Complete PHP Misc Reference
Definition and Usage
The show_source() function outputs a file with the PHP syntax highlighted. The syntax is highlighted by using HTML tags.
The colors used for highlighting can be set in the php.ini file or with the ini_set() function.
This function returns TRUE on success, or FALSE on failure.
show_source() is an alias of highlight_file().
Syntax
show_source(filename,return)
| Parameter | Description |
|---|---|
| filename | Required. Specifies the file to display |
| return | Optional. If this parameter is set to TRUE, this function will return the highlighted code as a string, instead of printing it out. Default is FALSE |
Tips and Notes
Note: When using this function, the entire file will be displayed - including passwords and any other sensitive information!
Example
"test.php":
<html>
<body>
<?php
show_source("test.php");
?>
</body>
</html>
<body>
<?php
show_source("test.php");
?>
</body>
</html>
The output of the code above could be:
<html>
<body>
<?php show_source("test.php");?>
</body>
</html>
<body>
<?php show_source("test.php");?>
</body>
</html>
and, if you select "View source" in the browser window, it will look something like this:
<html>
<body>
<span style="color: #000000"><html>
<br />
<body>
<br />
<code>
<span style="color: #0000BB"><?php
<br />show_source</span>
<span style="color: #007700">(</span>
<span style="color: #DD0000">"test.php"</span>
<span style="color: #007700">);<br /></span>
<span style="color: #0000BB">?><br /></span>
</body>
<br />
</html></span>
