Question

i have this function that insert code in my file.php:

function InsertData($nombre, $var1, $var2, $var3)
{
    $file = fopen("$nombre".".php", "r+");
    // Seek to the end
    fseek($file, SEEK_END, 0);
    // Get and save that position
    $filesize = ftell($file);
    // Seek to half the length of the file
    fseek($file, SEEK_SET, $filesize / 1);
    // Write your data
    fwrite($file, "<?php
class " ."$nombre". "\n
{\n
private $" ."$var1;". "\n
private $" ."$var2;". "\n
private $" ."$var3;". "\n
\n\n
    public function __construct()\n
    {\n
        $this->setData($" ."$var1". ", $" ."$var2". ", $" ."$var3". ");\n
        //parent::__construct();\n

    }
\n\n
    public function setData($" ."$var1". ", $" ."$var2". ", $" ."$var3". ")\n
    {\n
        $this->" ."$var1". "= $" ."$var1;". "\n
        $this->" ."$var2". "= $" ."$var2;". "\n
        $this->" ."$var3". "= $" ."$var3;". "\n
    }
\n\n
    public function printData()
    {\n
        echo \"SomeThing : \" . $this->" ."var1". ". \" \" . $this->" ."var2". ".     \"\n\";\n
        echo \"Other : \" . $this->" ."var3". ". \"\n\";\n
    }
\n\n
}
\n\n
?>");
    // Close the file handler
    fclose($file);
}

but when i call it i get this error: Catchable fatal error: Object of class Creator could not be converted to string in create.php on line 37

line 37 is:

$this->" ."$var1". "= $" ."$var1;". "\n

im calling it like this in other file:

$lol = new Creator();
$lol->CreateFile($input);
$lol->InsertData($input, $input1, $input2, $input3);

How can i solve this?

Answer 1

You are using wrong quotes for the whole class you are trying to generate. Try to change double quotes " to single quotes '. The error is because when you use "$this" PHP is trying to call $this->__toString(), in this context is $this still a variable from your outside code. Using '$this' (in single quotes) is just nothing more than simple string.

Another solution whould be to add backslash before $this – "\$this"
