<h1>PHP Function List</h1>

<?php if ($notfound && count($maybe) > 0) { ?>
|
|
|
|
<p>
|
|
Sorry, but the function <b><?php echo htmlspecialchars($notfound); ?></b>
|
|
is not in the online manual. Perhaps you misspelled it, or it is a relatively
|
|
new function that hasn't made it into the online documentation yet. The
|
|
following are the <?php echo count($maybe); ?> functions which seem to be
|
|
closest in spelling to <b><?php echo htmlspecialchars($notfound); ?></b>
|
|
(really good matches are in bold). Perhaps you were looking for one of these:
|
|
</p>
|
|
|
|
<?php quickref_table($maybe); ?>
|
|
|
|
<p>
|
|
If you want to search the entire PHP website for the string
|
|
"<b><?php echo htmlspecialchars($notfound); ?></b>", then
|
|
<?php
|
|
print_link('search.php?show=wholesite&pattern=' .
|
|
urlencode(htmlspecialchars($notfound)),
|
|
'click here');
|
|
?>.
|
|
</p>
|
|
|
|
<p>
|
|
For a quick overview over all documented PHP functions,
|
|
<?php print_link('quickref.php', 'click here'); ?>.
|
|
</p>
|
|
|
|
<?php
|
