PHP与命令行交互（实现查找和替换）

// Ask for Input
fwrite(STDOUT, "Please Select Option(Default is Find) [1]Find [2]Replace Please Input Number: ");

// Get Input
$todo = trim(fgets(STDIN));
if(empty($todo)) $todo =1;
if($todo != 1 && $todo !=2){
echo "Selected Error! ";
exit;
}
if($todo==1){
fwrite(STDOUT,"Please Input Find Directory(Default is Current Directory):");
$dir = trim(fgets(STDIN));
if(empty($dir)){
$dir = getcwd();//当前目录
}else{
if(!is_dir($dir)){
echo "Directory Not Exist! ";
exit;
}
}
fwrite(STDOUT,"Please Input Content of the Find:");
$search = trim(fgets(STDIN));
echo "In Directory'".$dir."'Find'".$search."',Please Wait... ";
exec("find ".$dir." -exec grep --exclude='*.svn/*' -- '".$search."' {} +",$output);
foreach($output as $val){
echo "$val ";
}
}else{// write input back
fwrite(STDOUT, "Please Input Find Directory(Default is Current Directory):");
$dir = trim(fgets(STDIN));
if(empty($dir)){
$dir = getcwd();//当前目录
}else{
if(!is_dir($dir)){

}
fwrite(STDOUT,"Please Input Prefix(Default is php):");

if(empty($ext)) $ext = 'php';
fwrite(STDOUT,"Please Input Find Content:");
$search = trim(fgets(STDIN));
fwrite(STDOUT,"Please Input Replace Content:");
