无法将php变量作为参数传递给javascript函数[关闭]

Question

The case is that I have a .php file and inside it, I have a function inside script tags. After it, I have php code, that reads from a file. I want to sent the file data to the js function. I had done this before, but now it will produce parsing errors.

SOLUTION

THE file format must not have line breaks!!!!
echo '<script>updateMatch1("'.$filetext.'") </script>';

Here is the code

<script>
    function updateMatch1(names) {
    alert(names);
};
</script>
<?php
    /* Read file */
    ...
    $filetext = fread( $file, $filesize ); //checked the output, it's ok

    // numerous ways I tried. Some produce an error and the page isn't loaded at all,
        // while others produce an error in the console
    echo "<script>updateMatch1('" . $filetext . "');</script>";
    //echo '<script> updateMatch1($filetext);</script>';
    //echo '<script>updateMatch1();</script>';
    //echo "<script>updateMatch1($filetext" . ")</script>";
    //echo "<script>updateMatch1($filetext)</script>";
        //echo '<script>updateMatch1(' . $filetext  . ');</script>';
?>

Check your file.txt. Maybe it contains some illegal character or has some incompatible file encoding that produce the illegal character. If you print the value of $filetext with php, there is no visible error, but it can produce some in JS. E.g. it can be the zero-width space. See if you have spaces or other characters on the end of the file.
