PHP如何检查第一个字符是否为£，如果是，则将其删除

Question

How exactly do I check of the first character in $value is £ and then remove it if is?

Even better would be to check if it is not a number and then remove it.

My current code:

echo '<dl style="margin-bottom: 1em;">';

foreach ($row as $key => $value)
{
    echo "<dt>$key</dt><dd>$value</dd>";
}

echo '</dl>';

You know there's a function for that? http://php.net/manual/en/function.str-replace.php

str_replace('£', '', $value);

or of course

ltrim($value, '£')

if you only want to get rid of the first character
