ($x[2] > $y[2]) {
return -1;
}
else {
return 1;
}
}
usort($fruits, 'reverse_compareByPrice');
echo '
Reverse Compare By Price:
';
for ($i = 0; $i < 3; $i++) {
for ($j = 0; $j < 3; $j++) {
echo '|'.$fruits[$i][$j];
}
echo '
';
}
