They could help me with a problem:
I want to execute PHP code inside Javascript .
<html>
<head></head>
<body>
<script type="text/javascript">
<?php echo "hola como estan"; ?>);
</script>
</body>
</html>
The html output:
<html>
<head></head>
<body>
<script type="text/javascript">
hola como estan <-- marcado en rojo en el inspector del navegador
</script>
</body>
</html>
The error in the browser console:
Uncaught SyntaxError: Unexpected identifier
I think there is a conceptual error when it comes to structuring the task you want to do.
Really PHP is not executed within Javascript , but Javascript will make use of what PHP prints within its labels or functions. Since PHP is a server language, it will be executed before Javascript .
Basic to be understood, the order in which they are executed:
1st PHP (server)
2nd HTML (browser)
3rd Javascript (browser)
Then the flow would go like this:
1.- What result do we want to achieve?
<html>
<head></head>
<body>
<script>
alert("hola como estan");
</script>
</body>
</html>
2.- What part of that result will you manage PHP ?
hola como estan
3.- How does PHP print this text inside html ?
<?php echo "hola como estan"; ?>
4.- How do you get everything going?
<html>
<head></head>
<body>
<script>
alert("<?php echo "hola como estan"; ?>");
// ^ ^
// (1) (2)
</script>
</body>
</html>
Beware of the syntax, the Javascript quotes must be maintained.
<?php
// varios textos en un array
$txt = array(
"Hola como estan",
"Hola que tal va",
"Hola ke ase XD",
);
// desordena el contenido del array
shuffle($txt);
?>
<html>
<head></head>
<body>
<script>
// cada vez que recarga el navegador
// debería lanzar el texto de forma
// aleatoria
alert("<?php echo $txt[0]; ?>");
</script>
</body>
</html>
Just as you have it is a syntax error. If you want to write something you can use the console like this:
<?php echo "console.log('hola como estan');"
Or an alert like that:
<?php echo "alert('hola como estan');"
