i am trying to echo below. pure text.
<script src="<?php echo $config['dir_plugins']; ?>qroll.js"></script>
but it wont echo correctly.below is code.somehow it omits the echo as aa string and with it most of the other parts of the string.
<?php
$arr = array("qroll", "validate", "hellios");
$str2 = "src='<?php echo \$config[\'dir_plugins\']; ";
foreach ($arr as &$value) {
echo $str2;
echo $value;
}
?>
it just returns src='
This line is strange:
$str2 = "src='<?php echo \$config[\'dir_plugins\']; ";
I think it should be
$str2 = "src='".$config[\'dir_plugins\']."'";
This does what I think you are asking for
<?php
$arr = array("qroll", "validate", "hellios");
$str2 = '<script src="<?php echo $config[\'dir_plugins\']; ?>"';
foreach ($arr as &$value) {
echo $str2 . $value . '.js></script>';
//echo PHP_EOL;
}
?>
OUTPUT
<script src="<?php echo $config['dir_plugins']; ?>"qroll.js></script>
<script src="<?php echo $config['dir_plugins']; ?>"validate.js></script>
<script src="<?php echo $config['dir_plugins']; ?>"hellios.js></script>
To avoid PHP evaluating a string, do not use "
but '
$str2 = 'src=\'<?php echo $config[\'dir_plugins\']; ';
should do the trick
Note that if you didnt set the page as text/plain
your browser will hide everything after the <?
because of the <
. You may want to use the <
to force it to be printed for debug purpose.
Following on from some comments, it appears that the user acutally wants to echo a string that includes some PHP in it.
If the desired output is:
src='<?php echo $config['dir_plugins']; ?>
Change your code to:
$str2 = "src='<?php echo \$config['dir_plugins']; ?>";
This will output:
src='<?php echo $config['dir_plugins']; ?>
Presumably the rest of the output (the script name and script tags) will be added by your code.
You are in effect escaping the HTML-incompatible parts of your output by converting <
to <
and >
to >
If you are trying to echo HTML code for display on your page, you can always try htmlspecialchars which will convert <
to <
and >
to >
for you.
<?php
$arr = array("qroll", "validate", "hellios");
$str2 = "src='<?php echo \$config[\'dir_plugins\']; ";
foreach ($arr as &$value) {
echo htmlspecialchars($str2);
echo $value;
}
Output in source:
src='<?php echo $config[\'dir_plugins\']; qrollsrc='<?php echo $config[\'dir_plugins\']; validatesrc='<?php echo $config[\'dir_plugins\']; hellios
Output on page:
src='<?php echo $config[\'dir_plugins\']; qrollsrc='<?php echo $config[\'dir_plugins\']; validatesrc='<?php echo $config[\'dir_plugins\']; hellios
<?php
$str2 = 'src=\'<?php echo $config[\'dir_plugins\']; ?>\'';
echo htmlspecialchars($str2);
Output on page:
src='<?php echo $config['dir_plugins']; ?>'
Here is an example of everything together:
<pre>
<?php
$arr = array('qroll', 'validate', 'hellios');
$str2 = '<script src=\'<?php echo $config[\'dir_plugins\']; ?>';
$str3 = '.js\'></script>';
foreach ($arr as $value) {
echo htmlspecialchars($str2), $value, htmlspecialchars($str3), "\n";
}
?>
</pre>
Which will look like this on your page:
<script src='<?php echo $config['dir_plugins']; ?>qroll.js'></script>
<script src='<?php echo $config['dir_plugins']; ?>validate.js'></script>
<script src='<?php echo $config['dir_plugins']; ?>hellios.js'></script>
