How to Convert Text to Speech in PHP - php

How can I convert text to speech using PHP, possibly generating an MP3 file and sending that back to the user?
Thank You.

Probably following is the code as mentioned in the above link:
<?php
//create a random number filename so that simultaneous users don't overwrite each other
$filename = 'test.txt';
$text = 'This text will be converted to audio recording';
$outputfile = basename($filename, ".txt");
$outputfile = $outputfile . '.wav';
if (!$handle = fopen($filename, "w"))
{
//we cannot open the file handle!
return false;
}
// Write $text to our opened file.
if (fwrite($handle, $text) === FALSE)
{
//couldn't write the file...Check permissions
return false;
}
fclose($handle);
//initialise and execute the festival C engine
//make sure that your environment is set to find the festival binaries!
$cmd = "text2wave $filename -o $outputfile";
//execute the command
exec($cmd);
unlink($filename);
echo "Recording is successful. \nRecording File: " . $outputfile;
//finally return the uptput file path and filename
return $outputfile;
?>

if you use macos you can simply use apple tts
shell_exec("say -o test.aiff this is a test");

PHP. How to read a file, if it is writing without a problem with "a+", but is not readable with "r"?

I have two scripts: one of them writes the value of a variable to a file. In another script, I try to read it. It is written without problems, but it is not readable.
Here I write to a file:
$peer_id=2000000001;
$fileLocation = getenv("DOCUMENT_ROOT") . "/peer_id.txt";
$file = fopen($fileLocation,"a+");
fwrite($file, $peer_id);
fclose($file);
Here I read the file:
$fileLocation = getenv("DOCUMENT_ROOT") . "/peer_id.txt";
$file = fopen($fileLocation,"r");
if(file_exists($fileLocation)){
// Result is TRUE
}
if(is_readable ($file)){
// Result is FALSE
}
// an empty variables, because the file is not readable
$peer_id = fread($file);
$peer_id = fileread($file);
$peer_id = file_get_contents($file);
fclose($file);
The code runs on "sprinthost" hosting, if that makes a difference. There are suspicions that this is because of that hosting.
file_get_contents in short runs the fopen, fread, and fclose. You don't use a pointer with it. You should just use:
$peer_id = file_get_contents($fileLocation);
That is the same for is_readable:
if(is_readable($fileLocation)){
// Result is FALSE
}
So full code should be something like:
$fileLocation = getenv("DOCUMENT_ROOT") . "/peer_id.txt";
if(file_exists($fileLocation) && is_readable($fileLocation)) {
$peer_id = file_get_contents($fileLocation);
} else {
echo 'Error message about file being inaccessible here';
}
The file_get_contents has an inverse function for writing; https://www.php.net/manual/en/function.file-put-contents.php. Use that with the append constant and you should have the same functionality your first code block had:
file_put_contents($fileLocation, $peer_id, FILE_APPEND | LOCK_EX);

My php script won't open files that aren't in its root directory

This is a php script for a user login system that I am developing.
I need it to read from, and write to, the /students/students.txt file, but it won't even read the content already contained in the file.
<?php
//other code
echo "...";
setcookie("Student", $SID, time()+43200, "/");
fopen("/students/students.txt", "r");
$content = fread("/students/students.txt", filesize("/students/students.txt"));
echo $content;
fclose("/students/students.txt");
fopen("/students/students.txt", "w");
fwrite("/students/students.txt", $content."\n".$SID);
fclose("/students/students.txt");
//other code
?>
You are not using fopen() properly. The function returns a handle that you then use to read or edit the file, for example:
//reading a file
if ($handle = fopen("/students/students.txt", "r"))
{
echo "info obtained:<br>";
while (($buffer = fgets($handle))!==false)
{ echo $buffer;}
fclose($handle);
}
//writing/overwriting a file
if ($handle = fopen("/students/students.txt", "w"))
{
fwrite($handle, "hello/n");
fclose($handle);
}
Let me know if that worked for you.
P.S.: Ty to the commentators for the constructive feedback.
There are many ways to read/write to file as others have demonstrated. I just want to illustrate the mistake in your particular approach.
fread takes a file handle as param, NOT a string that represents the path to the file.
So your line:
$content = fread("/students/students.txt", filesize("/students/students.txt")); is incorrect.
It should be:
$file_handle = fopen("/students/students.txt", "r");
$content = fread($file_handle, filesize("/students/students.txt"));
Same thing when you write contents to file using fwrite. Its reference to the file is a File Handle opened using fopen NOT the filepath. when opening a file using fopen() you can also check if the $file_handle returned is a valid resource or is false. If false, it means the fopen operation was not successful.
So your code:
fopen("/students/students.txt", "w");
fwrite("/students/students.txt", $content."\n".$SID);
fclose("/students/students.txt");
Needs to be re-written as:
$file_handle = fopen("/students/students.txt", "w");
fwrite($file_handle, $content."\n".$SID);
fclose($file_handle);
You can see that fclose operates on file handles as well.
File Handle (as per php.net):
A file system pointer resource that is typically created using fopen().
Here are a couple of diagnostic functions that allow you to validate that a file exists and is readable. If it is a permission issue, it gives you the name of the user that needs permission.
function PrintMessage($text, $success = true)
{
print "$text";
if ($success)
print " [<font color=\"green\">Success</font>]<br />\n";
else
print(" [<font color=\"red\">Failure</font>]<br />\n");
}
function CheckReadable($filename)
{
if (realpath($filename) != "")
$filename = realpath($filename);
if (!file_exists($filename))
{
PrintMessage("'$filename' is missing or inaccessible by '" . get_current_user() . "'", false);
return false;
}
elseif (!is_readable($filename))
{
PrintMessage("'$filename' found but is not readable by '" . get_current_user() . "'", false);
return false;
}
else
PrintMessage("'$filename' found and is readable by '" . get_current_user() . "'", true);
return true;
}
I've re-written your code with (IMO) a cleaner and more efficient code:
<?php
$SID = "SOMETHING MYSTERIOUS";
setcookie("Student", $SID, time()+43200, "/");
$file = "/students/students.txt"; //is the full path correct?
$content = file_get_contents($file); //$content now contains /students/students.txt
$size = filesize($file); //do you still need this ?
echo $content;
file_put_contents($file, "\n".$SID, FILE_APPEND); //do you have write permissions ?
file_get_contents
file_get_contents() is the preferred way to read the contents of a
file into a string. It will use memory mapping techniques if supported
by your OS to enhance performance.
file_put_contents
This function is identical to calling fopen(), fwrite() and
fclose() successively to write data to a file. If filename does not
exist, the file is created. Otherwise, the existing file is
overwritten, unless the FILE_APPEND flag is set.
Notes:
Make sure the full path /students/students.txt is
correct.
Check if you've read/write permissions on /students/students.txt
Learn more about linux file/folder permissions or, if you don't access to the shell, how to change file or directory permissions via ftp
Try to do this:
fopen("students/students.txt", "r");
And check to permissions read the file.

Read .txt with php and write to the same file

I'm working on what seems to be a simple php reading and writing to a txt file. I'm able to read the file but not write. I've tried variations of the following but to no avail. I'm trying to read the txt file that will have a 0 or a 1 in it and switch it. But for some reason I can only read. How can I make this code write to the file? Note I do have write permissions to the txt file.
Thx
Rich
<?php
$status = readfile("0.txt");
echo $status;
$file_handle = fopen("../light_switches/0.txt", "w");
if($status = 1){
$file_contents = "0";
fwrite($file_handle, $file_contents);
}
else if($status = 0){
$file_contents = "1";
fwrite($file_handle, $file_contents);
}
fclose($file_handle);
?>
readfile returns the number of bytes read from the file, but not the file content.
You could use file_get_contents to get the file content, and use file_put_contents to write:
$path = "../light_switches/0.txt";
file_put_contents($path, file_get_contents($path) === '0' ? '1' : '0');
Use file_put_contents(). It is the same as calling fopen(), fwrite(), and fclose(). Use the flag FILE_APPEND
file_put_contents($filepath, $content, FILE_APPEND);
PHP Documentation
EDIT
I have reworked this code. If all you are doing is trying to switch the 0 and 1 of the txt file, this code is working. Simply just replace the file path with yours.
<?php
$file_path = '0.txt';
if (!file_exists($file_path)) {
echo 'File does not exist';
exit;
}
$currentContent = file_get_contents($file_path);
echo $currentContent;
if ($currentContent == '0') {
$newContent = '1';
}
elseif ($currentContent == '1') {
$newContent = '0';
}
else {
//Start the file fresh if it found extra lines for example
$newContent = '0';
}
file_put_contents($file_path, $newContent);
?>

PHP not writing to file from one source

I have an issue I can't seem to find the solution for. I am trying to write to a flat text file. I have echoed all variables out on the screen, verified permissions for the user (www-data) and just for grins set everything in the whole folder to 777 - all to no avail. Worst part is I can call on the same function from another file and it writes. I can't see to find the common thread here.....
function ReplaceAreaInFile($AreaStart, $AreaEnd, $File, $ReplaceWith){
$FileContents = GetFileAsString($File);
$Section = GetAreaFromFile($AreaStart, $AreaEnd, $FileContents, TRUE);
if(isset($Section)){
$SectionTop = $AreaStart."\n";
$SectionTop .= $ReplaceWith;
$NewContents = str_replace($Section, $SectionTop, $FileContents);
if (!$Handle = fopen($File, 'w')) {
return "Cannot open file ($File)";
exit;
}/*
if(!flock($Handle, LOCK_EX | LOCK_NB)) {
echo 'Unable to obtain file lock';
exit(-1);
}*/
if (fwrite($Handle, $NewContents) === FALSE) {
return "Cannot write to file ($File)";
exit;
}else{
return $NewContents;
}
}else{
return "<p align=\"center\">There was an issue saving your settings. Please try again. If the issue persists contact your provider.</p>";
}
}
Try with...
$Handle = fopen($File, 'w');
if ($Handle === false) {
die("Cannot open file ($File)");
}
$written = fwrite($Handle, $NewContents);
if ($written === false) {
die("Invalid arguments - could not write to file ($File)");
}
if ((strlen($NewContents) > 0) && ($written < strlen($NewContents))) {
die("There was a problem writing to $File - $written chars written");
}
fclose($Handle);
echo "Wrote $written bytes to $File\n"; // or log to a file
return $NewContents;
and also check for any problems in the error log. There should be something, assuming you've enabled error logging.
You need to check for number of characters written since in PHP fwrite behaves like this:
After having problems with fwrite() returning 0 in cases where one
would fully expect a return value of false, I took a look at the
source code for php's fwrite() itself. The function will only return
false if you pass in invalid arguments. Any other error, just as a
broken pipe or closed connection, will result in a return value of
less than strlen($string), in most cases 0.
Also, note that you might be writing to a file, but to a different file that you're expecting to write. Absolute paths might help with tracking this.
The final solution I ended up using for this:
function ReplaceAreaInFile($AreaStart, $AreaEnd, $File, $ReplaceWith){
$FileContents = GetFileAsString($File);
$Section = GetAreaFromFile($AreaStart, $AreaEnd, $FileContents, TRUE);
if(isset($Section)){
$SectionTop = $AreaStart."\n";
$SectionTop .= $ReplaceWith;
$NewContents = str_replace($Section, $SectionTop, $FileContents);
return $NewContents;
}else{
return "<p align=\"center\">There was an issue saving your settings.</p>";
}
}
function WriteNewConfigToFile($File2WriteName, $ContentsForFile){
file_put_contents($File2WriteName, $ContentsForFile, LOCK_EX);
}
I did end up using absolute file paths and had to check the permissions on the files. I had to make sure the www-data user in Apache was able to write to the files and was also the user running the script.

Unpack large files with gzip in PHP

I'm using a simple unzip function (as seen below) for my files so I don't have to unzip files manually before they are processed further.
function uncompress($srcName, $dstName) {
$string = implode("", gzfile($srcName));
$fp = fopen($dstName, "w");
fwrite($fp, $string, strlen($string));
fclose($fp);
}
The problem is that if the gzip file is large (e.g. 50mb) the unzipping takes a large amount of ram to process.
The question: can I parse a gzipped file in chunks and still get the correct result? Or is there a better other way to handle the issue of extracting large gzip files (even if it takes a few seconds more)?
gzfile() is a convenience method that calls gzopen, gzread, and gzclose.
So, yes, you can manually do the gzopen and gzread the file in chunks.
This will uncompress the file in 4kB chunks:
function uncompress($srcName, $dstName) {
$sfp = gzopen($srcName, "rb");
$fp = fopen($dstName, "w");
while (!gzeof($sfp)) {
$string = gzread($sfp, 4096);
fwrite($fp, $string, strlen($string));
}
gzclose($sfp);
fclose($fp);
}
try with
function uncompress($srcName, $dstName) {
$fp = fopen($dstName, "w");
fwrite($fp, implode("", gzfile($srcName)));
fclose($fp);
}
$length parameter is optional.
If you are on a Linux host, have the required privilegies to run commands, and the gzip command is installed, you could try calling it with something like shell_exec
SOmething a bit like this, I guess, would do :
shell_exec('gzip -d your_file.gz');
This way, the file wouldn't be unzip by PHP.
As a sidenote :
Take care where the command is run from (ot use a swith to tell "decompress to that directory")
You might want to take a look at escapeshellarg too ;-)
As maliayas mentioned, it may lead to a bug. I experienced an unexpected fall out of the while loop, but the gz file has been decompressed successfully. The whole code looks like this and works better for me:
function gzDecompressFile($srcName, $dstName) {
$error = false;
if( $file = gzopen($srcName, 'rb') ) { // open gz file
$out_file = fopen($dstName, 'wb'); // open destination file
while (($string = gzread($file, 4096)) != '') { // read 4kb at a time
if( !fwrite($out_file, $string) ) { // check if writing was successful
$error = true;
}
}
// close files
fclose($out_file);
gzclose($file);
} else {
$error = true;
}
if ($error)
return false;
else
return true;
}
