我在PHP中遇到了一些问题。
我的代码：
function fillArray($line, $col, $par0, $par1, $par2, $par3){
$arr[$line][$col][0] = $par0;
$arr[$line][$col][1] = $par1
$arr[$line][$col][2] = $par2;
$arr[$line][$col][3] = $par3;
return $arr
}
function show() {
for( $a = 0; $a < 5; $a++) {
fillArray( $a, 0, "test", "test","test", "test");
}
for($b = 0; $b < 5; $b++) {
$c = 1;
fillArray( $b, $c, "test", "test","test", "test");
$c = 2;
fillArray( $b, $c, "test", "test","test", "test");
}
return $arr;
}
我想使用$arr，但$arr感觉好像只知道一个键：
var_dump(show());
或者我有这个：注意：未定义的变量：arr？

您需要像这样
捕获输出function show(){
for( $a = 0; $a < 5; $a++ ){
$arr[] = fillArray( $a, 0, "test", "test","test", "test");
}
for( $b = 0; $b < 5; $b++){
$c = 1;
$arr[] = fillArray( $b, $c, "test", "test","test", "test");
$c = 2;
$arr[] = fillArray( $b, $c, "test", "test","test", "test");
}
return $arr;
}
还根据您的输出需求更新fillArray（）调用。使用此代码后将删除通知。

首先调用show function然后更新缺少结束';'
<?php
$result = show();
echo "<pre>";
print_r($result);
function fillArray($line, $col, $par0, $par1, $par2, $par3)
{
$arr[$line][$col][0] = $par0;
$arr[$line][$col][1] = $par1; // add ;
$arr[$line][$col][2] = $par2;
$arr[$line][$col][3] = $par3;
return $arr; // add ; for end
}
function show()
{
for ($a = 0; $a < 5; $a++) {
$arr[] = fillArray($a, 0, "test", "test", "test", "test");
}
for ($b = 0; $b < 5; $b++) {
$c = 1;
$arr[] = fillArray($b, $c, "test", "test", "test", "test");
$c = 2;
$arr[] = fillArray($b, $c, "test", "test", "test", "test");
}
return $arr;
}
然后你会看到你的输出：
