I want to make an explode as follows:
$variavel = $_GET["url"];
$var1 = explode('<div id="$variavel">',$string);
$var2 = explode('</div>',$var1[1]);
$resultado = $var2[0];
but it is giving error when trying to put the $ variable inside the () of the explode! Can someone help me!
You can use double quotes even without having to concatenate. For when using double quotes inside another it is necessary to put \ before the character "to force the IDE to understand. In your case it looks like this:
With simple quotes you would have to concatenate: < $var1 = explode("<div id=\"$variavel\">",$string);
I solved the problem !! Solution:
id="'.$_GET["url"].'"
$string='<div id="url">mamae</div>';
$variavel = "url";
$var1 = explode('<div id="'.$variavel.'">',$string);
$var2 = explode('</div>',$var1[1]);
$resultado = $var2[0];
echo $resultado;
See the difference
$variavel = "url";
$var1 = '<div id="$variavel">';
echo $var1; // vai imprimir <div id="$variavel">
result applying this way
