PHP » Strings » ltrim()
- Syntax:
- string ltrim(string s [, string remove_list])
- s
- The string.
- remove_list
- Characters to remove.
Trims whitespace off the left side of a string.
ltrim() works just as trim() but only trims off characters on the left side of the string. The new trimmed string is returned. The optional remove_list parameter can be used to specify which characters should be trimmed off.
Examples
Code:
<pre>
<?php
$s1 = ltrim(" \t hello there \n");
$s2 = ltrim("--- hello ---", "-");
printf("[%s]<br>[%s]", $s1, $s2);
?>
</pre> Output:
[hello there
]
[ hello ---]
Explanation:
ltrim() is used on two strings, both with and without the use of remove_list.
