如何将php的源码ifelse逻辑变成goto逻辑?
例如下面的代码
<?php
exampleFunction(1,2);
function exampleFunction(\$x, \$y) {
\$sum = \$x + \$y;
if (\$sum > 10) {
echo "Sum is greater than 10.";
} else {
echo "Sum is 10 or less.";
}
}转换成<?php
exampleFunction(1,2);
function exampleFunction($x, $y) {
$sum = $x + $y;
if ($sum > 10) goto label1;
else goto label2;
label1: echo "Sum is greater than 10.";
goto end;
label2: echo "Sum is 10 or less.";
end:

<?php
function convertToGoto($phpCode) {
$lines = explode("\n", $phpCode);
$result = [];
$gotoLabels = [];
$labelCounter = 1;
$inFunction = false;
foreach ($lines as $line) {
$trimmedLine = trim($line);
// 处理函数声明
if (preg_match('/^function\s+\w+\s*\(.*\)\s*\{/', $trimmedLine)) {
$inFunction = true;
$result[] = $line;
continue;
}
//处理函数体
if ($inFunction) {
// 递增函数体括号计数
if (strpos($trimmedLine, '{') !== false) {
$result[] = $line;
continue;
}
if (strpos($trimmedLine, '}') !== false) {
$result[] = $line;
$inFunction = false;
// 插入所有标签
