I try to read in a bash script from a text file and print it to the screen via php.
I tried
$code = #file_get_contents( $myFileName );
as well as
$code = "";
$myFile = fopen($myFileName, "r");
while ($line = fgets($myFile)) {
$code .= $line;
}
However, the string I get from reading in the file doesn't contain all of the file's contents. The problem is that the text file contains the string
<<EOF
After that the String abruptly stops.
How come? It seems weird to me that php isn't able to deal with those few characters and misinterpret them as the actual EOF.
Is there a way I can read in the whole file?
Thanks in advance!
When I try it, I don't experience that problem therefore, presumably, you are outputting the text to an HTML document and testing your code by looking at the rendering of that document in a browser (as opposed to looking at the raw output of the script, as would appear in View > Source).
In HTML < indicates the start of a tag. You need to escape your HTML with htmlspecialchars() for < to be treated as data instead of markup.

I'm working with a php array which contains some values parsed from a previous scraping process (using Simple HTML DOM Parser). I can normally print / echo the values of this array, which contains special chars é,à,è, etc. BUT, the problem is the following :
When I'm using fwrite to save values in a .csv file, some characters are not successfully saved. For example, Székesfehérvár is well displayed on my php view in HTML, but saved as Székesfehérvár in the .csv file which I generate with the php script above.
I've already set-up several things in the php script :
The page I'm scraping seems to be utf-8 encoded
My PHP script is also declared as utf-8 in the header
I've tried a lot of iconv and mb_encode methods in different places in the code
NOTE that when I'm make a JS console.log of my php array, using json_encode, the characters are also broken, maybe linked to the original encoding of the page I'm scraping?
Here's a part of the script, it is the part who is writing values in a .csv file
<?php
$data = array(
array("item1", "item2"),
array("item1", "item2"),
array("item1", "item2"),
array("item1", "item2")
// ...
);
//filename
$filename = 'myFileName.csv';
foreach($data as $line) {
$string_txt = ""; //declares the content of the .csv as a string
foreach($line as $item) {
//writes a new line of the .csv
$line_txt = "";
//each line of the .csv equals to the values of the php subarray, tab separated
$line_txt .= $item . "\t";
}
//PHP endline constant, indicates the next line of the .csv
$line_txt .= PHP_EOL;
//add the line to the string which is the global content of the .csv
$line_txt .= $string_txt;
}
//writing the string in a .csv file
$file = fopen($filename, 'w+');
fwrite($file, $string_txt);
fclose($file);
I am currently stuck because I can't save values with accentuated characters correctly.
Put this line in your code
header('Content-Type: text/html; charset=UTF-8');
Hope this helps you!
Try it
$file = fopen('myFileName.csv','w');
$data= array_map("utf8_decode", $data);
fputcsv($file,$data);
Excel has problems displaying utf8 encoded csv files. I saw this before. But you can try utf8 BOM. I tried it and works for me. This is simply adding these bytes at the start of your utf8 string:
$line_txt .= chr(239) . chr(187) . chr(191) . $item . "\t";
For more info:
Encoding a string as UTF-8 with BOM in PHP
Alternatively, you can use the file import feature in Excel and make sure the file origin says 65001 : Unicode(UTF8). It should display your text properly and you will need to save it as an Excel file to preserve the format.
The solution (provided by #misorude) :
When scraping HTML contents from webpages, there is a difference between what's displayed in your debug and what's really scraped in the script. I had to use html_entity_decode to let PHP interpret the true value of the HTML code I've scraped, and not the browser's interpretation.
To validate a good retriving of values before store them somewhere, you could try a console.log in JS to see if values are correctly drived :
PHP
//decoding numeric HTML entities who represents "Sóstói Stadion"
$b = html_entity_decode("Sóstói Stadion");
Javascript (to test):
<script>
var b = <?php echo json_encode($b) ;?>;
//print "Sóstói Stadion" correctly
console.log(b);
</script>
I am trying to get PHP to search a text file for a string. I know the string exists in the text, PHP can display all the text, and yet strpos returns false.
Here is my code:
<?php
$pyscript = "testscript.py";
//$path = "C:\\Users\\eneidhart\\Documents\\Python Scripts\\";
$process_path = "C:\\Users\\eneidhart\\Documents\\ProcessList.txt";
//$processcmd = "WMIC /OUTPUT: $process PROCESS get Caption,Commandline,Processid";
$process_file = fopen($process_path, "r") or die("Unable to open file!");
$processes = fread($process_file);
if (strpos($processes, $pyscript) !== FALSE) {
echo "$pyscript found";
} elseif (strpos($processes, $pyscript) === FALSE) {
echo "$pyscript NOT found :(";
} else {
echo "UHHHHHHHH...";
}
echo "<br />";
while (!feof($process_file)) {
echo fgets($process_file)."<br />";
}
fclose($processfile);
echo "End";
?>
The while loop will print out every line of the text file, including
python.exe python testscript.py
but strpos still can't seem to find "testscript.py" anywhere in it.
The final goal of this script is not necessarily to read that text file, but to check whether or not a particular python script is currently running. (I'm working on Windows 7, by the way.) The text file was generated using the commented out $processcmd and I've tried having PHP return the output of that command like this:
$result = `$processcmd`;
but no value was returned. Something about the format of this output seems to be disagreeing with PHP, which would explain why strpos isn't working, but this is the only command I know of that will show me which python script is running, rather than just showing me that python.exe is running. Is there a way to get this text readable, or even just a different way of getting PHP to recognize that a python script is running?
Thanks in advance!
EDIT:
I think I found the source of the problem. I created my own text file (test.txt) which only contained the string I was searching for, and used file_get_contents as was suggested, and that worked, though it did not work for the original text file. Turns out that the command listed under $processcmd creates a text file with Unicode encoding, not ANSI (which my test.txt was encoded in). Is it possible for that command to create a text file with a different encoding, or even simpler, tell PHP to use Unicode, not ANSI?
You can use the functions preg_grep() and file():
$process_path = "C:\\Users\\eneidhart\\Documents\\ProcessList.txt";
$results = preg_grep('/\btestscript.py\b/', file($process_path));
if(count($results)) {
echo "string was found";
}
You should follow the advice given in the first comment and use either:
file_get_contents($process_path);
or
fread($process_file, filesize($process_path));
If that fix is not enough and there is actually a problem on strpos (which shouldn't be the case), you can use:
preg_match("/.*testscript\.py.*/", $processes)
NB: Really try to use strpos and not preg_match as it's not advised by the documentation.
Well, I found the answer. Thanks to those of you who suggested using file_get_contents(), as I would not have gotten here without that advice. Turns out that WMIC outputs Unicode, and PHP did not like reading that. The solution was another command which converts Unicode to ANSI:
cmd.exe /a /c TYPE unicode_file.txt > ansi_file.txt
I hope this helps, for those of you out there trying to check if a particular python script is working, or if you're just trying to work with WMIC.
I am using urldecode data for writing a content in to a text file, but in that file all the contents are showing together(not aligned expected) in windows notepad(in windows wordpad it is coming correctly), also when i open it in Ubuntu contents are coming correctly(my contents have enter key and spaces some special characters too).
$attachment_file = fopen(Yii::app()->basePath.'/../uploads/attachment'.$user_id.'.txt', "a+") or die("Unable to open file!");
$content = urldecode($note_data["note_data"]);
fwrite($attachment_file,$content);
fclose($attachment_file);
For the quick fix i did
$content = str_replace("\n","\r\n",$content);
but i want to know is there any other methods to do it.
If you are using Linux to create the file, you should manually add this. If you use Windows, You can try str_replace("\n", PHP_EOL, $content) instead.
I don't understand why you are doing urldecode. Maybe you should use something like utf8_decode if you have your data in utf-8 format.
Due to reasons that are have nothing to do with the actual question, I need to call and use an external script via PHP to perform a string replacement on a complete html document. The replacement strings and the source code need to be passded to this script via php exec(). For this example, I have used a simple python script to take over the replacement.
PHP script looks like this:
$source = file_get_contents("somehtmlfile.html");
$replaceString = "Some text in the HTML doc";
$replaceTo = "Some other text";
$parsedString = system("python replace.py $replaceString $replaceTo $source", $retval);
print ("Done:" .$mystring);
Then the Python script will do the following:
import sys
import string
dataFrom = sys.argv[1];
dataTo = sys.argv[2];
dataSourceCode = sys.argv[3];
rep = dataSourceCode.replace(dataFrom, dataTo);
print rep;
The problem is that I can't pass the complete html source as an argument to the shell, at least not in the way shown above. From what I understood, while the html code gets passed to the shell it interpretes some sections as commands (multiline could be an issue here I suppose).
The output I receive from the script :
sh: cannot open !DOCTYPE: No such file
sh: cannot open html: No such file
sh: cannot open head: No such file
sh: cannot open title: No such file
... (this goes on)
Any suggestions?
It is not working because there are spaces and quotes in the html text that you pass as an argument, so it is seen as multiple arguments. To solve this, you have to put quotes around the arguments.
The correct code is $parsedString = system("python replace.py '$replaceString' '$replaceTo' '$source'", $retval);
I have the following scenarion.
Everytime my page loads I create a file. Now my file has two tags within. {theme}{/theme} and {layout}{/layout}, now everytime I choose a certain layout or theme it should replace the tags with {layout}layout{/layout} and {theme}theme{/theme}
My issue is that after I run the following code
if(!file_exists($_SESSION['file'])){
$fh = fopen($_SESSION['file'],"w");
fwrite($fh,"{theme}{/theme}\n");
fwrite($fh,"{layout}{/layout}");
fclose($fh);
}
$handle = fopen($_SESSION['file'],'r+');
if ($_REQUEST[theme]) {
$theme = ($_REQUEST[theme]);
//Replacing the theme bracket in the cache file for rememberence
while($line=fgets($handle)){
$line = preg_replace("/{theme}.*{\/theme}/","{theme}".$theme."{/theme}",$line);
fwrite($handle, $line);
}
}
My output looks as follows
{theme}{/theme}
{theme}green{/theme}
And it needs to look like this
{theme}green{/theme}
{layout}layout1{/layout}
I rarely use random-access file operation but like to read it all as text and write ti back so I might be wrong here. BUT as I can see, you read the first line (so the pointer is at the beginning of the second line). Then you write '{theme}green{/theme}' into that file so it replaces the next position text (the second line).
In this case (as your data is small), you better get the hold file. Change it as string and write it back.
