LEARN ABOUT PHP
ereg_replace
EREG_REPLACE(3) 1 EREG_REPLACE(3)ereg_replace - Replace regular expressionSYNOPSIS
string ereg_replace (string $pattern, string $replacement, string $string)
DESCRIPTION
This function scans $string for matches to $pattern, then replaces the matched text with $replacement.
Warning
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
PARAMETERS
o $pattern
- A POSIX extended regular expression.
o $replacement
- If $pattern contains parenthesized substrings, $replacement may contain substrings of the form digit, which will be replaced
by the text matching the digit'th parenthesized substring; will produce the entire contents of string. Up to nine substrings
may be used. Parentheses may be nested, in which case they are counted by the opening parenthesis.
o $string
- The input string.
RETURN VALUES
The modified string is returned. If no matches are found in $string, then it will be returned unchanged.
EXAMPLES
For example, the following code snippet prints "This was a test" three times:
Example #1
ereg_replace(3) example
<?php
$string = "This is a test";
echo str_replace(" is", " was", $string);
echo ereg_replace("( )is", "\1was", $string);
echo ereg_replace("(( )is)", "\2was", $string);
?>
One thing to take note of is that if you use an integer value as the $replacement parameter, you may not get the results you expect. This
is because ereg_replace(3) will interpret the number as the ordinal value of a character, and apply that. For instance:
Example #2
ereg_replace(3) example
<?php
/* This will not work as expected. */
$num = 4;
$string = "This string has four words.";
$string = ereg_replace('four', $num, $string);
echo $string; /* Output: 'This string has words.' */
/* This will work. */
$num = '4';
$string = "This string has four words.";
$string = ereg_replace('four', $num, $string);
echo $string; /* Output: 'This string has 4 words.' */
?>
Example #3
Replace URLs with links
<?php
$text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]",
'<a href="\0">\0</a>', $text);
?>
NOTES
Note
As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED
notice. See the list of differences for help on converting to PCRE.
Tip
ereg_replace(3) is deprecated as of PHP 5.3.0. preg_replace(3) is the suggested alternative to this function.
